What can it actually run?
Checked with the same math as our calculator: total running watts, plus the single largest motor surge on top. “Tight” means it technically fits but the load sits above 80% of rated output — fine briefly, not where you want to live.

The installer's take
Wired into an interlock or 30A transfer switch, 7.5 kW carries a fridge, freezer, furnace fan, sump pump, lights, and a window AC with room to spare — for most houses that's an outage you barely notice. Dual fuel means a pair of 20 lb propane bottles can carry you through when the gas stations are down, which is the exact scenario after a hurricane.
Pros
- Real 240V output for transfer-switch installs
- Dual fuel with honest published propane ratings
- Electric start; battery included
Cons
- 202 lb — it moves on its wheels or not at all
- 74 dBA; place it away from bedrooms (and your neighbor's)
