I'm trying to choose an inverter for a PV self-consumption system with LiFePo4 batteries. The plan is to run on battery when SOC is above 20% and switch the loads to grid when SOC drops below 20%. The battery must NOT charge from the grid when the loads are on the grid.
The Multi RS looks like a good fit, but I could not figure out if it has the option to DISABLE GRID CHARGING and keep only PV charging.
I've read the manual but it does not say anything about this.
I've looked in the VictronConnect Demo Library but I didn't find the Multi RS there.
The manual does mention that the "backup generator" output can be configured to switch based on SOC and I think I can use it to connect / disconnect the grid at the AC Input using an external contactor.
But I'm concerned that the Multi RS will try to charge the batteries from the grid at night and I don't want that. It should wait until there's enough PV to charge it.
Does anyone know if Charging from Grid on Multi RS can be disabled?
