Power output: running and starting watts

The DuroMax XP5500EH delivers 4,500 W continuously and up to 5,500 W for a few seconds to start motors on gasoline. On propane, the manufacturer rates it at 4,275 running watts (5,225 W starting), 5% less. It handles 14 of the 14 loads on our typical list one at a time; add up the running watts of everything you run together, plus the extra starting watts of the biggest motor.

Fuel tank and runtime

The fuel tank holds 4.0 gallons of gasoline. At half load, it runs about 9 hr on a full tank. That is about 0.44 gallon per hour at half load, or 11 gallons for a full day of running, so plan your fuel storage for a multi-day outage. On propane, a standard 20 lb tank holds about 4.7 gallons of LP; propane does not go stale, which makes it the easiest fuel to stock.

Noise level

The manufacturer does not publish a noise figure for this model. Open-frame generators of this size typically run around 70 to 76 dB(A) at 23 feet; our noise score treats a missing figure as below average.

4

Can you connect it to your house?

Its panel offers 2 × 120 V household outlets (5-20R), L14-30R 30 A 120/240 V twist-lock, 12 V DC outlet. The L14-30R outlet supplies 120/240 V, which is what a manual transfer switch or an interlock kit with a power inlet box connects to, installed by a licensed electrician. Never backfeed the house through a wall outlet.

5

Start type, CO shutoff and warranty

It has electric push-button start, with a recoil cord as backup. The manufacturer does not list a CO shutoff sensor: be strict about placement, 20 feet from the house with the exhaust pointed away. It is listed as EPA compliant; check California availability if you live there. The warranty runs 3 years (residential use).
