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

5,500W running (7,000W surge) covers a well pump, central AC, and most of a must-run list through a proper transfer switch, at 52 dBA — quieter than almost anything else in this catalog anywhere near this output, let alone the open-frame units running 61-74 dBA at similar wattage. The Honda premium is real here: this costs roughly double a Champion or Westinghouse of similar output. 5.1 gallons and up to 16 hours at 1/4 load means it can run through a full night without a refuel.
