for Off-Grid Use

Generac EcoGen

Generac's EcoGen is the solution for automatic backup power in an alternative energy system, like wind or solar power.

Designed Specifically for Alternative Energy Systems.

The first backup generator warranted for off-grid use

Whether you're off grid by choice or necessity, you're responsible for the production of the energy you consume. Even when there’s no sun or wind, your batteries continue to deliver electricity. Unless you have a backup power system in place, your battery bank will drain. Generac engineered the EcoGen home backup generator as the first automatic backup generator warranted for off-grid use when used in an alternative energy system. It integrates easily into your existing inverter and battery storage system. And it runs on your existing LP fuel supply.

Why Invest in Backup Power in an Alternative Energy System?

Even with wind or solar power, there is a chance your batteries will drain, leaving you without power. EcoGen can recharge your batteries in the interim. See how the features of the EcoGen home backup generator make it ideal for off-grid use in an alternative energy system.

EVOLUTION™ CONTROLLER

The next generation of intuitive controllers, the Evolution controller features a multilingual, two-line LCD text display with color-coded backlit buttons.

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.

Extended Operation Oil Reservoir

Provides additional oil capacity for extended oil life with fewer required maintenance intervals.

SPECIALIZED ALTERNATOR and Skewed Stator

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. The skewed stator produces a smooth output wave form for compatibility with sensitive electronics.

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.

Greener, Efficient, Abundant Fuel

Clean-burning propane fuel increases efficiency, contributes to longer engine life, and produces significantly less carbon monoxide than gasoline-fueled engines. Propane gas can be stored indefinitely and is available at many off-grid locations.

Extended Run

Our exclusive premium oil-recovery and circulation system virtually halts oil degradation, resulting in greatly extended maintenance intervals—an unprecedented five times the industry standard, with 500 hours between oil changes.

Quiet Performance

The EcoGen is  and significantly quieter than a portable generator or a standard Guardian® Series home backup system.
