these are great charge controllers for solar if you have a modest setup that’s under 500 watts they work extremely good for the price and there’s nothing better until you get above $100 so it makes a lot of sense having these controllers

Thank you for your detailed feedback! We’re glad the controller is meeting your expectations for a modest setup.
