I have solar panels with 9.7A and 37V. 4 panels in one series will be 150V, but two series in parallel will be 20A. Would either scenario work with the SMA SB3.0-1 SP-US-41 Sunny Boy Solar Inverter?
1 string in series at 150V would work, but it may be late in the morning before it starts up since the minimum startup voltages are 100V / 125V on a 208V / 240V system respectively. 2 strings of 2 pan

Can I use a MidNite Solar MNEAC AC circuit breakers on the DC side between my solar array and the charge controller?
No, because it may destroy the MNEAC circuit breaker. Instead, use MidNite Solar's MNEPV DC circuit breakers on the DC side which would be between:
The solar array and the charge controller (the am
