This is a very simple charge controller, it has one LED that will either tell you it's charging or one that will tell you that it's charged. and it comes back a fourth time when the battery is fully charged. The wire provided is smaller than the wire coming from the back of the solar panel. unfortunately I don't know the sizes. The cables speak for themselves, red + black - and very short. NO DIRECTIONS but it's easy enough and if you need these call an electrician maybe even check youtube. wastedmade in China, you get what you pay for, I bought this because it was bought by other buyers who also bought the solar panel I bought. Now I know it's better not to listen to her. try to find something with a digital display. It does the job it was designed for, it can be installed in a lightweight case and all of its indicators work. Both help save energy.
