Good afternoon and welcome to WAGO! Digitalization is advancing in many areas of our lives and is not stopping at our power and energy networks. This shows that the topics of the energy industry are not becoming less boring or simpler. No, on the contrary. The challenges facing grid operators in the wake of the energy transition are more demanding than ever. The expansion of renewable energies has not yet reached its peak and charging stations, stationary energy storage systems and heat pumps are increasingly being installed. However, none of this is happening in the high voltage grid, but in our distribution grid, decentralized in the medium voltage and lower voltage level. And the challenges associated with this are in turn linked to a dynamic that continues to grow, both politically and economically, but also technically and technologically. Today, we at WAGO want to give you answers and show you solutions on how to meet these increased demands in a future-proof manner. I would like to start at this point with an interview. A few months ago, we asked the Managing Director of Netzgesellschaft Niederrhein, Mr.Christoph Epe, about the energy transition. Mr. Epe, what makes the tension between the energy transition and regulation visible for network operators? The energy transition means that we are faced with a task that will inevitably produce costs and force new technologies. However, this is not really the focus of regulation. They have tried to adapt it a bit but one thing is that this permanent cost pressure on the costs of the network operator is a huge challenge, because on the one hand I have to master new tasks, integrate technology and on the other hand I have to reduce costs. I think that's a challenge that not many companies in Germany have and this will also put one or the other network operator to the acid test. And how can network operators keep a cool head? On the one hand, we have to approach politics together in order to influence the framework but without refusing and therefore not implementing it. And on the other hand, we have to join forces and do what we can actually do. And how can you shape the regulatory framework for yourself? Well, I do believe that we find the technical solution appropriate. The challenge is to reconcile the issue of costs and that's where the regulatory framework is needed. And there are two ways to do that. Either I try to move within the framework in the best possible way. That is what we have to do at the moment, because there is no alternative. At the same time, however, we should urgently try to influence politics via associations that the challenge of the energy transition will not be 100 % feasible and that perhaps a few changes to the regulated framework are needed. Mr Epe has just mentioned that the energy transition is forcing new technologies and requires additional investments. However, the regulatory framework is still missing. So the question is, how can we invest in a future-proof way when if the speed of innovation continues to increase? And for grid operators in particular, who have to plan the grid management and expansion, every new investment would become a kind of risk capital investment. But how can you counteract this uncertainty? With transparency. The more a network operator knows about the network, the lower the risk of a bad investment. This applies not only to grid operators, but also to company-owned own industrial energy grids. However, there are still far too many blind spots in these networks and the digital transformer station can make them visible. Good afternoon, ladies and gentlemen, today I would like to introduce you to the concept of the digital transformer station from WAGO. First of all, however, I would like to point out the difference between an automated, intelligent transformer station and a digital transformer station. An intelligent automated transformer station means the automation of the medium-voltage switchgear. For this purpose, a small telecontrol device is installed in the transformer station and connected to the control system via IEC 60870. The whole thing is end to end encrypted via a VPN tunnel. This makes it possible to collect position messages from the switchgear, to control commands and thus to automate the switchgear. In addition, the measuring devices from the medium-voltage switchgear can be coupled with the small telecontrol device via Modbus RTU and also transmit this data. For some time now, so-called digital drag pointer have also been increasingly installed in transformer stations to measure the low voltage. These measuring devices are also coupled accordingly via Modbus ATU and then transmitted to the control technology. The increased measurement of the low voltage is also the reason why WAGO has thought about developing the concept of the digital transformer station. Why is it necessary to increasingly measure low voltage in the first place? There are several reasons. Load profiles in households are changing a lot due to PV roof systems, heat pumps, battery storage and changing user behaviour. Redispatch is also a huge issue right now. This means the upstream network operator must be provided with real-time data from the local network. And the dynamics of e-mobility is also an issue that the network operator is very concerned about. That means massive load peaks are occuring in the grid and the simultaneity factor is unknown. Let's take a look at the PowerPoint again. Now I would like to show you the added values of the digital transformer station. There is the possibility to build another communication path via the MQTT protocol to a cloud or to a database. This path can be used to log and evaluate low-voltage measured values accordingly. Of course, limit violations can still