My Solar Panel Circuit Breaker keeps popping and I canít work out why. I have two 12v 125w panels connected in a parallel configuration through separate 10amp CBs to a 30amp regulator. One CB keeps popping and the other doesnít. The odd bit is it only pops when the weather quickly turns from hot and sunny to rain. Full sun all day is fine. Rain all day is fine. Full sun to rain and I get a popped CB Ė just the one though.
Now I need to start swapping connections to see if itís the CB or the panel but access is predictably difficult. It may be easier to live with the issue. I just wondered if anybody has any bright ideas as to the cause.
