Use this to charge my rv batteries while out camping, bought an extension pig tail so I can just set it out side and move it where the sun is shining and put it back in the camper when I don’t need it.What more can be said, it works.????Pretty nice product, fair build quality. Only issue is -- you need to know to connect the battery wires first, and then the wires to the solar panel. If not done in this sequence the charger will not work.This arrived with defective cabled plug as I noticed the controller would not detect the solar panel. Luckily I had a spare cabled plug the controller now detects the solar panel. The 50 watts keep my battery topped off and charges fairly quickly when tools are in use by way of the inverter. Overall a good product would have earned 5 stars if not for the defective cable.The frame where the stand bolts to the frame was bent badly on one side. I straightened it as best I could and assembled the stand. Other than that we're pleased so far, will post more after it has been charging for a day.Easy to hook up and has worked wellAfter reviewing several panels and determining that I needed one with the capability of being weather resistant, I decided to purchase the 20W SOLPERK Solar Panel Kit 20W 12V, Solar Battery Trickle Charger Maintainer.Initially, I read various concerns about overcharging the battery were stated on other SOLPERK reviews, as well as some hardware issues, but as this one had no reviews at the time, I thought I would take the chance to use this panel to charge a 12V battery that I use to provide light to my stand-alone shed.Installation was straightforward and aside from finding a way to thread the wire from the roof of my shed to the battery, there is nothing complicated about the installation. (I did create a bracket to prevent damaging the roof, and would recommend that approach to prevent inducing leaks on a shingled roof.)After set-up, I didn't see a green light (indicating complete charge) on the battery indicator, but since I hadn't charged the battery in a while, I thought I would give it time. I did monitor the output of the solar cell (roughly 14V depending on sun exposure) and noted that with no load, my battery was just about 12 volts. After a day, the voltage on the battery popped up to about 12.4V, but I still had a red light on the battery charge indicator. By day 3, the battery light was green and the battery was at full capacity.Testing a week later, I drained the battery a bit by leaving some lights on for about 1 hr (12 V LEDS). The battery charge light was red for a period of time and then went green again. The battery had maintained full charge.At this point, I've had the panel connected to the battery for about 2 weeks and all seems well. Should I see the battery overcharge or diminish in capacity, I will update my review, but until that time comes, everything seems to be working well.I had ordered a different brand from a different supplier where the controller didn't work. So I odered this one. I could tell immediatley it was better quality in not only the solar panel, but the controller was metal instead of plastic, and has an extra connection for a light. Although I found out of 2 I ordered, the solar panel LED indicator light doesn't seem to work. However it does chaarge, and operate correctly otherwise.
