What the numbers mean
At 7,600 running watts
on its best fuel, this unit covers a partial-home setup through a 30 A transfer switch or interlock: refrigerator, furnace, a well or sump pump, and lights, with load management for anything bigger.
Runs on gasoline, propane — expect lower output on propane (roughly
10%) and natural gas (roughly 20%) than on gasoline; the spec table shows the
published per-fuel ratings.
Runtime: 11 h at 50% load on the 6.9-gallon tank
— roughly 17.6 h at 25% load (estimated)
.
Estimated fuel cost for 24 h at ~50% load: about $48 on gasoline at
national average prices (assumptions).
House hookup: pairs with a 50 A generator inlet (
14-50 / CS6365) and a transfer switch or interlock
installed by an electrician.
What can the DuroMax XP9000iH Dual Fuel Inverter run during an outage?
With 7,600 running watts on its best fuel, the DuroMax XP9000iH Dual Fuel Inverter covers a partial-home setup through a 30 A transfer switch or interlock: refrigerator, furnace, a well or sump pump, and lights, with load management for anything bigger. Add up your actual loads with a sizing worksheet — the bands here are rough guidance, not a load calculation.
How long does the DuroMax XP9000iH Dual Fuel Inverter run on a tank of gas?
About 11 hours at 50% load on its 6.9-gallon tank, per the manufacturer's rating. At a lighter 25% load, figure roughly 17.6 hours (estimated — fuel burn does not scale linearly with load).
What does the DuroMax XP9000iH Dual Fuel Inverter cost to run for a day?
Roughly $48 for 24 hours of continuous operation at about 50% load on gasoline, at national average fuel prices. The assumptions behind this estimate are documented on the methodology page; your fuel price and load change the figure.
Does the DuroMax XP9000iH Dual Fuel Inverter have a CO safety shutoff?
Yes — the DuroMax XP9000iH Dual Fuel Inverter has a built-in carbon monoxide sensor that shuts the engine down when CO accumulates around the unit. It is a backstop, not a substitute for running the generator outdoors at least 20 feet from the house.
What inlet does the DuroMax XP9000iH Dual Fuel Inverter need to power a house?
A 50 A generator inlet (a 14-50 or CS6365 connection) wired to a transfer switch or interlock kit — an electrician's job that normally requires a permit. Never backfeed through a dryer or wall outlet.
