20A 12V Solar Charge Controller Regulator
- Suitable for solar panels up to 240W (with 12V batteries) / 480W (with 24V batteries)
- Extensive electronic protection- such as short circuit, over discharge, reverse current, over charging, reverse polarity etc.
- Types of batteries supported- sealed, gel, flooded etc.
- The solar charge controller will protect both the solar panel and the battery during use
This high accuracy 20A 12V/24V solar charge controller from PK Green is designed to protect batteries whilst charging them from solar panels. The controller uses 4-stage Pulse Width Modulation (PWM) which increases charge acceptance and prolongs the life of your battery. PWM technology can also recover some lost battery capacity.
The unit comes with Extensive electronic protection- such as short circuit, over discharge, reverse current, over charging, over heating, reverse polarity etc. Other features of this controller include LED indicators, temperature sensor, battery type switch and load "on/off" button.
The controller can work with different types of batteries such as sealed, gel and flooded batteries adjusting charging parameters for each battery type. It's suitable for solar panels with combined power up to 240W (with 12V batteries) / 480W (with 24V batteries).
Note: although the maximum allowed solar input voltage is 50V, the controller achieves its highest charging efficiency when the maximum power voltage of solar panels is close to battery voltage (e.g. charging 12V batteries by 17V-20V solar panels).