be transferred to the control technology via the IEC 60870 protocol. In parallel, a CSV file can also be created in the WAGO small telecontrol technology. A third communication channel is the possibility of accessing the WAGO controller remotely or locally via a VPN tunnel or a HTTPS access. This gives me the option to parameterize the system remotely or locally. I can visually display the process or access it remotely and I can also retrieve the generated CSV file and use it for a downstream data analysis. Here is a small view of the web server of the WAGO small telecontrol device. As an example, here is the transparent display of the low-voltage main distribution. We are also able to establish another communication channel with our concept. In this case via LoRaWAN. This means I have the possibility to integrate a LoRaWAN network into the WAGO small telecontrol technology. I can use it to collect remote measured values from a meter and process and transmit them accordingly. I can also forward a switch command, e. g. for switching street lighting or for a decentralized grid-serving load management by reducing the power of charging stations. However, the WAGO solution also offers even more added values. There are, for example, a medium-voltage calculation, a decentralized wide-range control or a dynamic grid-serving load management. All these functions can be implemented subsequently by loading a Docker container. But WAGO offers even more. WAGO supplies complete system solutions for the digital transformer station. So let's take a closer look at this control cabinet, which is standing next to me. This is a real network operator application to make the medium and low-voltage network fully transparent. On the one hand, we hav routed the feed path here for the 230-volt supply via a fuse. Then it goes on to a lightning protection or overvoltage protection module and from there to the WAGO power supply, which supplies the WAGO small telecontrol technology with voltage and an additional communication medium. At the WAGO small telecontrol device we see the corresponding interfaces at the front. Once the Modbus RTU is routed to the corresponding transfer terminals. And the Ethernet cable is also led out and for example a modem can be connected. At the small telecontrol device itself there are several I/O modules. The first one is an 8-channel input module to collect comments, feedback from the short circuit indicators or the door contact switches. The next module, which is installed here, is a 2-channel Pt100 measuring module to measure the transformer temperature and the ambient temperature in the station. The most important is the energy measurement data provided by WAGO. The first module is a 4-channel module to measure the transformer output. Keyword "digital drag pointer". And the further measuring data, in this case 4 pieces at the number are there, in order to measure the individual 3-phase cable outgoing feeders. As you can see, we have also left a little space here. This means I can retrofit additional energy measurement modules of WAGO, in order to measure additional cable outgoing feeders. The concept is also very modular. This means that the current paths can be very easily forwarded to the transfer terminals with our X-COM system and the converters can also be short-circuited via a jumper. We then also offer these energy measurement modules as retrofit sets in order to be able to retrofit them very modularly and flexibly and to make the current paths directly pluggable. The voltage path is simply bridged from the previous terminal to the new terminal. I already mentioned the communication medium at the beginning. As WAGO, we support where the most diverse communication media fiber optics, SHDSL, DSL, WT and leased line modems, 5G, 4G, the topic f LTE 450 megahertz and also LoRaWAN, so all of this is possible with the WAGO technology. Another important point is the topic of security. That means the WAGO systems must of course be operated securely. On the one hand, we provide firmware that complies with BDEW white paper, but we also support things like a firewall, a user and role concept and so on. In summary, I would like to briefly point out the added value of WAGO. So we have a very flexible, compact hardware with appropriate interfaces for critical infrastructure and extensive I/O modules. We have a hardened firmware which enables the device to be operated securely. We have future-proofing on board, so that applications can be reloaded at any time for tomorrow's requirements. And yes, we provide complete system solutions for the digital transformer station. In the next part you can see the application Grid Gateway, which makes the whole thing very easy to parameterize via a web server. I would like to introduce the WAGO software Grid Gateway for your digital transformer station. Here you can see your automatically read in hardware structure of the PLC. You can parameterize this by configuring and clicking. Thus plain text names can be assigned, like door contact or UPS fault as well as simulations which are also needed for a bit test. In addition, you can read and write Modbus participants. This is especially important for ground fault and short circuit indicators. The data can be transferred to a cloud very easily. All you need to do is set the parameters and you have a cloud connection. If you want to make it very easy, use the data logger on the device, which is stored in your station. Here, up to 80 data points can be stored directly in your station. Date and time can be attached to make traceability easier later on. Use the function of the transformer overview of your mean voltage as well as low voltage outputs. Here you can parameterize up to two transformers and 15 low-voltage