Description

technical field [0001] The invention relates to an electric power supply control system, in particular to an electric power supply control system with wind-solar storage and mains power complementary. Background technique [0002] The photovoltaic power generation system uses photovoltaic panels as power generation components, and regulates and controls the generated electric energy through the controller. On the one hand, the adjusted energy is sent to the DC load or AC load, and on the other hand, the excess energy is sent to the battery pack. Storage, when the generated electricity cannot meet the load requirements, the controller sends the electric energy of the battery to the load. After the battery is fully charged, the controller must control the battery not to be overcharged. The controller must control the battery from being over-discharged and protect the battery. The battery can store energy to ensure the load's power consumption at night or in rainy days. Howeve...
