A customer wants to have his PV installation working ok and have electricity in his entire house, even if a power outage occurs.
I am planning to connect the mains to the AC-in and all the distribution board to the AC-out of a well dimensioned MultiPlus-II. Also install PV panels, MPPT, BYD battery, Venus GX and an energy meter.
Will this ESS system provide backup and normal performance even in the event of a power outage?
I am not sure all Victron devices will continue working with no grid power, but with sunlight and energy in the battery.
