No need to switch them off and on. Likely you will get solar from both arrays at the same time even though they are facing away from... -
Simple solution, 1) Use an All-in-One type inverter with 2 independent MPPT inputs (1 for each array) 2) Use an AoI inverter with only...

Typical off-grid charts explains the situation: Before the next solar production begins at about 6am, the batteries had a remaining SOC...

I find that mismatched panel actual production versus theoretical can have a few surprises. Partly this is because it is rare to hit...
