Off-grid solar systems, also known as stand-alone solar systems supply electricity to properties that are not connected to the public electricity network.

During daytime, electricity is generated by the solar panels (1). The solar PV inverter (2) converts the DC power to AC power and either directly powers your electrical loads (3) or/and charges batteries (5) via an Off-Grid inverter/ battery charger (4). During the evening or on cloudy days when the sun isn’t shining you use the power stored in the batteries “Battery Bank” (5). When the sun comes up the next day, the cycle begins again. The third available power source is a backup generator (6) that can be integrated into the system.

There are two different ways of configuring an Off-Grid 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.
