What does the battery do in a solar generator?
At the risk of being overly simplistic, the role of the battery is to store power so that it is available when you need to use it. Solar is an intermittent energy generation source and so it may not be generating electricity right at the moment you need to use electricity. Even if it is generating solar power it may not be generating enough to power the electrical devices that you want to use.
