Dual-fuel · XP28000iH
XP28000iH: 22,000 running watts. Two fuel choices.
DuroMax XP28000iH Dual-Fuel Inverter Generator pairs 22,000W of gasoline running output with gasoline and propane operation. Build a high-demand, professionally planned backup configuration, then size your connections around the exact fuel-specific ratings below.

Fuel options
Choose your fuel. Keep the load calculation precise.
The XP28000iH lets you choose gasoline or propane without treating them as identical power sources. Gasoline running output is 22,000W; check the propane running rating in the specifications when calculating a propane-powered load.
The listed starting rating is 28,000. Starting output covers brief startup demand; it is not the amount available continuously. Allow for equipment starting requirements as well as the combined running load.
Match the load. Choose the connection.
Running output and startup demand are different requirements. Add together the loads you plan to use simultaneously, then compare the applicable fuel-specific ratings. Runtime changes with load, fuel and conditions.
Keep this fuel-powered generator outdoors, away from doors, windows and vents. Connecting it to building wiring requires appropriate transfer equipment and qualified installation. A carbon monoxide sensor does not make indoor use safe.
Check your connections before you connect.

Before you choose.
Will it run my equipment?
Compare the combined running and startup requirements, voltage and connectors with this exact configuration. Do not treat peak output as continuous output.
Does this replace a professionally installed system?
Keep this fuel-powered generator outdoors, away from doors, windows and vents. Connecting it to building wiring requires appropriate transfer equipment and qualified installation. A carbon monoxide sensor does not make indoor use safe.
Which configuration am I ordering?
XP28000iH. Standalone generator configuration. Match the model and listed package contents before ordering.
