12V/24V 30A PWM Solar Charge Controller

$195.00 $130.00

12V/24V 30A PWM charge controller for solar panels.

2 in stock


PWM charge controller suitable for use with 12V or 12/24V solar panels up to 500W/1000W. Includes an LCD display and 6 battery type presets (LiFePO4, LTO, Gel, AGM, WET, and Calcium).

Keep the charge controller connected to the battery permanently to increase the life of your batteries. Advanced circuitry and regulators in the charge controller prevent over-charging, under-charging, and battery discharge at night. Under low or no light conditions, the voltage of solar panels can drop less than the battery, which in turn causes current to flow backwards from the battery to the solar panel. Special circuitry in the unit prevents this.
