9.1 HOUSEHOLD POWER SYSTEMS
Remote area power supply systems in non-grid areas may take on a range of
configurations with a mix of possible electrical energy generating sources, plus
inverters and batteries. Present generating options include:
x photovoltaic modules
x wind turbines
x small hydroelectric generators
x diesel or petrol generators
x hybrid systems comprising two or more of the above.
In Australia, these remote area power supply systems are generically called RAPS
systems and are typically used for loads larger than simple PV-battery systems. They
were developed originally for rural homesteads, stations and holiday homes, but are
now being used for small community power supplies, in Aboriginal settlements and
on islands.
RAPS systems are installed for a range of reasons, including:
x expensive grid connection (Krauter, 2004)
x grid overload, resulting in unreliable supply
x desire to use renewable energy
