There are two different ways of configuring a remote area power system; these are known as AC-Coupling and DC-Coupling, each having their unique advantages. The configuration type will have an impact on the life expectancy, efficiency and flexibility of your system.

AC Coupling is a method of inserting Solar into a battery based system via the AC circuit rather than the traditional DC Circuit. To do this, a standard Grid Tie inverter is used to turn the high voltage DC from the Solar Panels into AC Electricity. AC Coupling is highly efficient for “Self Consuming” Solar Power.

DC Coupling is the traditional method of inserting Solar into a battery based system via the DC circuit. To achieve this, a Solar Controller or Maximum Power Point Tracker (MPPT) is wired between the Solar Panels and the battery. DC Coupling is highly efficient for charging batteries.
