Small update about OVP mppt circuit. As I said earlier, I have a relay on the board that turns on/off the BAT-12V converter that powers all MPPTs. The converter has low ESR capacitors at the input, which stuck the relay together during one of the subsequent tests. So I'm making a small soft start circuit: a serial NTC thermistor, or a resistor + relay powered from the output.
Moreover, in this casing I placed a caps mppt pre-charging system - behind the kilovac relay, activated manually with a switch.
