I now own two of these and I still can't get the eco-worthy controller to show only LED 1 which indicates a sealed battery. It always shows LED one and two. The directions are confusing or inaccurate. This controller cannot recognize a battery for what it is. Again I have purchased a small MTTP controller that has no trouble whatsoever identifying what my battery is.___________________I gave this a five stars because it seemed unfair to ding my review over the fact that the controller that came with it to proved to be unworkable. After 6:00 or 7 readings of the directions I was unable to make the controller recognize and AGM battery. The AGM would go under sealed battery but it kept staying on two lights which meant that it was either a lithium battery or a gel battery. You can't run an AGM battery on anything other than sealed or AGM. For that reason I had to move to a tiny MTTP controller that worked instantly and made it very easy for me to link the battery with the solar panel.I think that it's a very nice system and I'm using it to trickle charge and AGM battery over winter. My plan is to buy another one of these and set it up in the same way to trickle charge over winter a typical sealed battery.Here is something you'll really love. I set this up approximately 24 hours before hurricane Helene hit the mountains of Western North Carolina. The solar panel was set up on a 4x4 post with a 2x4 support that formed a cross. The cord on the panel is very long and makes connection into a outdoor storage cabinet very easy. I then connected some green covered ground wire to a 4 ft piece of rebar next to the 4x4 post. I then stapled the ground wire such that it was not going to pull on the solar panel. The result was very pleasing. It's survived 40 to 60 mile an hour winds.I do hope to figure out why I was unable to program the control panel that came with it.

I have 3 of these and they all have worked perfectly for a couple years in all weather, extreme hot, cold ice etc. you obviously need direct sun for optimum performance.

This is the second of two of these panel kits I've bought. The first was several years ago to provide lighting in two Conex storage containers. I bought this new one for an out door lighting project.The panel and two 12 AH batteries are lighting our sign on the road and a set of "mushroom" lights on a fence. That part works great. The lights are controlled by a dusk-dawn switch (white cube in the photo) and stay lit all night. The panel provides enough current to fully charge (~14V) both batteries by the early afternoon.The charge controller is junk. Both this one and the previous one would not output to the LOAD terminals, regardless the charge state of the batteries. The controller worked on this new panel for about five minutes before the LOAD light went out and never came back on. A multimeter confirmed that there was no output from the negative terminal of the LOAD terminals.I have a better charge controller on the way. It's the same one I used previously.Just figure on buying a decent quality controller (The wiring kit, aside from the wires installed on the panel, is also pretty much useless.

Everything worked together perfectly. I added a small ceramic heater and LED light to the setup and I’m ready now to install it in my small greenhouse and start my seedlings.

I used with some old batteries that were not strong enough for their original use (gate) and hooked to a set of cheap 12v led light fixtures in a woodshed. I plan on using it as place to put not great, but not dead, batteries to get a bit more usage from them before disposal. The batteries I am using can run the two lights for hours even though they are not good enough to run my gate for more than a cycle or two as an example. I mounted a toggle switch by the handle on a barn style door. It works great so far. In winter it can generate enough to run the two lights (12V 1A) during the day without the battery. If it continues to work well I may add one to my riding lawnmower as battery maintainer !

I had previously used a 10W solar panel for this but it did failed to provide adequate charge. This solar panel is keeping the battery charged so that I can use the electric starter when needed.

Good construction and fits perfectly for my chicken coop. I was looking for power so that I didn't have to manually open my chicken door every morning. The Harbor Freight DIY system I put together, simply wasn't working. This had done the trick.

I had been using a mains battery charger to come on for an hour each day to charge the battery of my Jaguar XK8 in the garage, but didn't like the idea of it, so looked for a solar alternative. Have now used the panel for three weeks and it is superb, although we have had little sun, the battery shows a constant 12.8 volts all the time. The charge panel shows a solid green led, showing its charged. I put it onto a flat battery and the led blinks as it charges until it reaches 12 volts, then holds it at that. On the down side, the instructions are very basic, and the led unit, I had to put Velcro on the adhere to the wall as it does not have a fixing itself, and the panel itself has no holes so had to make my own brackets, but in operation its superb.

Purchased this solar charger unit to keep RV batteries topped off over winter and it has worked fantastically. Batteries are full and the automatic charger works great. 10/10 would buy again.
