1. Pure reverse type The direct current generated by the solar panel passes through the external charge and discharge controller, which usually charges the battery. When power is needed, the solar inverter converts the direct current of the battery into a stable alternating current for the load to use; 2. Mains complementary type City power main type: The direct current generated by the solar power generation panel charges the battery through an external charge and discharge controller; when the mains power is cut off or abnormal, the solar battery converts the direct current of the battery into a stable alternating current through the solar inverter for use by the load; this The conversion is completely automatic; when the mains power returns to normal, it will immediately switch to the mains power supply; Solar main supply type: The direct current generated by the solar power generation panel is charged to the battery through an external charge and discharge controller. Switch to mains power supply.
