Runs whole house including 4-ton AC without flinching

Ordered the GENMAX GM7500iAED 7500-Watt Dual-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 propane.

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 a 100-lb propane tank, 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 is a complete lifesaver

The tri-fuel capability was the main selling point for me. Being able to connect directly to our residential natural gas line 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.
