This PWM Solar Battery Charge Controller automatically manages and regulates the voltage and current to lead-acid, lithium-ion, and lithium iron phosphate (LiFePO4) batteries from the solar panel(s). It incorporates short-circuit, open-circuit, reverse polarity, and overload protection in order to ensure that the batteries are not overcharged and that power isn't discharged from the batteries to the solar panels during shaded or dark conditions and drain the batteries. It comes with USB ports to charge for your phone and other electronic devices directly from the controller.

This solar charge controller is perfect for smaller homes, cabins, RVs, and other remote and portable solar systems.

Features

  • This controller is designed for use with 3-string (11.1V) Lithium-Ion, 4-string (12.8V) Lithium Iron Phosphate (LiFePO4), or 12V and 24V lead-acid batteries. 
  • Regulates the voltage from the solar panels going to the batteries.
  • Built-in industrial master chip to control the charge and discharge process with adjustable parameters to prolong the battery life cycle and stabilize power to the load.
  • 3-stage PWM charge management with short-circuit protection, open-circuit protection, and reverse polarity protection.
  • Dual USB outputs with 5V/2A maximum power (across both outputs) can charge mobile phones, tablets, and other USB-powered devices.
  • LCD display with backlight function displays status and parameters.
  • Dual MOSFET reverse current protection, low power dissipation.
  • Easy to install and operate, suitable for home, industrial, commercial, remote, and portable solar energy systems.
  • 30A maximum input current, 10A maximum discharge current.

Specifications

  • Size: Approx. 13.3 x 7 x 3.5 cm/ 5.24 x 2.76 x 1.38 inch (LxWxH)
  • Battery Voltage:
    Lead Acid: 12V/ 24V (Auto-recognition)
    Lithium-Ion: 3S 11.1V
    Lithium Iron Phosphate (LiFePO4): 4S 12.8V 
  • Input Charging Current: 30A. The maximum panel output current should be about 25% less than the controller's maximum input current rating, hence the maximum solar panel current should not exceed about 22A
  • Maximum Discharge Current: 10A
    Internal power consumption: ≤10mA
  • Battery Types/Voltages
    • B1 Lead Acid / 12V/24V (Auto-recognition)
    • B2 3S Lithium Ion / 3.7V * 3 = 11.1V
    • B3 4S Lithium Iron Phosphate (LiFePO4) 3.2V * 4 = 12.8V
  • Equalization: 14.4V* (B1); 12.6V (B2); 14.6V (B3)
  • Over-discharge Protection (Discharge Stop): 10.7V* (B1); 9V (B2); 10V (B3)
  • Over-discharge Recovery (Discharge Reconnect): 12.6V* (B1); 10.5V (B2); 12V (B3)
  • USB output: 5V/2A
  • 12V batteries should be used with solar panels capable of generating 18V-23V
    With 12V batteries, the maximum panel voltage must not exceed 23V
  • 24V batteries should be used with solar panels capable of generating 36V-46V
    With 24V batteries, the maximum panel voltage must not exceed 46V
  • Maximum Power Input: 12V: 360W (MAX), 24V: 720W (MAX)
  • Operating Temperature: -35 ~ +60℃
  • Storage Temperature: -35 ~ +60℃

Operation:

  • Make sure your battery has enough voltage (typically 10V or more) to power on the controller and to recognize the battery type.
  • The battery cables should be as short as possible to minimize losses.
  • Connection:
    • Connect the battery to the charge controller first. The controller's LCD should turn on. Do not proceed if the LCD display does not turn on!
    • Connect the photovoltaic module to the charge controller.
    • Connect your load (the device(s) you are going to power) to the charge controller.
    • Reverse these steps when disconnecting or uninstalling the controller.
