SOLPERK Solar Panel Kit 20W 12V, Solar Battery Trickle Charger Maintainer + Upgrade Controller + Adjustable Mount Bracket for Boat Car RV Motorcycle Marine Automotive

I recently purchased the SOLPERK 100W Solar Battery Charger and I’ve been thoroughly impressed with its functionality and performance. I use it primarily to maintain and charge 12V batteries on my RV and it’s done an outstanding job.Functionality-wise, it delivers exactly what it promises. The MPPT charge controller is a major upgrade. It regulates the charging process, making sure that my batteries get the most efficient charge possible without overcharging . I noticed my battery reaches full charge faster and stays healthy longer compared to when I was using other brands.In terms of battery life, I’ve seen a noticeable improvement. The consistent trickle charging helps extend the overall battery lifespan, especially during off-seasons when I’m not using the RV regularly. I used to deal with dead or weak batteries after storage, but this kit has completely solved that issue.The durability of this solar panel is superior. It’s clearly built to withstand outdoor conditions. It’s waterproof, weather-resistant, and has held up well through rain, wind, and strong sun without any issues. The high-quality frame gives it a sturdy feel.When it comes to power output, this panel performs great. It consistently delivers the full 100W under direct sunlight, which is more than enough for trickle charging and maintaining multiple batteries. Even on cloudy days, it still produces a reliable amount of power.Ease of use is another major win. The kit came with everything needed for a quick setup: clear instructions, easy-to-follow wiring diagrams, and an adjustable mount that lets me position the panel at the best angle. I had it up and running in no time.The storage capacity it supports is also impressive. I’ve used it to maintain standard 12V and deep cycle batteries with no problems. It’s great for keeping larger capacity batteries topped off during long-term storage, and I like that the system is flexible enough to use across different vehicles and battery sizes.The SOLPERK 100W is a fantastic value. It's reliable, efficient, and easy to use. I’d highly recommend this kit to anyone looking for a high-quality solar charging solution for their RV, boat, car, motorcycle, or off-grid setup.

Great product that harnessed the power of the sun and charged the dead battery in my RV engine compartment. Review is for the SOLPERK Solar Panel Kit 20W 12V, Solar Battery Trickle Charger Maintainer.The battery was dead, no dash lights, no engine crank dead and the entry step would not move. My 2 house batteries were also dead. After my last camp trip in February, I carelessly let the RV batteries drain and when I tried to start months later, all batteries were drained. 6 days later, I was able to start the engine and let it run because of the solar charger. It may have charged the batteries enough to start sooner but I initially did not have the charger placed in full sun so on day 3, I moved the solar panel to the front of the RV, and on day 6 I decided to go check for life and was thrilled to be able to start/run the engine. Love the ease of use as well as the length of the cables which allowed me to try different placements and it is priced really well. I would recommend the product.

Easy to set up. Nice big solar panel. Wires and connectors lower quality than what would come with Battery Tender brand, but for the price that is to be expected. Works good.

This is for all you ATV and UTV riders, I ordered this to keep my Polaris Sportsman 4 wheeler battery charged and ready to go at the drop of a hat. Got tired of having to charge the battery the night before riding or charge my spare then swap it out. The 4 wheeler is kept in a metal shed that has no power outlet and I must always run a cord to it unless its raining.Found this on Amazon for a great price but ordered a couple of extra products to go with it, like a heavy duty mounting bracket with 4 x 3" strong magnets to attach to the metal roof of the shed no need to drill holes. I also ordered 12 ft cable for the battery charger and the most import thing was the reverse polarity connector that came with the 12ft cable. You can buy the reverse polarity connector on amazon for little of nothing but it is a must have part. I have had my 4 wheeler hooked up for over a month now and its always fully charged. This kit cost $40.00 and is well worth the investment. Hope this was helpful.

Affordable, easy to use, my battery on my camper is fully charged and ready to go.

I purchased this for my boat, as my new marina slip does not have power. I had a smaller 10W solar panel yeas ago, and this one blows it away. It works perfectly, and I tested it to charge my boat's battery before trailering the boat to the slip. It took the battery from 11.2 volts to 13.5 volts in one day and has kept my battery at 13.5 volts ever since. I use a bungee cord to secure the panel on top of the cooler in my boat. Even laying flat (without an angle facing the sun) it has kept the battery at 13.5 without fail. I feel great knowing that even if I don't use the boat for a week, my battery will be topped off. I love the lED lights that indicate charging and "fully charged."

Very nice solar panel. Used it to charge a battery powering a winch on a trailer. Battery tested 13.9 volts at standby. Great product!

Very easy to use and is working great for my Lawn Mower battery. I didn’t want to run power to my shed for a trickle charger and was tired of the extension cord going through my yard, so this works perfect!
