The ReadySource™ standard feature is a four stroke class. Most diesel engines generally use the four-stroke cycle for smoother, quieter operation.

Gensets produce either single or three phase power. Most homeowners require single phase. Industrial or commercial function usually requires three phase power. Diesel engine generators are recommended due to their longevity and lower operating costs. Modern diesel engines are quiet and generally require much less maintenance than comparably sized gas (natural gas or propane) units.
