1、This solar controller adopts high‑end MCU chip, which can realize intelligent control. 2、Having overcharge protection, overdischarge protection, electronic short circuit protection, overload protection, battery reverse connection protection, and solar battery reverse connection protection. 3、The series‑type PWM charging main circuit is adopted, which reduces the voltage loss in the charging circuit by nearly half compared with the charging circuit using diodes. The charging efficiency is 3% to 6% higher than that of non‑PWM charging, which increases the power consumption time. 4、The boost charging of over-discharge recovery, normal direct charging, and automatic control of floating charging make the system have a longer service life. 5、Three working modes can be selected: normally open mode, pure light control mode, light control plus timing mode, with a discharge control function that uses battery discharge rate characteristics to modify. 1 x Solar Charge Controller Item Type: Solar Charge ControllerMaterial: ABSModel: YH0612Charging Method: PWM Adjustment MethodCharge and Discharge Rated Current: 5AVoltage: 6-12VLoad Power of Solar Panels: 6V 5A≤30W; 12V 5A≤60WController Protection: Overload, Reverse Connection, Overdischarge, Overcharge, Open Circuit, Anti-backflow, Etc.No-load Current: ≤6mAWorking Temperature: -40℃-55℃
