ReaLoad Technical Verdict & Engineering Dossier

Motor Surge & HVAC Starting

Predator 3500 Inverter delivers 3,500W 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

Predator has factory floating neutral, safely compliant with 3-pole transfer switches and manual panel interlocks without ground loop faults.

ReaLoad Technical Verdict Dossier

Motor Inrush Starting Surge

The Predator 3500 Inverter delivers 3500W peak surge compared to 4375W on the Predator 4375. 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, 3500 Inverter consumes about 30 gallons while 4375 burns 36 gallons. Homeowners need 7 sealed 5-gallon gasoline cans or utility natural gas.

Home Panel Interlock Safety

Predator 3500 Inverter provides a factory floating neutral ready for standard 3-pole manual transfer switches. Follow NEC 250.20 safety grounding rules.
