Inverters

Most household appliances use alternating current (AC) electricity, which is what comes out of the power point of a mains-grid connected house.

However, the batteries used in stand alone system, supply (DC) electricity. To make conventional appliances run in a stand alone system, this DC electricity must be converted to AC. This conversion is done by an inverter. The inverter is connected to the battery bank, and provides mains-type AC electricity to the system. The inverter needs to be sized to suit the system's electrical requirements.
