Storing costs electricity: The issue of conversion losses
No matter how you look at it, storing energy in a battery costs electricity! Usually it is own electricity from the photovoltaic system that is lost through one conversion or another. For a normal AC-coupled system, we have roughly calculated this and come up with an energy efficiency of approx. 70%.
