This Victron Multiplus-II Inverter Kit functions as a UPS system and would be CoCT approved. The Kit allows user to draw up to 4000W (1C) momentarily and the battery capacity (5kW+ Lithium) allows for a consumption of 5000-Watt Hours (5kW Hrs) max. Once grid (Eskom) power returns unit will switch over to grid (allowing grid power through to power output and then start recharging the battery). Once grid fails, it will switch to Batteries again and so on. It is simple to add another 5kW Battery if needed.
