Gamistar 40A 12/24v Solar Charge Controller

Features: 

• Backlight Design - With Color Backlight display function the user can clearly check the working status in the night, meanwhile with very small power consumption
• Input current & Voltage display - User can see the input current and Voltage from the solar panel, the function helps users to test the quality of solar panel(current x voltage = power)
• Output current display - When 12V or 24V/48V load connected to the controller works, the screen show the output current, this function helps user master the working status of the load.
• 4 pcs of USB Output - This controller have 2 groups of USB output(4pcs), each group with 2A current which able to charge 4pcs of iPhone 6S at the same time.
• 12V/24V/48V auto voltage distinguish function 
• Over-charge, over-discharge, short-circuit protections, to ensure system safe and prolong battery life.
• With battery temperature compensation, ensure best charge status in different environment.
• Three stage charge mode: strong charge, constant current, floating charge intelligent control
