Patented G-Flex
™
Technology
Exceptional Fuel Efficiency. Uncommonly Quiet Operation. Cleanest Power.
Traditional home standby generators have to run at a constant speed to produce usable electricity. Patented G-Flex
technology allows the Generac EcoGen home standby generator to vary its speed based upon electrical demand. It will
run slower—and quieter—when you use less electricity. And during its weekly exercise, you’ll hear only about as much
sound as if you were riding in a luxury car. The Generac EcoGen also consumes less fuel when electricity demand is light,
saving you money. And G-Flex technology delivers electricity with less than 2.0% total harmonic distortion (THD)—lower
than IEEE standards for utility power—to properly power modern electronics and sensitive appliances.
Unprecedented Service Intervals
The Generac EcoGen’s exclusive premium
oil recovery and circulation system virtually
halts oil degradation, and allows for 500
hours between oil changes—five times the
industry standard.
Two-Wire Start
Factory-equipped to easily connect to the
inverter control wires so that the inverter
can automatically start and stop the
generator in order to charge the system
batteries as necessary.
Limited Warranty
Unlike conventional home standby
generators used in an alternative energy
system, the Generac EcoGen is backed by
a 3-year/2000 hour limited warranty.
Designed Specically
for Off-Grid Use
Automatic Voltage Regulator
(AVR)
The brains behind the G-Flex technology, the
AVR monitors electrical demand and reduces
engine speed accordingly. It also keeps tabs
on alternator output frequency at lower engine
speeds. Then it electronically manipulates
alternator output to achieve 60 Hz electrical
power. In doing so, it produces exceptionally
clean power—less than 2.0% THD.
Evolution
™
Controller
The next generation of intuitive controllers, the
Evolution controller features a multilingual, two-
line LCD text display with color-coded backlit
buttons.
Skewed Stator
Produces a smooth output wave
form for compatibility with sensitive
electronics.
Extended Operation Oil Reservoir
Provides additional oil capacity for extended oil
life with fewer required maintenance intervals.
Resonator
The unique resonator is specifically designed
to improve sound quality and minimize overall
sound levels. The result is a lower tone that,
when combined with the generator’s quieter
operation, is more pleasing to the ear. During its
weekly exercise, the Generac EcoGen is about
as quiet as riding in a luxury automobile.
Specialized Alternator
The rotor has three windings instead of the
normal two. They are electronically controlled by
the AVR to ensure 60 Hz output, even at a lower
speeds.
