This project called for a large fully off-grid system for a family of four in their Brand new 350 Sqm home. The system required a 10kw ground mount system for the Solar Pv Modules, connected with a large 10kw Victron Quattro Inverter/charger. The batteries used were two BYD Premium LVL 15.4 kwh giving them plenty of power all year round with back up generator only used once every 2-3 months.
