Battery or load priority in off-grid setup

Hi dear community,

I am designing a DC coupled off-grid system with PV+Smart Solar MPPT charger, Li-ion battery, Multiplus II and Cerbo GX.

Could you please tell me if by default VIctron has a battery charging priority in off-grid setups or load supply priority? If so, what is the SOC setting below which the priority is given to charging the batteries?

For example, what will happen if my battery is at 40% SOC and the PV generation is enough to cover the load? Will the system use the PV power to charge the battery or supply the loads?

Thank you in advance.

@Khachatur

With off grid, loads are priortized then battery charging.

You can set ac out 2 to switch off larger loads (and only switch on above a certain soc) to prioritze critical loads and battery charging.

So in short.... You can program it and set it up how you need it.
