🔋 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 Review

The controller was tested before installation and works perfectly. It also serves my purpose when mounted on an RV in a non-pressurized location next to the chassis batteries. This allows for a larger solar panel than the factory one, allowing for better maintenance of expensive batteries. Durability and reliability must be achieved with optimal loading. Newmar offers a small 10-watt panel without adjustment, which is not sufficient in most cases.

I bought this to replace a cheap PWM controller as I wanted it to be waterproof. I agree with the previous review that the wires are a bit flimsy. The indicator lights could be a bit brighter, and I'd like to be able to turn them off when not in use (e.g. at night) to reduce ghosting. I connected in parallel with another cheap PWM controller and this controller and this controller has a much better charge according to my multimeter. It also has reverse polarity protection. The price is right…

This is a very good block, everything is epoxy inside and probably weatherproof. When I use it, the battery has been draining at night and it doesn't seem to stop protecting the battery. (BAT LED flashes). It doesn't charge automatically in the morning. I have to reset it every morning and it doesn't work for my "automatic" system. Would like to try another.

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…

I have 2-10 amp and 3-20 amp these charge controllers, they are the best charge controllers I have bought in the last 10 years, they are small, compact and one hundred percent waterproof I love how the electronics are sealed in a silicone based material similar to what was used to seal electronics for car parts in the 1980's. Years. I also like the fact that these charge controllers are waterproof and can withstand both high and low temperatures. It is very easy to install these charge…

I use these controllers to protect my car battery powered pan/tilt/zoom cameras which are powered by a 100 watt solar panel. The compact size is great for my applications. I have it in a case but knowing it's waterproof is an extra layer of protection. I've used several other controller configurations, some with voltage ratings and different indicator lights that are more draining on the battery. I've also used controllers with on and off buttons where if the controller shuts down due to a low…

I bought one for a "solar generator" DIY project. This charge controller is good for some use cases and really bad for others, so make sure you know what you're getting before you commit. Otherwise, skip this and choose Renogy. This HUINE device is very small. According to the ad, it's epoxy filled and most likely waterproof, or at least durable. However, I wouldn't intentionally submerge it. The wires are also very small and thin. The wire can handle a 20A surge, but I don't think it can…