outputs. You have an overview of your real-time values such as voltage, current and the maximum power. A digital drag pointer here of 70.7 amps measured with date and time for each individual phase. In addition, it is possible to get weather data, such as the global radiation or the transformer or air temperature. Another feature are logic functions such as for the voltage band violations a comparison to the voltage of 245 volts for an overvoltage violation or and building block. This can be used for collecting faults to map door contact, UPS and others to a message to your 60870 scada system. To do this, switch to Communication IEC 60870 and here you can simply parameterize individual messages or various others and transfer them to the table. I have prepared this for you once, you see this here on the right. These messages are simply transferred. If you have further questions, please contact us at any time. It is important that hardware and software are perfectly coordinated with each other and even better results can be achieved if other devices used in the field supply their data to the transformer station or are controlled from the transformer Station. But how this is technically implemented is now explained to you by my colleague Jens Sparmann. Hello and welcome! Today I would like to talk to you about the topic LoRaWAN @WAGO and how you can use it to bridge the last mile. You're familiar with the digital feed-in station or transformer station from WAGO. Here you can implement communication to the process control technology or to the cloud with WAGO hardware, or classically communicate via IEC 60870 or 61850 . We can measure control, regulate or implement classic monitoring in the digital transformer station. But what about the last mile? What about the feed-in power of a customer's PV? What about the load management of a charging infrastructure? Or a classic lighting management? How do you bridge the last mile to measurement, control, regulation or classic monitoring? LoRaWAN is predestined for this. It works in Europe in the 868 megahertz frequencies, it has ranges of 2 to 40 kilometers, it is 128-bit encrypted and some sensors have such low energy requirements that they have a runtime of up to 10 years. What does all this have to do with WAGO? You can classically use the WAGO controller as a data aggregator and, with a little additional hardware, send your data directly to a LoRa network, e.g. with a LoRa Modbus gateway. And with that you can easily bridge the last mile. If you have any questions about this, feel free to contact us and perhaps there will be something on the subject of LoRa network management from WAGO. Another major task for the grid operators is the legal requirement Redispatch 2.0, which all grid operators and municipal utilities have to fulfil. But what exactly is behind this and how the WAGO Energy Workshop supports you , will be explained by my colleague Christian Schubert. What is behind the term Redispatch 2.0? With Redispatch 2.0. distribution network operators and municipal utilities in Germany now also have to deal with network congestion management. No matter whether there are bottlenecks in their own network or not. Where does it come from? Redispatch 2.0 is the challenge arising from the grid expansion acceleration act 2 0. The fundamental amendment of the feed-in management requires complex technical, operational and organizational adjustments at all grid levels. The legal requirements therefore affect all network operators in Germany. What is the goal? The reorganization of congestion management requires new complex tasks and responsibilities. It requires the involvement of all controllable power plants. This means that it requires a coordination process between the different grid levels and it obliges the grid operator to participate in congestion management in upstream grids. Data is also the basis for Redispatch 2.0. Do you know the saying from computer science 'Shit in - shit out'? If you record incorrect or incomplete data, you will only receive incorrect or incomplete results in the evaluation. At this point, any data-supported process fails. The WAGO Energy Workshop helps you deal with data. To do this, we work with you to equip one transformer station in your local network area so that the profile data can be generated and made available for possible further processing into a network bottleneck forecast. Up to 3 municipal utilities work together under the guidance and moderation of WAGO in a boiler-suit-phase to develop the technical requirements for a so-called monitoring, in order to support the uniform redispatch regime. Learn about your tasks together with other colleagues from your industry. Wew will make the connections for you. Now there are not only transformer stations that are located in a local network. Let's think about the many stations in industrial plants or that supply shopping centers or the stations where renewable energies are fed into the grid. I am talking here about customer transfer stations. What task these have, what differences there are to the digital transformer stations and what WAGO solutions we have for them, my colleague Andreas Siegert will explain to you now. What are customer transfer stations and how do they differ from transformer stations? Well, that is an exciting topic and I'd like to explain it to you in more detail. Transformer stations have the task of supplying residential and small business customers with energy. You know this. Take a look down the street, you'll see little concrete houses like this, they're usually transformer stations and that's just familiar. The boundary of ownership and responsibility is at the house connection box. This means that everything in front of the house connection box is the