Hello all,
I am hoping to get adive on the best way to configure a system with the below specifications:
-8.1Kw PV DC coupled (via three Victron 250/60 Smart Solar Charge Controllers) to 48V / 500Ah flooded lead acid battery bank
-Multiplus II 48/5000/70-50 Inverter charger with AC Mains Input and AC Loads Output
-Cerbo S GX, Victron Shunt and BMV-712 connected also.
I want the following to happen:
-PV power to prioritize 1. Charge the Battery Bank 2. Any excess to AC Loads 3. Any further excess feed into the grid
-AC Loads to be fed from inverted power from battery bank up to 4.5Kw (there about), and (Power Assist?) the grid supplying power to meet the demand for anything over 4.5Kw.
-Mains to charge batteries when they are below a set threshold i.e not enough PV.
TIA, Jack
