QT Series generators are a reliable, cost-effective
backup power solution for commercial establishments
and small businesses. There are more than ten models
to choose from, ranging in output from 20 to 150 kilowatts,
plus an array of automatic transfer switches. These
compact, powerful gensets are ideal for a broad range
of enterprises, including restaurants, convenience stores,
supermarkets, banks, fitness centers, hotels, and retail
All QT models are available with two fuel choices —
natural gas or liquid propane (LP) vapor. Kilowatt ratings
are based on LP fuel (power output may be slightly less
with natural gas)
Standby power is indispensable for many kinds of operations.
Lengthy or recurring power outages result in financial
loss, inconvenience or worse. Often, the investment
in a standby generator set is recouped at the first
Generac's broad product line offers a full range of
models for all kinds of applications, in both diesel
and gaseous fuel options.

Power generation equipment is built to exacting requirements.
By its very nature, it must be safe, reliable and capable
of routinely handling heavy electrical loads upon demand.
That means uncompromising attention to close tolerances
and exacting details, requiring manufacturing expertise
and quality assurance at every step of the process.
The heart of every Generac genset is its engine and
alternator. For our prime movers, we select top engine
designs from around the world that are ideally suited
to electrical power generation and modify them to Generac
specifications. Starting with each long block engine,
we add Generac-designed fuel delivery, cooling, and
exhaust systems. Depending upon size, 98% of our alternators
feature Generac manufactured rotors and stators. As
an extra measure of safety and confidence, most Generac
products are UL Listed by Underwriters Laboratories.

well-proven control system ensures reliability and durability
Permanent magnet excitation (optional at 125 kW and
below) — Provides better response time and better
performance for non-linear (UPS) loads, and is standard

Research, Development & Testing
Our numerous research and development programs are
all aimed at bringing improved products to market. In
order to stay on top, we focus on and apply new technologies
to increase power, efficiency and reliability.
To ensure that our equipment lives up to the Generac
reputation for durability, we subject our engines, alternators,
controls, and transfer switches to punishing test routines.
Only after we’re certain they’re up to the
task do they become a part of our product line, where
long life is a hallmark of our commitment to lasting
New systems are subjected to rigorous product performance
tests, as well as extensive alpha and beta site testing.
Our extensive test agendas allow you to choose a Generac
power system with the confidence that every system will
provide you with the power you need, for years to come.
