I've basically been running an experimental setup modifying it as I go along and I don't ever leave it unmonitored or unmanned. But I've come to the point that I don't want to shut everything down every time I leave the house so I ordered some circuit breakers and things like that and started to try and protect the system so that they would not be any possibility of casualties.
I also realized that I had some issues with some poor mc4 connectors and heating and melting problems so I've had to make some changes and I'm pretty sure I'm doing a few things wrong here.
I have 14 panels (240w) going to a hvlv2424 inverter
I have everything 2 series. Would prefer 3s but its too close to the inverters limits
So 2s it is. One group of panels is 2s2p using cheap branch connectors and a 30 foot 10ga pv run. Combined to another 2s2p group in a different direction. The panels short circuit current is 8.37a per panel. The other group is 2s3p using branch connectors also with its own 10ga pv run. These all come together to a 63a santan solar (polarized? ) 63a mcb . A different group of panels 2s3p are also feeding the inverter independently.
How do i make this safe? I have a 150a battery circuit breaker but it was getting hot. So i removed it. Its also from santan solar
