Stirling Engines

The Qnergy PowerGen Remote Power Generator combines the high efficiency Free Piston Stirling Engine (FPSE) technology with advanced combustion capabilities to efficiently transform propane, well gas and natural gas into electricity.  The external combustion engine and automatic control system enable the generator to produce steady, dependable power from 1.2kW up to 5.6kW.

How It Works?

Using a highly efficient thermodynamic process, Qnergy's Free Piston Stirling Engine (FPSE) can create electricity from virtually any heat source.  The heat input creates a temperature differential across the engine causing the helium inside the engine to expand and contract, which in turn drives the reciprocating motion of the piston.  The FPSE directly converts the reciprocating motion of the piston into electrical power via the linear alternator inside the engine.
