The system is built by installing solar panels on the roof or open ground and placing inverter in the house to provide electricity for the household appliances. For some households where the mains is not reachable, or the mains supply is unstable, it can solve the problem of daily power shortage and maintain a normal life.

How does a home off-grid solar system work?

Home-use off-grid solar power supply system generally consists of a PV array composed of solar panels, solar charge/discharge controller, battery bank, off-grid inverter, DC loads and AC loads, etc. If the output power is AC 220V or 110V, an inverter is also required. The solar panel converts solar energy into electric energy when there is solar radiation. The solar charge controller supplies power to the DC loads meanwhile charging the battery pack; when there is no solar radiation, the battery pack discharges to supply power to the DC loads through the controller. The storage battery also needs to directly supply power to the independent inverter which converts DC voltage to AC voltage and power the AC loads.
