Efficient 50W Solar Panel Kit with Upgraded Charge Controller – SUNER POWER Mono Crystalline Panels, Waterproof, and Versatile 12V Solar System for Car, RV, Marine, Boat, Trailer, Off-Grid Applications Review

Started with charged battery. I connected everything but I can't get the charge controller to work properly with a 10 watt LED bulb connected. I unhooked everything, connected the light directly to the battery, it works fine. Plug everything back into the charge controller and the light stops working. The solar panel works great, but if I missed something in the instructions, then the controller is junk. The controller will only charge and wait for the battery.

I bought this for a Mighty Mule 500 gate opener. It doesn't come with a mounting bracket so I used the bracket from a 5w panel I bought when I was installed the opener. I didn't realize it until I started working on it, but the Mighty Mule control box can handle up to 30W without an additional control box, so I didn't have to buy that particular group, although the SAE connectors are worth it. It really was a complete shutdown and swap, and the new solar panel charges everything perfectly. Very

I attached my panel to Renogy Z mounts and attached them to a 16X20 plywood corner on the side of the snow blower roof. The controller is attached to an internal ceiling beam and seems to regulate the battery well, I let it do its job undisturbed. As with all these products, make sure the battery cables are separated to avoid short circuits. I rely on my plow to be ready when I need it, and a well-charged battery lasts a long time. This system works well for me.

Pros: The panel has a nice aluminum frame, the voltage regulator looks nice and everything came ready to go with SAE solar connectors. Cons: The documentation was written in Chinglish. Bad mix of Chinese and English, hard to understand at times. The 3 status LEDs on the voltage regulator were placed pointlessly. IE: loading = red. The worst thing was that the solar panel was defective when delivered. This is the third solar panel I've bought to charge RV batteries and I always use my VOM to…

I bought this solar kit to charge 2 small 12v batteries in my kids 12v cars in my shed. I connected them to use the SAE connector so I could use the car charger in the garage (worked perfectly for 2 years) or use this solar charger so I could take them out of my garage. Yesterday I swapped the charging cable from one car to the other to make sure they were both charged. This morning my 5 year old went for a walk and found them both dead. Upon further investigation the SAE extension cord and all

I hooked this up on July 1st - 90 degrees, almost no clouds. This gave 0.81A x 20V = 16.2W. * I never expected Revain's affordable solar panel to perform 100% of the description so to be clear I'm not complaining, I am enthusiastic about this panel. So 5 stars. It takes 5 seconds to set up and is mostly foolproof. If you want to play around with the luminous flux, set it to 120 (and that's not foolproof). I use this for auto camping (I wouldn't call it glamping but others may disagree). I have…

I removed the panel, put a meter on it, got 19.87 volts. Controller plugged in, yellow light on (minimal docs doesn't explain what that means) Controller output was only 4.3 volts! Connected to the battery for charging, the light went out. Numerous emails to the company (they don't have a phone!) went unanswered after five days. Item returned to Revain. Revain refunded me on the day UPS received the excellent package, even though the money was on a Revain "gift card" and not returned to my…
