discussion on the method of storing excess power in power grid
What happens to excess energy fed into the power grid?
If the excess energy goes beyond the tolerance of the devices, they will overheat and/or burn ( cause damage ). These results will be obtained regardless of what causes the "excess energy" on the grid (lightning, solar installations, wind power, etc.). For the last two questions, if you are charging a 12v battery with a 13v source, the extra 1v ...
