Review on 🔋 HUINE 20A 12V 24V Auto IP68 Waterproof PWM Solar Charge Controller Solar Panel Battery Intelligent Regulator for Solar System Caravan Boat - Enhanced 24-Hour Working Mode by John Faxon

No complaints. I bought it for a small solar build and needed a small controller. It works great and I like that it shows what functions are running on the system. To update. I had a problem with one of the batteries I ordered, it didn't protect against overcharging and got more than 15V from the controller. HUINE technical support responded immediately and helped solve the problem! I was very impressed by their willingness to help. It's the perfect size for small portable builds and you can rest assured that it's a product you can count on as the company is quick to help if there's an issue. Highly recommended!
