Solar Panel Kit 20W 12V Solar Battery Charger Trickle Maintainer

I bought a new Hydraulic Dump Trailer and needed a way to keep the battery on the Hydraulic Unit charged, since I park it away from all the plugs I have. Every time I have checked the battery, it has had a full charge, even in the cloudy days. It doesn't take much sunlight to keep it charged. The wiring is simple and the installation is super easy, especially with the instructions included. The length of the charging cable that came with it is very long. I am thinking of ordering one for my lawn mower and my motorcycle. The charging panel that tells the charge on the battery is really easy to understand also. I will give it the 5 star recommendation.

This Solarpek 20W kit is built around a functional monocrystal cell and a smart MPPT controller, which together deliver consistent charging performance as expected. They clearly prioritized functionality over durability, but the trade‑off works; the cell operates around 20W and the controller does its job. I ran it for a week in southern Arizona with mixed cloudy and sunny days, and at the end of the test the battery was sitting steady at 13.3V. For the price, it’s a straightforward, effective product that does what it claims.

First let me say it does the job where it comes to float charging my 12v generator battery. All the lights worked as they should, but starting a couple days ago, the only light that lights is the one says "in the sun". The "charging" and "charged" lights have quit working. I tested the unit with my meter and it still outputs the expected voltage when in the sun, so it still works that way. I just can no longer tell when my battery is fully charged unless I put my meter on the battery. I've had the solar charger for four weeks. I've unplugged the cables several times and replugged...no change.

Happy with the purchase. It turns out that the controller is self-regulating and does NOT need a fuse on the line.Customer support was prompt and knowledgeable.So if you currently have a battery cable with a fuse for charging, you don't need it with this setup.

Easy to hook up and a fully charge my ATV works great . I have no electricity in my pole barn and now I can steal my quad in there and charge it at the same time.

This works great out of the box. For the price I was a little concerned, but now I am very happy. There are good instruction for operation, and when I gave it atest on a cloudy day it had 14.6 V at the battery connections. The battery was dead and reading 0 volts when i started the test, 2 hours later, through the clouds, and the battery was at 9.6 V. Can't wait to give it a try on the camper to see how much it will charge the batteries during a full day.

Works great, I have it mounted to my tracker 16X48 and it perfectly maintains my battery

So far so good. I don't drive very far so I use more battery then my alternator re-charges, so eventually I would end up having to jump start my car. So far It works great. Took @ 2 weeks to get the full battery light to come on. The set up is super easy. I wish it had suction cups to attach to the window but I just set it up on the dashboard. I live in sunny California so 20W works if you live in a less sunny area and you have a similar issue you may want to step up to a bit higher wattage just in case unless you don't drive daily.

Great product with great pricing. Will buy again. Highly recommended seller.

Works as stated. Good value. I use it to trickle feed my motorhome starter battery while it is stored. The cables are a fair length for most; however, I did need to extend mine because I wanted it on the roof of the motorhome where it was in the sun all day and not sitting on the ground. It does come with a handy bracket that can be used as a stable stand, or for mounting somewhere. It also has a controller to make sure it doesn't over-charge. I'll see how it goes for a few months and update the review if need be.

Came to date is supposed to come, nothing was damaged, exactly what I wanted, works well

Very nice unit that works as expected for a good price.

Good