responsibility of the network operator. And everything behind it is the responsibility of the customer. Let's take a look at the customer transfer stations. Customers transfer stations supply customers who have a high energy demand, somehow large customers, industries and so on. And here it is the case that these customers usually also operate their own medium voltage network and also operate transformer stations and low-voltage networks. This means that the handover station or the handover takes place here directly in the customer transfer station. Everything behind it is the responsibility of the customer. How can these customer transfer stations contribute to the energy transition? Well, customer transfer stations are essential for the energy transition. Why is that? Well, for that I have to go back a bit. What was it like in the past? In the past, we've really only had a one-way energy flow direction. Nuclear power plants and coal-fired power plants have fed in their energy at the high voltage levels and consumption was at the low voltage levels. And that has been changing in recent times, mainly due to two factors. One is renewable energies, which are also feeding in at lower voltage levels and thus reversing the direction of the energy flow, and the other is the load profiles due to the behaviour of citizens, including electromobility. And in the past we were practically blind. We didn't know what exactly was happening in these stations. They were calculated once, they were designed accordingly and everyone was happy for decades. Well, now we have new challenges and we have to accommodate this whole variety of renewables in our grid. We know the federal government has set targets of 65 % renewables by 2030 and even 100 % renewables by 2050. This throws our grid into tremendous disarray. And what used to apply doesn't apply in the future. But we can put a lot of copper in the ground now. That's one solution. That is expensive. That takes a lot of effort. And in some situations, it's also the right solution. Another approach is that we simply make much better use of the existing grid infrastructure. And we can do that by making the energy flows transparent, by connecting the grid station, the transfer station to the control technology of the grid operators and transmitting information about load flows, about the quality of the grids, about ground-fault and short circuit indicators. And the network operators have recognized this and have laid it down accordingly in their technical connection rules. And this is where WAGO comes in. WAGO supplies the telecontrol technology, WAGO supplies the hardware to make such stations correspondingly intelligent. But we also supply the software and in this case you no longer need to worry about the data models themselves, which apply, for example, in the network areas of E.On Netze BW, EWE or even Westnetz. You can select them yourself via our new free library by mouse click and e.g. include the ground fault and short-circuit indicators and also select the data models if they are in another area. WAGO offers all this and makes life easier for our customers. With this in mind, I would like to thank you very much for watching. Thank you, Andreas, for the overview. Philipp Baumann will now show you the matching software. Hello, we at WAGO have a hardware as well as software solution for the remote connection connection of customer transfer stations according to the technical connection conditions of the network operator. To do this, you have two options. The first: You can install a library module yourself using the application note with our WAGO software e!Cockpit or option two: You simply have it done at our factory. No programming knowledge is necessary for either. I will now show you an insight into the softwareinterface. First, you select the network operator in a drop-down menu. In this case I chose E.On. Here you see the input fields as well as the transfer fields according to the technical connection conditions and on the right side the data point list, which was used for this. Here digital contacts can be selected, in order to be transmitted e.g. switch positions or error messages. Furthermore, you have the possibility to implement Modbus devices also again in the drop-down menu. An overview of all set parameters, that are made available to the network operator, can be seen at the end in the form of a table. You can also save these configurations as a backup and restore them later if necessary. As an outlook into the future I would like to tell you that we will integrate QU protection relays and of course you have the possibility to combine the whole thing with the power plant control library. Thank you very much. Philipp has mentioned the power plant control library in his software presentation. But what exactly is a power plant controller? I ask this question again to my colleague Andreas. This time, however, not here in the studio, but up near WAGO on the roof. Basically it is quite simple a power plant controller is something like a remote control or a gas and brake pedal for the grid operator. In somewhat more technical terms, it means that a grid operator specifies certain setpoints that a plant has to comply with, measures and checks these set points at the grid interconnection point and passes on any deviations to the generation units so that the set point specifications can be met. Let me give you a simple example Suppose we have a sunny day. The plant is humming, not like today, it is at 100 % of its rated power and the grid operator has to protect its grids because the grid capacity is limited. That is, the grid operator now specifies: Dear plant, you are only allowed to feed in 70 % at the grid interconnection point. The power plat controller