So, I've got my system setup with a hefty 75kWh battery and a solar array, but unfortunately my Sorotec Revo II has blown out. I tried troubleshooting it with the manufacturer who gave me a new main board, which I replaced into the unit, but the problem persists. They have since then stopped responding to me completely so now I am reliant on you guys to help me fix it.

It recognizes the incoming solar (just the volts, no amps). It can not produce AC power or even charge the battery, which it recognizes. It stays on with battery and/or solar.

I am able to produce pictures and multimeter testing.

Originally what blew out were the MOSFETs. I think what caused the issue was the surge from switching from grid to battery. In fact, I saw it happen live as I did the switch. Before switching the main board, it would short when turning on battery power, triggering the circuit breaker instantly.
