Features and Benefits

Quiet-Test™

Generac's exclusive Quiet-Test feature reduces sound levels by lowering engine speed during the generator's weekly self-test. The sound of a QT Series generator during exercise is comparable to a car at idle and meets all known noise regulations.

Sound Attenuated Enclosures

Generac QT Series automatic standby generators feature weather resistant, rodent proof and sound attenuated enclosures as standard equipment.

Aluminum Enclosure

Selected QT Series models feature a corrosion-resistant aluminum enclosure to better withstand the elements. This option is especially important in coastal areas where harsh salt air is especially corrosive.

Natural Gas / LP Vapor Operation

QT Series generators operate on natural gas or LP vapor, providing virtually unlimited run time during extended utility power failures. In addition, gaseous fuels produce far fewer exhaust emissions than diesel, eliminate the need for expensive double-walled fuel tanks and make it easier to get the required permits in most areas.

Easy Installation

Generac's QT Series generators offer the fastest and easiest installation available. All connections within the generator and transfer switches are easily accessible and clearly marked. The generators' light weight allows roof mounting and makes them easy to place without large cranes or specialized equipment. For applications requiring indoor installation, QTA models are available as open gensets.

Automatic Exerciser

An automatic weekly self test of your system ensures that your generator is in peak operating condition at all times.

Fully Automatic Operation

Generac standby generators continually monitor utility power. When the utility fails, the generator starts and signals the automatic transfer switch to lock out the utility and allow electricity from the generator to power the home. When utility power returns, the automatic transfer switch will lock out power from the generator and restore utility power. The generator will shut itself off and wait for the next power outage. Because it's automatic, you never have to worry about a power outage, even when you're away from home.

Proven High Volume Engines

Generac commercial generators use high volume engines that have been well-proven in the demanding trucking industry. These mass produced engines help us keep our prices low and can be easily serviced using readily available, cost-effective parts.

Remote Communications

QT Series models with the H-100 controller and all QTA models are capable of remote system management via computer with the addition of an optional modem and our GenLink software

Remote Annunciator

An optional remote annunciator is available for all QTA models for remote monitoring and seamless integration with existing facilities management systems.

Cold Weather Operation

QTA models come standard with a coolant heater and an optional insolated battery blanket is available for all models.

Battery Charger

A built-in 2 Amp battery charger (10 Amp in QTA models) ensures that the battery remains at an optimum performance level.

Isochronous Electronic Governor

Constant and instantaneous speed control provides faster response time to block loads and a more consistent output frequency. QT Series models with the H-100 controller and all QTA models feature an isochronous governor.

Closed Recovery Cooling System

The closed, pressurized system virtually eliminates the introduction of air into the cooling system. Rust and fluid acidity are minimized, resulting in longer engine life.

Vibration Isolation

Standard vibration isolators virtually eliminate the transmission of vibration from the generator to the mounting surface.

Automatic Warnings and Alarms

Generator functions are constantly monitored through a protective system that features solid state circuitry for reliability and long life. QT Series generators with the H-100 controller provide all NFPA 110 required warnings and alarms for a variety of safety and operational concerns.

Automatic Safety Shutdowns

Automatic safety shutdowns protect the engine and generator in the event of low oil pressure, high coolant temperature, overspeed and/or overcrank.

Solid State Sensing and Starting Control

This feature provides the ultimate in engine protection. The magnetic pickup senses overspeed, automatically shuts down the engine, disconnects the starter motor and prevents re-engagement until the problem has been addressed. The system also provides cyclic cranking for improved starting reliability and cranking termination for starter motor protection.

Brushless Excitor

QTA models utilize a brushless excitor for improved motor starting capability and a cleaner wave form.

Advanced Wire Harness Design with Waterproof Connectors

Our Generac-designed wire harness assures reliable, repeatable interconnection between circuit components. The use of sealed connectors and flexible boots protect against moisture, dust and environmental damage.

Generac Manufactured Alternators

Our revolving field alternators are fully insulated and self ventilating. They feature higher temperature Class H insulation but are designed to operate at lower, Class F temperature levels for longer life.

Superior Paint

Our New Textured, powder coat paint process provides consistent coverage and better bonding to seams and exposed edges. The result is better corrosion protection, greater durability and a longer lasting finish.

Maintenance Friendly

QT Series generators feature large, removable doors to provide fast and easy access for servicing and maintenance.

UL-Listed

All Generac standby generators are UL 2200 listed and our transfer switches are UL 1008 listed. UL listing verifies the kilowatt ratings of our generators and is your assurance that Generac standby systems meet the highest safety standards.

EPA and CARB Emission Requirements

The Environmental Protection Agency and the California Air Resources Board establish emissions requirements for generators up to 25kW. All Generac generators comply with EPA and CARB requirements.

Made in USA

Generac generators are made in the United States by Generac Power Systems Inc. We design and build all of our own major components in one of our four manufacturing facilities in Wisconsin and Iowa. This unprecedented degree of control ensures that Generac products are built to the highest standards for quality, reliability and durability.
