Generac EcoGen Series Generators
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.
6kW Generator

Designed specifically to interact with off-grid renewable energy applications, the EcoGen 6 kW is the first generator intended for alternative energy system standby power. It’s engineered to easily integrate into an inverter and battery storage system, providing a cleaner running, low emission solution for recharging battery banks in an off-grid application.
- Extended run capability & long life are gained from our exclusive premium oil recovery and circulation system that virtually halts oil degradation. Maintenance intervals are extended by an unprecedented five times the industry standard with 500 hours between oil changes.
- 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 features our durable powder-coat finish system, providing exceptional protection from the elements on not only the enclosure, but also the base frame.
- Warranty – backed by an unprecedented 3 year/2000 hour limited warranty when used off-grid in an alternative energy system.
- Nexus™ Digital Controller features an LCD display with status indicators, monitors generator performance, and also records any issues for easy troubleshooting. 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.
- Factory equipped with two-wire start 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.

15kW Generator

Whether the off-grid lifestyle is a choice or a necessity, you are responsible for producing the energy you consume – even when there’s no sun or wind. Ensure you never have dead batteries with the Generac EcoGen–the only automatic standby generator designed and warrantied specifically for off-grid use with an alternative energy system.
- Purpose Built For Renewable Energy Applications designed specifically to interact with off-grid renewable energy applications, Generac introduces the first generator intended for alternative energy interaction. It is capable of tying into an inverter and battery storage system to supplement the alternative energy source. This provides the cleanest running, low emission solution to recharging house batteries.
- Extended Run Capability This innovative oil circulation system extends the maintenance intervals by an unprecedented 5 times the industry standard by offering 500 hour maintenance intervals.
- G-Flex™ Variable Speed Technology By utilizing patented variable speed technology, the generator is capable of running at various RPMs depending on the electrical demand, resulting in quieter operation, better fuel economy and produce power at <2.0% total harmonic distortion for quality power.
- OHVI® Engine the Generac OHVI® engine, specifically designed for generator use, provides the reliability to power through the most sever outages. engineered and built in the usa.
- Evolution™ Controller The next generation of intuitive controllers, the evolution controller features a multilingual, two-line lcd text display with color-coded backlit buttons.
- Convenient Installation can be installed only 18” from the home, if located away from doors, windows, and fresh air intakes, unless otherwise directed by local codes.
- Rhinocoat Aluminum Enclosure Our durable Rhinocoat powder-coat finish helps make sturdy aluminum enclosures perfect for all weather conditions. Enclosure is able to withstand 150 mph winds.
- Fuel Options with Tool-less Conversion the Generac Ecogen runs on LP fuel or natural gas, and easily converts during installation without the need for tools.
