Generac OHVI
®
Engine
THE POWER BEHIND THE #1 HOME STANDBY GENERATOR
Generac’s OHVI engine is specifically for generator use. Why is this important? Generators are often
required to run for hours at a time, day after day. Generac’s OHVI engine utilizes the same type of
pressurized oil lubrication used to give automobile engines long and trouble free lives. This means a
significantly long and the reliability you need when downtime is not an option.
Whether your off-grid location is a choice or a necessity, power is important to you, and you are responsible for producing
the energy you consume. Even when there’s no sun or wind, your batteries continue to deliver electricity, until eventually your
battery bank drains and you are left powerless. Even for off-grid consumers whose needs are fairly simple, this is a dilemma
that can become critical, unless you have a backup power system in place. How long can you go without basics such as heat
and cooling, water, lights, and refrigeration?
Alternative energy system backup options have typically been expensive, inadequately sized solutions adapted from other
applications. Generac Power Systems, the manufacturer of the #1 selling home standby generator, has changed all
that. Knowing an affordable, reliable, low-emission, off-grid backup power solution was needed, Generac engineered the
EcoGen to eliminate virtually all of the issues previously associated with renewable energy backup power options. High
fuel consumption, noise, and short product life have been eliminated by the only off-grid automatic standby generator to
incorporate over 50 years of power generation expertise.
How does it work?
In an off-grid solution, the generator is an important source of backup power when
other resources are insufficient for the demand, improving overall system reliability.
1. Sun (solar cells) and/or wind (turbines) generate DC current.
2. This is fed to the inverter charger and then on to the battery bank.
3. The inverter takes DC power from the battery bank, converts it to AC and
then sends the current to the AC electrical panel.
4. If there is no solar or wind gain and the battery bank level drops below a
preset threshold, the inverter automatically signals the generator to start up.
5. The generator feeds AC power to the inverter, which in turn sends power to
the electric panel and recharges the battery bank to an acceptable level.
Setup options will vary depending on application.
The energy efficient answer to your renewable energy needs.
The outside looks just like our #1 selling
automatic home standby generator.
The inside is unlike any standby generator on the market.
EXTENDED RUN CAPABILITY & LONG LIFE
Exclusive premium oil recovery and circulation system virtually halts oil
degradation. Maintenance intervals are extended by an unprecedented
five times the industry standard, with 500 hours between oil changes.
PROPANE FUELED
Clean burning propane fuel increases efficiency, contributes to longer
engine life, and produces significantly less carbon monoxide than
gasoline fueled engines.
WEATHER PROTECTIVE STEEL ENCLOSURE
The steel enclosure features our RhinoCoat™ finish system. This process
evenly joins paint particles to every part of the metal surface, providing
exceptional protection from the elements on the enclosure and base frame.
NEXUS
TM
DIGITAL CONTROLLER
The state-of-the-art Nexus Digital Controller displays status indicators,
monitors generator performance. The integrated, smart charging
system only charges the battery when necessary. Three position
switch allows for automatic, off and manual functions.
CAPABLE OF 120V OR 240V
Factory wired for a full 6 kW at 120VAC, with the capability to be
reconfigured for a full 6 kW output at 240VAC to accommodate larger
240V inverter systems or two systems paired together.
TWO-WIRE START
Factory equipped to easily connect to the inverter control wires, it
enables the inverter to automatically start and stop the generator in
order to charge the system batteries as necessary.
ULTRA QUIET, LOW RPMS
Only 52 dB(A) under normal load! Vertically mounted, belt-driven
engine drives at 2600 RPMs, resulting in a longer life and drastically
quieter operation than other systems.
WARRANTY
Backed by an unprecedented 3 year/2000 hour limited warranty
when used off-grid in an alternative energy system.
• Built specifically for this application, it is the first automatic
standby generator to be warranted for off-grid use when used in
an alternative energy system.
• Engineered to easily integrate into the existing inverter and
battery storage system.
• Runs on a more environmentally friendly, energy-efficient
alternative – propane gas – that is already stored and available at
many off-grid locations.
• Features Generac’s own V-Twin OHVI
®
industrial engine,
developed specifically for generator use. The low speed makes
it the quietest in the industry, with noise and vibration levels
drastically less than comparable solutions.
• Simplified maintenance with unprecedented 500 hour
maintenance intervals saves time and money.
• Full 6 kW output at 120V
