Great product
This solar charger works exactly as expected and feels well made right out of the box. The 30W panel provides steady solar power, and the 10A MPPT controller does a great job keeping my 12V battery topped up without overcharging. Battery life has been more stable since installing it, especially on my car that sits unused for days. Instructions were clear and easy to follow, and the adjustable mount made setup quick. It’s lightweight, portable, and handles outdoor use without issues. Overall, solid performance and good value for a reliable trickle charger.

Easy to use and install
I purchased the SOLPERK Solar Panel Kit 20W 12V, Solar Battery Trickle Charger Maintainer to charge the battery on my lawn tractor, which sits in a shed without electric service. So, the battery didn’t seem to maintain a full charge between uses and sometimes wouldn’t turn the engine over. I installed this yesterday to help maintain the lawn tractor battery in full capacity. The installation is pretty simple, with a bracket to hold the solar panel provided. Just a note, the bracket can only be mounted in a horizontal position to support the solar panel and provide directional control for the panel to face the sun. Installing the bracket vertically, will only allow the solar panel to be turned left and right and will be perpendicular to the sun if mounted on a vertical post or wall. There is about 6′ of wiring to the controller which connects to the panel. The controller requires no programming by the user. Connect the controller to the 12V battery (battery clamps provided with unit) then plug it in to the solar panel and three lights will tell you everything. The blue light (on top of the others) tells you the panel is in the sunlight and providing normal voltage. The second light is red and will tell you that it is charging the battery. The third light (green) appears only when the battery is charged, which means the battery has 14.2 volt charge. It comes with a set of wires to actually screw down on battery posts. So far, the unit seems to be working and has charged my 12V battery fully! No need to remove the connections when charged, as the controller will prevent it from overcharging the battery. I don’t know about longevity of the product, the controller is supposed to be waterproof but I keep it inside with the lawn tractor. Other than keeping the solar panel clean with a damp towel, and the battery clamps clean, there isn’t much more maintenance required, the instructions say! So far, I do like the unit and being able to keep my lawn tractor battery at full charge! Easy installation!

I purchased with the hope that this charger would keep my car battery charged over several months while I was away from home. I have now used it twice, both for two month periods where the car was parked under a carport. Even though the charger was not in full sun, it has worked and the battery has been fully charged each time on my return.
