Generac generators are designed for many applications where power is needed. Generac generators are manufactured to commercial specifications using the latest manufacturing technologies. All models are built with the quality and reliability you would expect from a leading generator manufacturer.

The Generac brushless alternator used on this model is manufactured to exacting specifications using the latest mass production methods. Generac generators use technology to control the voltage with a voltage variation less than 3% throughout the entire power range. That means you can use this generator with computers and sensitive electronics, safely, with no sacrifice in performance.

Open dimensions are 220.9" Long X 90.4" Wide X 103.8" High. Open weight is 25514 lbs. Open quietness is 80 db at 7 meters.

Trailers: Many industrial generators may be mounted on trailers. If trailers are available as a option they will be shown in the Trailer Option Window. Rental type generators equipped with single and three phase power are generally supplied with trailers as standard equipment.

Enclosures: Weather and sound proof enclosures (if available), are built using steel panels and locking doors on a modular structural base frame. Sound enclosures include a rock-wool layer of insulation, which complies with the prevailing regulations and accomplishes the sound attenuating elements. Most enclosures include hot ambient air extraction fan. Select an enclosure from the Product Options windows, if available. For additional enclosure information click on Enclosure Details in the Additional Information area below.

Fuel Tanks: Single walled (non UL) and double walled (UL) tanks are available for this model as shown in Product Options. When base tanks are added, the day tank (if installed) is removed. Tank prices include installation, fuel level gage and fuel line piping, to make a complete operable unit. You may check the running time on that tank size, by viewing the tank in the opened Specification Window or by typing in the gallons or your external tank in the box provided and clicking the arrow. Local codes on fuel tanks vary, check with your local building department and state air quality department to determine any fuel tank requirements for your area. Select the tank you need from the Product Options windows, if available. Select a tank and click "Details" for to see dimensions and other information about that tank. If you have special requirements call your GeneratorJoe sales representative.

Transfer Switches: The automatic transfer switch monitors utility and generator power. When utility power fails or is unsatisfactory, the transfer switch control starts the generator set, checks the generator speed and voltage output and transfers the load to the generator set. When utility power is restored the transfer switch automatically transfers back to utility power. The generator is allowed to cool down for a short period and then shuts down. The system instantly resets itself and is ready for the next power interruption. No action is required by the user.

You must select a transfer switch that is the same size in amps (or larger) then your building service or sub-panel. The transfer switch must also be the same size in amps (or larger) than the maximum output of the generator you select. Example: If you have a 12 kW generator operating at 120 VAC single phase, (100 Amps) and a 200 amp building service you need a 200 Amp transfer switch or you must install a 100 Amp sub-panel. Transfer switches should be installed by a licensed electrician. For more information on transfer switches please see About Transfer Switches.

Select a transfer switch to go with your generator from the drop down option list at the top of this page under Product Options. The transfer switches shown are compatible with this generator.
