Victron MultiPlus-II 48/5000/70-50 4000W Inverter/Charger with Freedom Won Lite Home 10/8 LiFePO4 Battery N.

This system can discharge a maximum 5200W of AC energy for powering household loads. If fully charged, the battery would sustain that rate for about 1 hours. In order to maximise the performance of the system, it is best to discharge the battery slower by avoiding high peak loads. This system would power typical household loads of 1kW for about 10 hours.
