ReaLoad Technical Verdict & Engineering Dossier
Motor Surge & HVAC Starting
Predator 13000 Tri-Fuel (71386) delivers 13,000W 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
Genmax has factory floating neutral, safely compliant with 3-pole transfer switches and manual panel interlocks without ground loop faults.
The Genmax GM12000iET delivers 12000W peak surge compared to 13000W on the Predator 13000 Tri-Fuel (71386). 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, GM12000iET consumes about 76 gallons while 13000 Tri-Fuel (71386) burns 66 gallons. Homeowners need 16 sealed 5-gallon gasoline cans or utility natural gas.
Home Panel Interlock Safety
Genmax GM12000iET provides a factory floating neutral ready for standard 3-pole manual transfer switches.
