Just ordered my third of these solar charge controllers. I originally bought two because of the small size and both are working great after two months of use. I have no idea if they are actually waterproof as they come in a little project box that protects them. Remember to connect them to the battery first before connecting them to the solar panel. The first two photos show a solar charger feeding a 12v power regulator (buck converter) to ensure my security camera is constantly on 12v and not what the solar panel is supplying. The other three refer to another solar charger that proves the power started by a remote switch. Will buy more for other solar projects.
