Customer Reviews for VEVOR 30W 12V Solar Panel Battery Charger, Solar Battery Trickle Charger Maintainer with Intelligent MPPT Controller & Adjustable Mount Bracket, IP67 Waterproof for Car Boat RV Motorcycle Trailer

I was plkeased with the size oif the solar panel, However, the instructions are very vague. It does not show you what wires or cables are to be connected to what item.

OnlyDo not buy any of these solar panel kits that comes with a MPPT Controller if you are needing to mount it on a trailer that has no dry storage. The MPPT Controller is NOT IP67 RATED. It has to be mounted in a dry place that can vent. I purchased this unit for a gooseneck dump trailer that does not have any dry storage compartments because the item description said IP67 rated. The only thing that is IP67 rated is the solar panel. I would think that all solar panels would be IP67 rated because they have to be outside and are designed for the weather, so I thought the IP67 rating was for the MPPT Controller. But buyer beware, IT IS NOT!!!!!!! Now, I have to return it and look somewhere else for a unit that is completely weather proof.

The overall unit is excellent. the maintainer and controller work great. the stand for the larger panel is not sufficient. i have to remake a more solid stand to attach to a high point. it seems very flimsy and moves around quite a bit. it should have a couple side/bottom sliding anchor points.

Panel and Maintainer works good. The wiring gauge is very minimal and the provided clips broke the first time install. A heavier gauge wire and better alligator clips, would get a 5 rating.

This solar battery charger was a breeze to install, but nothing in the kit feels like a quality product. It all feels cheap and easily breakable. I'd recommend that you install this in a weather proof location, shielded from elements or anything that could bump it. A rogue basketball will absolutely devastate this solar panel, so make sure it's in a safe location. Although the instructions aren't great, it was easy to figure out. 1. Install bracket on solar cell and place in stable location 2. Connect battery to regulator 3. Connect solar cell to regulator I installed this on a teenagers car who isn't ready to drive yet. While I have good intentions of going out to start the car and let it run to charge every month, sometimes months go by that I let it go, including over winter. The car isn't parked in a place where I could use a normal battery tender without running a long extension cord. Preferring not to do that, I bought the VEVOR Solar Battery Trickle Charger. The instructions say not to install this on a dead battery. So my first step was running a 60A fast charger on it for 30 minutes. That was enough to get the car to start and for the battery to read 12.6V. After that, I shut it back down and started the installation. First impressions of the solar panel: Attaching the bracket to the solar panel lead to my first disappointment. The bracket attaches with small bolts that push through the frame and lock in place using a wing nut. First problem - there is a bead of glue holding the photo cell to the frame that gets in the way of the bolt. When tightening the wing nut, you're constantly pulling the bolt into the glue. This means you can never really get enough tension on the wing nut to tightly hold the bracket. I ended up getting a hand tool and tightened the wing nut past the glue. Second problem. I felt like I was stripping or, even worse, stretching the threads on the bolt. Eventually I gave up on tightening the bracket for fear of stripping the bolts. At t

I can’t seem to get the controller to charge my lithium battery. And I can’t locate a manual for the charge controller.
