Hi guys,
I am planning to install a system according to the overview below where I normally use three Multiplus inverters + B-Box 13.8 kWh for self-consumption but also for occasional emergency power.
I read the advice on the Victron/BYD minimum battery size in the link below and there was some confusion! The minimum battery size table for Multiplus 48/5000/70 Three-phase states:
- Self consumption minimum battery = 1 x 13.8kWh
- Off-grid minimum battery= 3 x 13.8kWh (my calculations give 2 x 13.8kWh here)

I am struggling to understand if this is a requirement or a recommendation.
So my questions are,
Will this system work?
Why does Victron recommend using 3x13.8 kWh for off-grid use?
Does the battery capacity have to match the inverter maximum currents? I'm ok with not getting up to 3x5 kVA out from the inverters.
Thanks in advance! :)
