This solar charger controller (Auto Voltage Detection) is designed for home solar power system with a solar panel rated < 170W for 12V/24 lead acid or 12.8V/25.6V LiFePO4 batteries rated <120W. It is important to include this controller in your solar power system due to following advantages:

  • Auto charge and cut-off power when 12V/24V SLA or 12.8V/25.6VLFP battery is full or low
  • Auto detect either 12V or 24V battery (must connect battery to controller first, otherwise the controller will not operate correctly!)
    • After connect battery to controller - LED Digit Display will show "0" for 12V or 12.8V and "1" for 24V or 25.6V for about 1-2 seconds, then off
  • Protect battery from overcharged and over-discharged to increase battery service life
  • Programmable Timer function to turn on load upto a max of 14 hrs after sunset
  • LED light to indicate battery storage level
  • Built in fuse to protect short circuit and wrong polarity connection 
  • Moisture proof design for outdoor use

super simple to hook up. only one negative, the trouble shooting guide could be better.

Nice controllers at a very reasonable price, that have proved to be reliable for me, so far.
Nice selection of products and prices, and quick shipping with notification.

Nice selection of products and prices, and quick shipping with notification. solar charger's instructions were difficult - noticeably translated from Chinese. the load controller ended up shorting, and i can't figure out how i might reset it (every time i connect, even though it is providing voltage, it then starts flashing raplidly).
