Portable Diesel Power

With a weight of 247 pounds (empty), the Generac XD5000E may be less “portable” than other jobsite generators, but its heft makes up for itself in features. The diesel-powered Yanmar LW air-cooled direct-injection engine provides significantly longer runtimes—Generac estimates 32 hours at 50% load (compared with eight to 10 hours for gas-powered models). Harmonic distortion runs at less than 6%, for cleaner operation of sensitive loads like smartphone chargers, laptops, and testing equipment. When the unit runs low on oil, it automatically shuts down, and a 120/240V selector switch provides power for any of your jobsite tools. A single-touch electric start means you won’t have to put your coffee cup down to fire it up. Advanced emission technology ensures Tier IV compliance from the EPA so it burns diesel cleanly too. An integral lifting eye allows the unit to be moved by machine, or a wheel kit can be purchased separately. The price tag is a hefty $3,700, but according to Generac’s product manager, Matthew Moose, the longer runtimes and long service life mean more readily available power, so no downtime. It comes with a two-year limited warranty.
