Quiet, capable whole-house generator

After only two uses, this generator proved notably quiet for its size. All outlets and eco-mode were tested. A large 120V grinder ran without pushing it off eco-mode. Connected to a house, it handled loads without strain, including a 4-ton AC with a soft start module, which only briefly loaded it before it idled down and cruised. It is expected to more than meet household needs and comes highly recommended.

Pros
  • + very quiet for its size
  • + handles large loads without strain
  • + runs a 120V grinder without leaving eco-mode
  • + handles a 4-ton AC with soft start
  • + idles down and cruises under load

Tri-fuel inverter generator with strong build and handy features

This tri-fuel inverter generator runs on natural gas, is quieter and more fuel efficient, and can power a whole house with watts to spare. It arrives in sturdy packaging with accessories including a cover, NG hose, propane hose, bonding plug, and magnetic dipstick. Build quality feels high, and an oil filter adds peace of mind. A leave-in battery charger keeps it ready for outages. Cold starts on natural gas sometimes need a second press of the electric start to bleed the line, then it runs well. The wattage readout and front-panel LED light are useful. It connects via a 50 amp inlet and interlock kit with no issues, and the floating neutral works for home backup without modification.

Pros
  • + runs on natural gas
  • + quieter and more fuel efficient inverter design
  • + can power a whole house with watts to spare

  • + works with 50 amp inlet and interlock kit

Voltage Fluctuation and Poor Support Mar This Generator

This 9000-watt inverter generator, intended for 240V and 50A output, arrived with a display that constantly switched between 120V and 240V. A replacement display did not fix the issue. Support was difficult to reach and eventually suggested taking the unit to a repair facility 40 minutes away. A repair shop confirmed the voltage fluctuation, but support stopped responding. Instructions for floating neutral mode did not match the unit's wiring, and support later said no instructions were available, requiring a paid electrician or voiding the warranty. The return window has passed, leaving the unit unusable for its intended purpose.

Cons
  • − Voltage fluctuates between 120V and 240V
  • − Replacement display did not fix the issue
  • − Support is difficult to reach and unhelpful
  • − Repair facility is far away
  • − Neutral mode instructions do not match unit wiring
  • − No instructions available for floating neutral mode
  • − Must pay for electrician or void warranty
  • − Return window passed
