Can it really power a whole house?

With 10,500 running watts on gasoline it can carry a typical home's essentials and many large loads, but central AC plus electric heat and an electric range at once may exceed it. Match your loads to the running wattage, not the peak.

How does propane affect output?

Propane drops output to 12,750 peak and 10,000 running watts. It avoids gasoline storage and carburetor issues, but you get less power per unit of fuel.

Is it safe for electronics?

Yes. It is an inverter generator with total harmonic distortion under 3%, which is clean enough for computers, TVs and medical devices.

How do I connect it to my house?

Use the 50A 14-50R outlet with a transfer switch or a breaker interlock kit installed by an electrician. Never backfeed a dryer outlet or a regular wall plug.

What can the DC output charge?

It can charge 48V/52V battery banks such as a Tesla Powerwall, which helps top up storage during long outages.

Push-button electric start is primary, with a wireless remote and a backup recoil pull start if the battery is low.

It has a 550cc, 4-stroke OHV engine with forced air cooling and a cast iron cylinder sleeve. The windings are 100% copper, and an AGM battery supports starting in cold weather. You can start it with the push-button electric start, the included wireless remote, or the backup recoil pull. It shuts down automatically on low oil or when its CO sensor trips.

The 50 Amp 14-50R outlet works with a transfer switch or interlock kit for home backup. A DC output charges 48V/52V battery banks such as a Tesla Powerwall. The power panel has a digital voltmeter, an hour meter, a battery switch and GFCI-protected outlets. The generator weighs 234 lbs on its wheel kit.
