[2022-12-15_08.36.05] [2022-12-15_08.36.14] Can someone help me out on how this works? I made sure my solar panels are indeed connected to the wire and that there’s electricity going through them.

Solar Panels emit ULV not LV. That is all. So either change the Batbox to ULV and then add one transformer to the Batbox, or add multiple transformers between the existing Batbox and the Solar Panels.