now receives these values and sends them to the inverters in the plant. The inverters in turn generate this 70 % energy, but only at the decentralized point where they are sitting. Now, in larger parks, we usually have line lengths to the grid interconnection point of let's say half a kilometer. That's quite common. It can also be more, so that we have losses on these lines. Now, we're going to assume that we have losses of 5 %. This means that only 65 % of the required value arrives at the grid connection point. The power plant controller, recognizes this immediately and now readjusts and sends a value, let's say 75 % to the inverters. They inverters implement this and this now only leads to the fact that the required setpoint of 70 % is actually reached at the grid connection point. What is the background, why do we need a power plant controller at all? How was it in the past and why does a power plant controller actually have to be certified now? Well, in the past we had a lot of rotating masses from power plants in the grid and little renewable energy. This share has increased in recent years and we have also shut down power plants, so that these rotating masses are missing. This means that in the future these renewable energies will have to take on more tasks that concern grid security. And all this is defined in the European Grid Code, the NC RFG, the Network Code Requirements for Generators. And it also lays down these rules for generation plants. As in road traffic, everyone must know what they are doing so that we can all drive sensibly according to the rules. And so every participant in the grid, be it producer or consumer, must also comply with these rules. And that the countries in the European Union are now required to also develop these specifications nationally. Germany has done this with the VDE application guidelines 4105 for the low voltage, 4110 for the medium voltage, 4120 for the high voltage and 4130 for the extra high voltage. Just by the way WAGO has had its power plant controller certified for medium voltage 4110 and for high voltage 4120. Since April 27th 2019 plants have had to implement these requirements. There are certain transition periods, which can be demanded by the network operator, so that plants can also be put into operation according to the old medium-voltage directive. In this case, a certified power plant controller is not necessary. This mean that all plants larger than 135 kW that want to feed into the medium voltage must now meet these requirements of a certified power plant controller. By the way, not only the power plant contoller must be certified, but also the generation units. What does the WAGO solution actually look like? I have to say that WAGO does not supply a plug-and-play power plant controller, as you might think at first. We have chosen a different approach, because we have actually been providing such controllers or the components for our customers to be able to realize such a solution for years. What WAGO is doing now, we are actually improving this baking mix, so that we provide a certificate and a certified component that runs on a PLC as a software part so that our customers still have the possibility to build their system flexibly. Because every plant looks different and every plant has its own peculiarities, and with our system, customers can react very flexibly to these requirements. For example, our PFC, which is very powerful as a programmable logic controller. Together with the I/O system, so that various messages can be taken from the field, but also a user management can be set up. A UPS that can be brought to it. As you can see, we supply the ingredients our customer bakes the cake. The background was, that we wanted to interfere as little as possible in the customer's know-how and we succeeded with that. And this product is very well received in the market. The other is the issue of security, because if you have to play in the energy market, you have to take care of the security requirements. A very simple example here as well: WAGO has two interfaces that can be controlled independently and separately from the direct marketer and also from the grid operator. Both can establish a VPN connection directly into the controller. The last point is the topic of future security. The PV industry in particular is plagued by companies that have entered this volatile market and then disappeared again. And our customers need a reliable partner here at this point who is solidly positioned and WAGO offers this security. I would like to thank you and return to the studio. Now we are talking about the topic of load management. In order to avoid an overload of the power grid, e.g. due to the simultaneous charging of electric vehicles both at a public charging station or at the wallbox at home, load management must be used. But what is meant by this? And how is it technically implemented? You will find out in the next part. What is load management and what is the difference to energy management? Well, in very simplified terms, a load management is a management for loads. That was clear. But I would like to explain to you exactly what this looks like using an example. Imagine you are a doctor, you have a practice or you own a car dealership or a shop and you want to offer your customers charging infrastructure in the future. Perhaps you also want to make this possible for your employees. Which, of course, immediately makes you much more attractive as an employer. Well, you now submit an application to your network operator and ask whether this is possible without further ado. A few weeks later, a letter arrives at your home and you see a calculation that tells you that you will soon have to spend tens of thousands of euros on it. You are