  • Rated Discharge Current: 20A; USB Output Voltage: 5V/3A; Battery Voltage: 12V/24V auto. Adjustable power rate with dual USB ports; 3-Stage(Bulk, ABS, Float) charge management and 4-Stage PWM charge
  • Functionality: Equipped with industrial-grade STM 8 microprocessor to control the charger and discharge process and it has reliable battery to charge and discharge period management
  • Mutiple electric protection: over-current and short-circuit protection, inverse connection protection, low voltage and overcharge protection
  • Good Heat Dissipation: Dual mosfet reverse current protection, low heat production
  • Easy to use: Comes with a display that can clearly indicate the status and data, it can be conveniently switched modes and parameter configuration, suitable for home, industrial, commercial etc

The product can automatically manage the working of solar panel and battery in the solar system. It is easy to set up and operate.
For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically (LCD will be unavailable at the same time).
Change the default setting of the solar controller, requires:
1. Disconnect the solar panel
2. ensure the remaining voltage of battery no less than 12V


<1>Please keep it in a cool and well-ventilated place to maintain good heat dissipation.

<2>the regulator is only suitable for lead-acid batteries: OPEN, AGM, GEL, not for nickel hydride, lithium, ions, or other batteries.

<3>Make sure your battery has enough voltage for the controller to recognize the battery before the first installation.


Warm Tips: Only voltage reading in the screen of the solar controller, no amps or amp hours.
