Excludes portable and inverter generators (see portable-generators), portable power stations, and battery backup systems. Price is typical US MSRP for the generator unit in USD; note whether an automatic transfer switch is bundled. ratedOutputLpKw is the manufacturer rated continuous output running on liquid propane, in kilowatts. ratedOutputNgKw is the rated continuous output running on natural gas, in kilowatts. fuelType is an enum: 'dual-fuel' (accepts both natural gas and liquid propane), 'natural-gas', or 'propane'. coolingType is an enum: 'air-cooled' or 'liquid-cooled'. transferSwitchAmps is the current rating in amps of the automatic transfer switch shipped with the unit; null if no switch is included in the base package. engineDisplacementCc is engine displacement in cubic centimeters. thdPercent is total harmonic distortion at rated load in percent (lower is cleaner power). noiseLevelDbA is the manufacturer-published operating sound level in A-weighted decibels, measured at 23 ft (7 m) at normal/exercise load unless otherwise noted. phase is an enum: 'single-phase' or 'three-phase'. enclosureMaterial is an enum describing the housing: 'aluminum', 'steel', or 'composite'. warrantyYears is the limited warranty length in years. weightLbs is unit weight in pounds.
