Runs whole house including 4-ton AC without flinching
Ordered the Genmax Gm9000Iet 9000W Portable Tri Fuel Inverter Generator after getting tired of sitting in the dark during Gulf storms. Freight delivery arrived on a liftgate truck right onto my concrete driveway. Hooked it into our manual transfer switch with a 50A cord and ran our central 4-ton AC, two refrigerators, well pump, and all household lights. Electric start fired right up on fuel.

Clean freight delivery and great build quality
Driver called me 24 hours ahead of time to coordinate delivery. Unit was bolted onto a heavy pallet and wrapped securely. Added oil, connected fuel source, and pushed the start button. Purrs like a kitten and the digital meter makes monitoring voltage and hours simple. Couldn't ask for a better machine at this price point.

Fuel versatility and clean power output are a lifesaver
The fuel versatility on this Genmax Gm9000Iet 9000W Portable Tri Fuel Inverter Generator was the main selling point for me. Being able to connect directly to propane or natural gas means no more storing 50 gallons of stale gasoline in the garage. Build quality is solid industrial grade and the frame feels bulletproof.

Remote start key fob works from inside the house
Tested the wireless remote start from about 80 feet away through the back patio door—started immediately. It is surprisingly quiet for an engine of this displacement. Very impressed with the packaging and complete hardware kit included.

Questions & Answers
Need transfer-switch sizing, natural gas BTU flow, or liftgate scheduling confirmed before ordering? Talk directly with our Dallas equipment desk.
What fuels does the GM9000iET run on?
It runs on gasoline (9,000 W starting, 8,000 W running), propane (8,000 W starting, 7,000 W running), and natural gas (7,000 W starting, 6,500 W running).
Can it back up my house?
The 50A 120/240V outlet is the connection normally used with a home transfer switch or interlock kit. Have a licensed electrician size and install that connection.
Is this the same engine as the GM9000iED?
No. GENMAX lists a 349cc engine and a 138 lb weight for the GM9000iET. The GM9000iED is the enclosed 458cc model at about 244 lb.
How does Free Curbside Liftgate Delivery work?
Ships free from our Dallas depot (5800 Industrial Blvd) via insured LTL freight with a 24-hour advance call and hydraulic liftgate lowering to your driveway.
Why is this unit discounted below standard retail?
We acquire unclaimed contractor freight allocations directly into our Dallas warehouse. Every unit is 100% factory-sealed (0.0 hrs) with our serialized 3-Year Warranty.
