Working principle
The PV control module converts current into DC module, charging for the load and battery. At the same time, when battery voltage is low, the rectifier module automatically switches, to ensure the stability of the power supply system; when battery voltage is recover, the mains module automatically disconnects, ensuring PV priority.
Characteristic curve
When the solar module output is 3000W, its characteristic curve as follows:
