Here you get what you pay for. This is the bottom section of the solar controller. Suitable for use with one or two panels and one or two batteries. Needless to say, a good controller. When using it for applications that don't require heavy lifting. I actually burned mine, but that was my fault. Tried to smash through a lot of amps. Where it is written it worked fine - 20 amps, I wanted to try more. It did not work. It really works as intended. Setup is very easy. They have solar, battery, electricity. That's easy. You get a controller that tells you all sorts of things. You can leave the settings on Automatic, but if you want to tweak something, you can. This controller is for beginners. He will introduce you to solar energy and show you the potential of what you can have. It's perfect for light workloads and you won't be disappointed if you buy it for this type of use. He will do what you want and he will do well.
