How does a solar off-grid inverter work?

1. Pure reverse type
The direct current generated by the solar panel passes through the external charging and discharging controller, which usually charges the battery. When electricity is needed, the inverter converts the direct current of the battery into a stable alternating current for the load to use;

2. Mains complementary type
The main type of mains power: the direct current generated by the solar panel is charged to the battery through the external charge and discharge controller; when the mains power is cut off or abnormal, the direct current of the battery is reversed by the solar battery through the inverter and stabilized. The AC power is used by the load; this conversion is completely automatic; when the mains power returns to normal, it will immediately switch to the mains power supply.

Solar main power supply type: the direct current generated by the solar power generation panel is charged by the external charge and discharge controller, and the battery is charged. When the battery capacity is insufficient, it will automatically switch to the mains power supply mode.