terrified and don't know what to do now. And then you hear that WAGO offers load management. You find out about it and realize that there are other ways to solve your problem. Take a look at the slide. There's a grid connection point and there's also the consumer side shown here below with the vehicle. Those would be your charging points. They must ensure that at all times the requested power for your electric vehicles is not higher than your grid connection capacity. If you don't do that or you don't pay attention to that, then your fuses will be tripped and you won't be able to continue charging your vehicles. How can you prevent this from happening? Well, WAGO's load management helps you by measuring the grid connection capacity accordingly and by controlling flexible loads. WAGO provides you with various options here, firstly the intelligent controllers, the PLC's on which you are able to program here appropriate load management and your plant-specific system. If you now also want to integrate generators such as photovoltaics or biogas or even storage in your system, then you need more than just management. Then you need an energy management. For WAGO, it makes no difference whether you program load management or energy management. By the way, you can also implement other things such as OCPP or EEBus. All of this is provided by WAGO. Thank you, Andreas. I'll come back to the customer transfer station. This time, however, not from the point of view of the network operator, but rather from that of the customer. And I would like to talk to someone who has already been able to gather initial experience and who is also expanding this solution in order to process and analyze measurement data in the cloud. I am now joined by Marco Genehr from Ingenieurbüro Pfeffer in Rödermark. He is responsible for the management, project planning and sales in the southern region. Hello Marco! Hello Heiko, nice to be there today. I'm glad about that, too, Marco, we start right away with the first question: Why do cloud solutions for measurement data make sense? Small and medium-sized companies often do not have a central place where they can store measurement data. For this reason, it is good to have access to a ready-made solution where the data can be stored. We always have a bit of a big data problem with measurement data. A lot of measurement data is generated and if a smaller company wanted to set this up on its own, it would have to install SQL servers, and build visualization tools with which it can more or less display this data visually. In addition, a cloud solution always has the great charm that you can access the data wherever you can access the Internet with a web browser. Which tasks can all be solved with this? The customer has the possibility to get a deeper insight into the supply structure from his station or from his complete operation, to analyze the load flows and to collect knowledge, at which points do I have which power flows and at what points in time? Especially if you are operating in a mixed structure where in additon to the actual supply for machines for production plants, you also operate, e. g., PV plants or biogas plants, where you can only feed back and you might also have your own charging infrastructure e-mobility or e-forklifts, which you want to charge. Then it can be useful to know a little bit more precisely at which times you draw more and at which times you might feed back more. In addition, you also have the possibility to analyze the data after faults, where they came from and you can gather the initial findings and then also preventive findings for the future on how you can do it better. On the subject of disruptions, do you have a concrete example for us? Yes, for example we once had a network failure in our building in January And when I looked in at the data, it became clear to me that it had simply been too much, the heat pumps were running, at the same time we were charging the forklift and it was altogether simply too much load. The PV system did not run and that's why the fuse has knocked us out. But you can surely display that again with a graphic or something like that, so that you can evaluate it. Yes, so in any case I saw that in the in the long-term graphic, as I said, I looked into the cloud and then saw the errors there. Another question: How did you do it now with WAGO? Do you use WAGO? I see one of our controllers in the background. Yeah, of course. Sure. It's my test setup, where I always try out when there are innovations and also in order to parameterize systems that then go out into the field. Yes, it works wonderfully with the PFC 200, a controller. You parameterize or you configure it so that there is connection to the cloud. Then you install a paramterization software on it which is web-based and works with the web server. And there you can set all the data as you need it in the cloud. The connection is then immediately in the cloud. Then I can take the corresponding measurement data points in the cloud itself and can drag them into into visualizations and have the data displayed as I need to see it and what I want to know. Are there any other advantages to using the WAGO Cloud at this point? I mean the keyword data security. Yes, of course, in the cloud we have a secure storage of the data, so both the access to the cloud has a certain security, but also the data storage itself and the data backup there. The cloud is located somewhere in a data center, where people work very hard to ensure that the data is always backed up also the hardware is always 100 % functional. Okay, Marco, thank you very, very much for the interview we just had here. I hope to see you in person again soon. Not just connected via video conference. I'm looking forward to maybe