A Remote Area Power Supply (RAPS) is a system that provides electricity in remote locations, without requiring connection to an electricity distribution system. RAPS is now typically called a Stand-alone Power Systems (SAPS or SPS), as the same off-grid systems may exist in less remote locations.

Typical RAPS include one or more methods of electricity generation, energy storage, and regulation.

Electricity is typically generated by one of the following methods:

• Solar panel
• Wind turbine
• Micro combined heat and power
• Micro hydro
• Diesel 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.
