3.3/5
For homeowners who want a quiet, fuel-injected 240V Honda for backup power and will pay a large premium for it. Cheaper dual-fuel inverters offer more watts for the money.

Pros
- Runs 120V and 240V loads, so it can feed a home transfer switch
- Starts from a button or the phone app, no pull cord needed
- Quiet for its size, and it shuts itself off if carbon monoxide builds up nearby
- Runs overnight on a tank at light load
Cons
- Costs several times as much per watt as big inverters from other brands
- About 260 pounds, so it stays on its wheels
- Gasoline only, with no propane option

At its clearance price, a quiet 240V home-backup inverter for far less than the Honda EU7000iS. Yamaha has stopped making generators, so check the retailer’s final-sale terms first.
