PRODUCT FEATURE: Qnergy’s PowerGen N+ Solutions – Scalable Power and Reliability


Qnergy’s proven 5.65kW PowerGen Stirling engine can be paralleled to scale up power and reliability in critical off-grid power applications. Whether it be standby power redundancy or higher power applications, the ultra-reliable, clean burning Stirling engines can be dispatched to meet your custom power needs. No need to struggle with oversized high maintenance gensets, load banks and diesel fuel. The Free Piston Stirling engine’s lean external combustion process can run on various grades of natural gas and tanked propane.


  • Scalable for 5, 10 and 15kW power levels
  • Seamless backup battery integration
  • Increased system reliability
  • Fuel consumption optimization (Propane or Natural Gas)
  • Can readily be hybridized with renewable energy sources (i.e. PV and wind)
  • Reduced maintenance and cost of ownership
  • Dispatchable generation
  • IOT connectivity

Stirling Advantage vs Traditional Engines

  • Maintenance free 80,000h engine life (no oil changes, no field rebuilds)
  • Efficient, low-emission combustion (100x lower than EPA CO and NOx limits)
  • Wide operating temperature range (-40˚C to 40˚C)
  • Load-following engine (no load banks or wet-stacking issues)
  • SmartView web-based monitoring system
