My ac power (24/3000/70 Multiplus) cycles on and off every 3 seconds. Cerbo GX screen on and off and microwave. When it occurs, Cerbo screen shows 9w ac load, no pv data. I turned on ac load(lamp, phone charger) and Cerbo returned to normal, no cycling, screen then showed 85w ac load, pv 117w(cloudy). My BMV712 is not working. Why is this happening?
Hello Jeff, here you give us a puzzle with not much info.
Anyway: Start with making the system as simple as possible.
Start with only battery (Pos and Neg) and Multiplus and the AC out (L and N), check the grond ( should be one cable) ... disconnect every thing else.... if this works... start connection one more, test again, connect one more... test again.
Hope this will help. Rob
