My home has had solar cells since 2022 with a German inverter (SMA) that gave up and could not be used with batteries. Today, a new inverter (bidirectional) with battery was installed by Bjäre Energiteknik. With the application that came with it, I think I can see that with the gap in the cloud cover that was, the roof powered the entire house and also delivered a few W to the battery. Wonderful. Actually, I can't judge the equipment delivered, but I can judge the way that Bjäre Energiteknik handled the quotation work and installation. As a former entrepreneur in the mineral industry, I can say that this was done completely according to plan and in a very good way. I can therefore only highly recommend Bjäre Energiteknik but ask to come back with a review of the equipment delivered when it has shown what it is capable of. But even after about 3 hours of operation, it looks really good there too.
