ReaLoad Technical Verdict & Engineering Dossier

Motor Surge & HVAC Starting

DuroMax XP11000iHT delivers 11,000W surge, sufficient for a 3.5-Ton central A/C with soft-starter. Inverters under 7,500W surge will trip breaker overcurrent protection on direct compressor starts.

72-Hour Fuel Logistics

At 50% load over 72 hours, continuous gasoline generators consume ~56 gallons (11x 5-gallon cans). Direct utility Natural Gas hookup eliminates fuel storage degradation, winter freezing, and gas station queues.

NEC 250.20 Neutral Bonding

Bonded neutral generators require terminal bridge disconnection before connecting to home service panels to prevent double-ground GFCI trips.

ReaLoad Technical Verdict Dossier

Motor Inrush Starting Surge

The DuroMax XP11000iHT delivers 11000W peak surge compared to 8200W on the Westinghouse iGen8200TFc. Starting a 3.5-ton central air conditioner requires an electronic soft-starter to reduce compressor inrush below breaker trip thresholds.

72-Hour Outage Fuel Logistics

At 50% electrical load over a 72-hour power outage, XP11000iHT consumes about 63 gallons while iGen8200TFc burns 42 gallons. Homeowners need 13 sealed 5-gallon gasoline cans or utility natural gas.

Home Panel Interlock Safety

DuroMax XP11000iHT features a bonded neutral, requiring ground jumper removal before connecting to home breaker panels. Follow NEC 250.20 safety grounding rules.
