I have a system with 2x MPPT, VenusGx, Multiplus 3000/24/70 and 540Ah 24V battery bank.I wonder if I can disable the Multi charger. This would be useful in the following situation: cloudy days in which I don't have enough PV power to feed both the Inverter (AC loads) and charge the battery. In these conditions, rain, and so on, I avoid depleting the batteries, so I turn on the Multi to work from GRID.
In this scenario, the Multi will begin powering everything, charge battery and AC out. But I believe I could still use the PV power to finish charge the batteries, and use the GRID only to the AC loads. Later when PV power is over, I would enable the Multi charger again to make sure batteries get 100% SoC.
Is this possible? In the Multi input current limit(on Venus), I can only set 3A as minimum. I don't want to load new VE. configure settings on Multi just for these specific situations.
