Stand-alone Power System
From Wikipedia, the free encyclopedia
A Stand-alone Power System (SAPS or SPS) is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system. SAPS was previously called Remote Area Power Supply or RAPS), as they are most often used in remote locations.
Typical SAPS include one or more methods of electricity generation, energy storage, and regulation.
Electricity is typically generated by one or more of the following methods:
- Solar panel
- Wind turbine
- Geothermal source.
- Micro combined heat and power.
- Micro hydro.
- Diesel or biofuel generator.
Storage is typically implemented as a battery bank, but other solutions exist including fuel cells. Power drawn directly from the battery will be direct current extra low voltage (DC ELV), and this is used especially for lighting as well as for DC appliances. An inverter is used to generate AC low voltage, which more typical appliances can be used with.
