Abstract

An electrical power supply system (22) comprising an electrical energy storage device (10), typically in the form of a battery bank, and an inverter (14) for supplying AC electrical power, derived from the electrical energy storage device, to a load (12). The system further includes an electricity generator (16) for charging the elecrical energy storage device and for supplying the load when the storage device is being charged. The electricity generator is switched on when the electrical energy stored by the electrical energy storage device drops below a predetermined first level, and is switched off again when the electrical energy stored by the electrical energy storage device reaches a predetermined second level above the first level.
