    Another great ROCKSOLAR product!

    Got for DIY solar fence charger. Put into a weatherproof box and so far no issues. It is using a 30w panel to maintain a 12v deep cell sealed battery.

    Working perfectly! Thanks

    Very easy to install. Working perfectly with 200w of solar panels. very happy to use this solar charge controller.

    Awesome pwm charger .

    I used this controller to charge my 16 ah 12v lifepo4 battery with 2 100-watt solar panels in parallel. Runs my DIY swamp cooler all day off the grid. Completely awesome, thanks ROCKSOLAR for another fine product. it's perfect for what I needed.

    Works great! for my complete solar setup.

    Highly efficient solar controller. provide outstanding solar outpur even in the very cloudy day.

    Easy to set up and use

    I am replacing my camper battery with LiFePO and bought this to replace the existing solar charge controller. Thus far, I love it. It supports Lithium batteries. Since the controller is installed in a cabinet it's working just wow. I'm really glad I purchase this controller. The price point is also excellent.