being there when the Smart Grid Lab Hessen opens, which you are working on very, very intensively. Thank you again and take care. Yeah, you too. See you then, bye. We had already mentioned it earlier that renewable energy generation should be 65 % in 2030 and we will make the 100 % 20 years later. To generate these amounts of energy, we still need to install some wind and solar plants. But these also require a safe and fast connection technology. We would not be WAGO if we did not have a suitable solution for this. And as the world market leader for spring connection technology, we have revolutionized the customer connection. Hello from my side. Today I am introducing you to the new WAGO connection technology for applications in the field of renewable energies. Renewable energies are on the rise. The combination of power generation by wind, water, sun, the simultaneous storage and later consumption by electromobility pose new challenges for many companies in this sector. Higher performance is required and faster and easier deployment in the field. As we can see from the Fronius example, this is the new Fronius inverter, it is important that the installer in the field can easily access the connection technology and disconnect it. But thay can also connect them. We as WAGO have been supplying the renewable energy market for many years. Here we focus especially on selling high-quality products, because especially in the field of renewable energy, i. e., in the field use, the ambient temeperatures are particularly harsh, there are very high temperatures, low temperatures. In addition, we have vibrations and the hard handling by one or the other hard hand. For this, our WAGO products have been in use for many years, as we see here in the picture from the typical WAGO terminal block 222 to the PCB terminal blocks with levers. These products are used in devices such as solar inverters, battery storage systems, wall boxes and charging stations and many applications in the field of renewable energy. Examples can be like the AC connection of a wall box or the connection technology for a battery management system. Here we talk with our customer about the requirements and find the right solution. We talked about this with out customers, which points are very striking for you? Distinctive points for the customer were fast, simple and safe. We have made a special effort in the area of safety. We have integrated the locking latch. The frontal locking mechanism allows the plug connections to be disconnected, but only if this is desired. Now I would like to use this picture to introduce our new product to you. MCS Maxi 6. The connector up to 10 mm². As we can see here on the table. It has a distinctive advantage? And that is the lever again. The lever is the distinctive element, which makes it easy for the customer to wire or even disconnect the conductor. Simply open the lever, insert conductor. and by pressing lightly close the lever and the conductor is connected. The lever makes it possible to connect without tools. And this in many, many applications in the renewable energy field. If we look at this housing bushing it is a standard housing bushing as it is often used in the field. We see the situation where a wire-to-board connection takes place, and here we see the difference from the previous interlock, so that we have a plug-in disconnect by pushing it sideways. and by simply pushing it back in and a small audible click, the connection is re-established. We have the right lock for every application for our pluggable connector system. Now I talk all the time about the fact that we have the lever and what advantages. And yet one or two electricians or even developers of these devices will ask themselves 'Why should I use the lever in general?' The question is just as simple as it is quick to answer, im terms of how the lever plays out its advantages in the field. Tool-less, intuitive, safe and fast. This means that we also meet the requirements of our customers. If I may show you this connector example: we have connectors in one hand, we have a conductor in the other hand and in the past we needed a third hand to operate tools. This has been taken care of with the help of the lever. The electrician opens the lever and closes it easily tool-less. But we as a WAGO are also thinking about how to meet the issue of higher performance with small housing sizes For this I would like to highlight our 6 mm² PCB terminal block with lever. Because this can accomodate a conductor up to 10 mm². This means that it can also carry the higher current and thus we get more power with the same size via our PCB. As you can see, we have a wide product portfolio. that can fit your application exactly. And also here we have to mention that we always have new additions. In the front area we see our current stars once the MCS Mini to 1,5 mm². As well as our new 221 inline splicing connector with lever. Let's work together to find the right connection technology for your application. Thank you for your attention. The energy transition poses major challenges for our energy networks and their operators. This is not yet noticeable everywhere but digitalization cannot be stopped; on the contrary, it offers the opportunity to optimize our power grids cost-effectively and efficiently. Only through monitoring in the transformer station do we create transparency and is load management possible. Only through the power plant controller are renewable energies not switched off, but regulated. We at WAGO support you with our hardware from the terminal block to current and energy, measurement technology with control and telecontrol components up to software applications in mastering this exciting task. Please contact us! Thank you for watching.
