Hi, I am new to this forum. I have installed an SPF 5000 inverter with 5kw of solar panels and 2 pylontech US 3000 c batteries. The installation has been running since April and through the summer it appears to have been fine. This week for the first time when the battery fell below 30% the utility did cut in but it tripped the RCD in the main distribution board. This happened every morning when batteries are falling below the cut off point, on some occasions it has also tripped the RCD protecting the utility AC in. I can’t establish if this is a problem with the inverter or my electrical installation, has anyone any thoughts.
