Power System Components

Stand alone power system chart for QueenslandBasically, a stand-alone power system comprises:

Method of producing power – i.e. through the use of photovoltaic solar panels, wind generators, water turbines and petrol/diesel generators (and battery charger) or any combination of the above. The ‘hybrid’ system uses a combination of two or more methods of power production.

Deep cycle batteries – for storage of the power generated

Controller/regulator – to regulate the flow of power to the batteries and protect against over charging

Inverter – to convert battery DC voltage to 240 volt AC for use of normal household appliances.

Appropriate wiring – for low voltage, if required, together with adequate fusing, earthing, etc.. It is important that each component is matched to suit the other equipment in the system and a household’s power needs.
