45A PWM Solar Charge Controller 12V/24V Auto-Detect Regulator

Shot Description

In PWM solar charge controller, the current from the solar panel tapers according to the battery’s condition and recharging needs. When a battery voltage reaches the regulation set point, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery, yet the charging continues to return the maximum amount of energy to the battery in the shortest time.


1. High quality, reliable and economically priced charge controller
2. PWM charge controller is a good low-cost solution for small systems
3. Electronic protection: Over charge, over discharge, overload and short circuit protection
4. Tiny self-consumption (2mA-12V/4mA-24V)
5. 3-stage charging algorithm, impulsive charge, bulk charge, floating charge
6. Built-in light sensor, suitable for a periodic discharge system such as solar street lights, solar pumps etc, the solar panels
7. 1 Year Warranty
