We've designed a 5.50 kW DC solar system for your residential property in Johannesburg, Gauteng, providing a significant reduction in electricity bills. You'll be using 10 high-efficiency JA Solar 550W panels, paired with a Sunsynk 5kW Hybrid inverter and a 10.2 kWh LiFePO4 battery system (2× units). The geyser runs on solar surplus during the day — excluded from battery backup — which keeps the system right-sized and cost-efficient.
