The solar off-grid system is mainly composed of solar panel, inverter with built-in transformer, controller and lead acid battery,cable. In daytime, when there is sunshine, the solar panel can convert the solar energy to electric energy and store it in the battery. At night or rainy or cloud condition, the battery shall supply power for load.
Advantage of the solar panel:- Using 182mm*182mm size high-efficiency monocrystalline silicon cell production, the module has excellent performance in space utilization and efficiency;
- Efficiency≥20.79%;
- Ensure the positive tolerance of module +5W, module power ≥450W;
- Low open circuit voltage.
|  |
Advantage of the off grid inverter: - Wide input voltage range and strong adaptability;
- Seamless switching without affecting continuous load operation;
- Built in transformer, strong bearing capacity, can withstand 2~3 times of surge power.
|  |
Advantage of the Controller:- MPPT working mode to achieve maximum power point tracking control; Automatic identification of battery voltage;
- The load control mode has light control and time control etc.
