DC Coupled Solar Batteries
A DC system connects directly to your Solar Panels before your generation meter. In a DC-coupled system, Direct Current flows from your solar panels to a charge controller that feeds into your battery system. This means that any electricity generated by your solar panels, will be only inverted once from DC to AC. Either at the point where the current flows from your battery to your home, or from your battery to the National Grid.
