AC or DC coupling: Which to use for your next storage project?

Benefits of DC coupling. Efficiency: Each time there is a conversion from AC to DC, or vice versa, there is some amount of energy loss. In DC coupling, the power is only converted once, so there is a marginal efficiency benefit. "DC-coupled systems are great if you''re trying to maximize every watt out of the system," Every said.
