I purchased 2 of these, one for my generator and one for my boat. I have a different controller where I can monitor the actual voltage, but connect it to this panel for both uses. The panels are about a year old. They are mounted outside in the weather and have worked well. For my generator: it has kept my gel battery topped off and have strong starts every time. For the boat: It has supplied enough power to keep my 890CCA battery maintained during the winter and when the boat is not in use during the season, I have kept it plugged in and maintains a full charge. Given my boat battery is fairly big, this panel has worked fine. When I place my battery tester on it the tester confirms a 98% charge after winter. Pretty impressive considering the size of the battery and only 10W out from the panel. The panels get direct daylight for about 5 hours a day and then are in shadow. The controllers show charging still in the shadow so direct sunlight is not exactly needed but if you want to maximize your capabilities, I'd say make sure they have enough direct light for at least 1/2 of the day. Otherwise, the shade doesn't appear to hurt it any. Cloudy days still produce a good charge. Going to purchase another soon for my father's new generator that I am going to buy for him.

This is a very well made solar charger. The only problem I had was that the polarity is backward from the other one I have. My bad for having assumed that the same connector would have the same polarity, but I guess IEEE standards don't trickle down to this level of engineering. No matter, once I reversed the polarity of the solar panel wires connected directly to the battery on my RV everything worked like a dream. It's a good value and should add years of life to my RV battery. I would recommend this unit if you're looking for a weatherproof outdoor-rated solar-powered 12v battery trickle charger.

I have this to keep a 12 volt lead-acid battery charges that powers lights in storage units that don't have electricity. So far it's been working great. ****One WARNING âš ï¸ the plug on the output side to the battery is the standard plug most all tricked chargers (like a Battery Tender) use HOWEVER the polarity on their plug is the REVERSE of all the standard plugs. So keep this in mind if you're going to use it on equipment that already has a charger pigtail installed. ****

This product was easy to install in my nephew's shed. I installed this product to keep his riding lawnmower battery charging while not in use. So far it is working quite well and would definitely recommend this product.

I got this charger to maintain the starter battery on my backup generator. Works great. It's not designed to a rapid charge, but a slow trickle charge. It's small panel size is just perfect to mount to the top of the generator housing cover. Cables are long enough to reach. Quick connect connectors make installation a breeze. Well worth the money for what it does.

I use this to maintain the battery in a lawntractor. The shed housing it has no power, but plenty of sun exposure works well for maintaining while sitting 3 months over the winter

I bought it this April because of could in case of a power outage, I finally put it all together 2 months ago, one day my battery dies, the controller shows yellow light charging. But it is really not I test the voltage that it is trying to charge it is zero from solar.sure it powers light saying charging. but zero charges. I move solar still nothin', maybe bad wiring or maybe bad solar panel. something. I suggest buying all things you need and test them right away. I got a bad one, and I m out the money. NO tech number, sure it says tech support, but it's all lies, I search google, amazon all over for the last 2 months, I decide to call it quits, and write this bad review. I am out 65 dollars, and wasted time searching and putting it all together. I suggest trying other companies they show a tech number and have a website or something to help people, I feel this is all made up and I bought garbage. Well, lesson learns 65 dollars wasted, and over 10 hours trying to get it working and searching for help. But there is no one to help. So give up like me, and do not buy this product, and found a company that has a website and a tech number.Can you send a new one? It never charges fast enough I think the panel is bad. I would like to try a new one. Please send to 306 Dawes st, WI 54901

There were no section attachments in my box. So I can’t speak to it.However the charger has been amazing. I recently replaced my 2 RV batteries in my travel trailer and thought this might be a better method to keep the trailer charged, rather than have it plugged in 24/7 and checking the acid levels every couple months. So far in the week before a trip the batteries stayed at 100%. Camping I brought my generator but never had to use it. Keep in mind I’m pretty economical at battery usage. Only using the pump for water. I did shower, dishes and of course coffee. Showed minimal battery loss in the am and always fully charged again in the afternoon. Best purchase ever.

This panel worked great out of the box. I had bought a cheaper version ($31) advertising 30 watts and it could barely deliver 2 watts under full sun and it was returned and refunded. This unit supplied 18 V at 150 mA on a fully overcast day. Controller is very useful as it indicates when there is sufficient solar radiation, charging, and fully charged. At fully charged status it puts out 13.3 V to keep the battery topped up. I would buy this solar panel again.

Ok, first things first. This, or any other 10W panel, WILL NOT recharge your big dead battery. For that choose something bigger, like at least 30W. What it does do is keep your battery from discharging over time in a vehicle you don't use often. Just like the description and instructions say!It's super simple to hook up but if you have a question like I did, tech support replies within hours.Great little unit. Would definitely buy a sefond one of I had another vehicle that's parked a lot.

I own a pressure washing company and I use a marine battery to run my soft wash pump and this solar panel keeps the battery charged and maintained at a charge so I'm happy with it!

Bought for my trailer and it’s not working at all! I do see the light on the controller come on but battery is not charging

got it and returned it on the same day. Realized it was a 20 watts when we are looking for a 100Watts. We must a touched the wrong button. Return was perfect
