Why do I need to connect the case to a ground if the negatives from the solar panel, the battery, and the load are all connected? What would the ground connect to on the other end?
Good looking unit with easy setup. App is very easy to use as well, and can see charging status and changes almost instantly. Will buy more for additional outbuilding setups...
