Get a quoteFor Off-Grid Solar, the difference between DC- and AC-coupled systems is how the battery bank is charged in the system: DC-coupled systems charge the battery bank with DC power directly from the PV array. AC-coupled systems convert DC power from the PV array to AC power, then convert this AC power back to DC power to charge the batteries.
