Overviews
This is a new series of intelligent multi-purpose solar charge controllers. It's equipped with explicit LED for your choice. While meeting functional needs, it also offers user-friendly installation and operation. All in all, it's a popular high-efficient product.
Function features

1. Vivid LED indicators show system battery capacity, charging and discharging state of battery.

2. Protection functions such as overcharging, over discharging, overload and reverse connection.

3. PWM charging increases charging efficiency by 3% to 6%, compared with non-PWM charging.

4. The parameters of charging and discharging are preset, so no need to adjust the parameters. (Special parameters need to be advised in advance.)

5. USB output function.
