   Highly recommended.
   Highly recommended. I have it charging the battery of my emergency generators, very good and it keeps the batteries charged without any problem, highly recommended. I bought it a long time ago and installed it just a month ago, due to longevity I cannot say anything about it but it works perfectly with its voltages and charges of the generator batteries.

   Purchased 2 for my Utility & Dump trailer 30W chargers
   Purchased 2 for my Utility & Dump trailer 30W chargers, but have yet to install on my trailers. I’ve been using them on my lawn tractor, Zero turn and log splitter for about a month now to maintain the batteries and I’m pleased with how good they work. They are easy to move from one to another by just unplugging from one and re-plugging to another. Seems to charge well enough even on cloudy days. They are keeping my batteries at 13.4v to 13.6v. I’ve decided to purchased 50w chargers for my dump trailer because I want more charging capacity for the larger batteries because the batteries are discharged when in use.My only complaint is that it would be nice if the adjustable angle mechanism had a spring loaded de tent (like on a walking cane) instead of the bolts and wing nuts for angle adjustment. Also, would be nice to have a long and narrow panel to accommodate location under the header of my dump trailer. Wattage size of 50w to 100w with a length of about 5 foot and a width of about 12″ to 16″

   Quality build
   I bought 2 of these and just put them together. I gave 4 stars because I’ve not had them working long enough to rate how well they do.I must say though that if function follows form on these then they will do very well.They are very well built in my opinion, the frames are sturdy with nice powder coated brackets to put them into, the hardware for the set up is easy to work with (I put them together with no tools) I will use some tools when attaching the brackets to something permanently, a screwdriver most likely.The wiring setup is truly idiot proof with a nice long wire coming off the panel and terminating in nice plug. I was surprised to find 3 options for connecting to a battery one with nice quality spring loaded clamps, one with ring terminals and one with bare wire ends. These wire ends were “tinnned” already which means they are solder coated.Over all the form factor of the product and it’s related components impressed me and I have high standards for these sorts of things… What I received was better than I expected.

   Easy Installation
   Easy to install. I am using this for a garage with no power where I store a car over the winter. Easy to install and keep the battery charged. My only complaint is the description did not tell ne how long the charging lead was. It would help to know if you need an extension to reach to the car battery.

   Solar charger
   Bought this back in early April, it is now November. Mounted it to rear of my pontoon boat and used it all summer. This is just a 30 watt trickle charger. I got 1.5 to 1.75 amps out of it on a really sunny day and around 1 amp on an overcast sky. It kept my boat deep cycle battery conditioned and fully charged all summer. This one fits perfect off the back but I wish I could fit a bigger one. The mounting frame is pretty beefy, and the whole thing has a sturdiness to it. It looks good and I really like it. It has a nice aluminum type finish and blends good with older pontoon boats. They include both wires with alligator clips or terminal eyes for the battery connection. It’s so nice to go down to my dock and fire up an old motor with a fully charged battery. I like this company’s designs. I hope they keep making good stuff. After I got this, two other boats copied me with the same one🤣.

   Sadly disappointed, failed on first use. Read to the end update.
   Bought it mid November to keep my pickup charged while away for xmas. My previous one 10w sometimes struggled to keep my battery charged if weather inclement.I installed it checked it’s output. All seemed good. Parked the pickup with the panel on the dash in Florida.Came back yesterday to a total flat battery. The battery was new (3 months). Checked the unit and it has no output. Very disappointed. Used once and it died, of course no warranty, its now 2 months old and used once.UPDATE!Due to pressure of work I did not contact the company or amazon to express my disappointment.HOWEVER, the company must check their reviews and contacted me out of the blue. After replying to their email concerning technical info etc. They have now sent me a new F.O.C. panel which I plugged in this morning and is now working fine. As far as I am concerned this is great service, and going beyond the call. I’m very impressed in them checking reviews to make sure their customers are happy and contacting me when they realized my disappointment immediately. Thank you Mason and the staff at Sunpower for solving the situation. Incredible aftersales service!

   Doesn’t Work & Not good customer service
   I purchased the 30W Solar Charger, out of the box the charger would not produce power, I checked both sets of leads, neither would work to detect the Battery, I hooked my fluke tester directly to the leads coupling with the panel facing directly into the sun and it was not producing any power (No voltage). All it will do is the SOR flashes Red to Green on the charge controller. I got online to try to contact the manufacturer, no phone number listed, (1st indication that you should not be doing business with them), so sent Emails to them, (crickets). I finally had to contact Amazon, then Suner Support got back to me, by this time I had to return to work, then they want videos of what it is doing. In short, I would have not given them 1 star, but I thought if I didn’t my review would not get posted.
