⚡ WindyNation 10A 12V Solar Charge Controller: Waterproof, LED Charging & Load Indicators Review

Does exactly what they said. I put it on the back of the solar panel. It rained and is still raining. As a solar charger, you should allow for some waiting time. Two days 10.4 volts. I have time. Thank you 😊.

It seems that the instrument is never powered. The battery is new, the performance of the panels is normal. The battery is being charged. But it doesn't switch power for actual use. This is a type of device that doesn't allow you to track issues. (None of the others admit a diagnosis)

This is the perfect solution for me with a 100w or less solar panel. I used this charger to power an IR illuminator at night. Power lines are only activated when the solar panels are not receiving power, allowing the charger to act as a daylight sensor. I have a solar panel that uses this charger to power a 50 amp sealed battery. The mc4 connectors also speed up setup.

Bought to use as a charge controller for a solar powered trail camera. Connected to 12V lead-acid battery and Raspberry Pi with camera and 20W panel. Has been working flawlessly for a few weeks. Unlike some intended to be used as safety indicators, the load on it is always on. The voltage on the battery seems to switch correctly and both it and the sealed lead acid battery work properly down to -4F. Excellent purchase!

I use it to keep the battery fully charged on my pontoon boat. I have a small solar panel (100 watts) mounted on the back of my pontoon that keeps my battery fully charged even when we are out on the lake all day, including a stereo with amps ranging from 2 to 400 watts. I was worried that if the boat didn't start I would run out of battery and get stuck. That's no problem now. I have this because it is waterproof and I have used it on a boat. It's very limited but works great for a very small…

This unit looks good, has a large heatsink, comes with decent instructions and appears to be waterproof as promised. It has all the features you would expect, at least on paper. For some applications this will probably be a good little controller. Unfortunately, it also includes a "dawn to dusk timer" that turns off the load during daylight hours, which wasn't mentioned in the description when I bought it. . This function cannot be overridden and was a deal breaker for my application. If you…

First impression, disappointment. But I bought a cheap controller. Waterproof? May be. I can see that the sealant is not sticking to the silicone wires. I don't understand how it can be waterproof. My suggestion: if you're using it where it can get wet, install the wires down and install drip loops on any wires that go up. Can't tell yet how well the controller works, only installed a day ago. When installing, I was surprised to find that the plus is common, and the switch appears in the minus.
