Introductions:
The 20A /10A 12V/24V Auto Switch PWM Solar Panel Battery Regulator Charge Controller is designed to always keep the battery on fill voltage condition, preventing battery from over-charging, over-discharging and reverse charging. Compared with solar charge controllers that are commonly seen on the market, this PWM controller can increase efficiency by 10%-30%. It can charge and discharge at the same time. What's more, it has perfect SOC function, supports charge current control and offers power control to the loads.

Features:
1. Increase efficiency by 10%-30% compared with other solar charge controllers
2. Can charge and discharge at the same time
3. Perfect SOC function, control charge current, supply power to the loads
4. Always keep the battery on fill voltage condition
5. Prevent the battery from over-charging, over-discharging and reverse charging
6. Offer reverse polarity protection for the battery and solar panels
7. Automatically cut off the load from the system when the battery voltage is low
8. The load will restart working once the battery voltage is back to normal
9. Built with lightning protection
10. Automatically set charge-off voltage, load-off voltage and load-restore voltage (Default parameter is under 25℃ condition, locked by CPU procedure, cannot adjust)
11. Automatically compensate the temperature of the charging voltage according to the changes of ambient temperature
12. Please notice that the controller must be connected to the battery before the solar panel; do not use solar panel supply power to the loads directly
