Bests & Worsts Reviews from Amazon

Installed this system on my Toy Hauler RV. It is keeping the two batteries charged very nicely. We can watch a movie at night, and the batteries are fully charged by the next evening. I suspect we could watch a couple of movies, but I haven't done this yet. We use LED light bulbs throughout the RV to reduce consumption. I wish more people would go solar and use their generators less. Solar won't power the microwave or air conditioner, but it powers everything else. Some people complain about the controller, but I think it does fine. The complaint is that it doesn't have a meter to show voltage or current. In my opinion, you only want this in the beginning to see how efficient your system is. The controller has LEDs that show when it is charging and when it is in maintenance charge mode (batteries full). I have an inexpensive volt meter that plugs into the 12 volt outlet. Good enough for me. Do not buy the huge fuse holder and 100A fuses that appear as "Items other people bought with this." The correct fuses are 15A and 30A, and you can use standard automotive fuse holders. There is an inexpensive meter that appears when you purchase this, and I recommend that you fully read the instructions and develop a plan before buying it. This meter can only tell you what is happening at the point of installation. For example, some people install this between the panels and the controller (shows panel output), between the controller and the batteries (shows controller output), or between the batteries and the load (shows what the appliances are actually using from the battery). In my opinion, the last application is the only one I care about on an ongoing basis, and the installation for this application is independent of the solar install. Also, take the time to look up the recommended roof attachment procedures for your type of roof. I have an EPM roof, so I looked at the manufacturer videos for attaching a fan to an EPM roof and used those as a guide. I was surprised to learn that butyl tape is the first line of defense and the self-leveling caulk was the second line of defense. If the roof leaks, dry rot will likely follow, and that can be expensive at best or ruin the RV. Some people commented that the connectors are difficult to separate, but there is an inexpensive tool you can buy at checkout to make this easy. The instructions say to hook up the solar panels last or cover them so they don't produce a charge until after they are connected to the controller. I cut cardboard covers from the shipping box and taped them to the panels. This allowed me to lay out everything before the final attachment.
