Switch assisted our client with a back-up system big enough to keep our client’s 600 sq meters house switched on during loadshedding. We installed 1 x 5KVA Inverter/Charger (VICTRON ENERGY, 5yr Warranty) and 2 x 5kW Freedom Won Lithium Ion Phospate LifePO4 Battery (expandable with another 3 x 5kWh Etower stackable batteries).
