DC and AC Coupling

In an AC coupled system we see power being immediately converted to AC from the direct current (DC), PV source by a grid-following/grid-tied inverter such as a string or micro-inverter. As batteries and energy storage require a DC source to charge, that AC energy will need to be converted back to DC before charging the battery.
