High-efficiency monocrystalline solar PV panels on the roof collect the sun’s energy each day. DC charged power drives an on-board LiFePO₄ battery pack (optional ~5 kWh to ~30 kWh) to store surplus energy. A high-intelligence hybrid inverter manages power supply, converting AC if required but also driving critical appliances directly in DC to minimize losses. In practice, 24/7 operation is facilitated: solar charges batteries during the day and turns off automatically at night to battery energy.
