What is an In-Home Assessment?



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.


Unlike competitive units that run at a constant speed, patented G-Flex technology allows the Generac EcoGen to run at lower speeds when household electrical demand is light. That means significantly quieter operation at normal capacity, less fuel consumption when you need less electricity, and cleaner power than competitive air-cooled home standby.

Innovative Extended Run Capability oil circulation system extends the maintenance intervals by an unprecedented 5 times the industry standard by offering 500 hour maintenance intervals.

Generac generators and engines are engineered and built in the USA*.
*Assembled in the USA using domestic and foreign parts

Generac's G-Force Engine is a purpose-built, pressure-lubricated engine capable of handling the rigors of generator use, resulting in power that’s more reliable and requires less routine maintenance than any competitive engine. Learn more about the G‑Force Engine »

3 Year / 2,000 Hour Limited Warranty for automatic standby generators.

Quiet-Test™ Self-Test Mode runs at a lower RPM for a five or twelve minute test, making generators significantly quieter than other brands while consuming less fuel.

24/7/365 Customer Support Team standing by all day, every day from our headquarters in Wisconsin to answer any questions you might have.

Our RhinoCoat™ powder-coated finish helps make corrosion-resistant aluminum perfect for all weather conditions.

Generac’s Evolution™ Controller features a multilingual LCD display that allows users to monitor battery status and track maintenance intervals to ensure your generator is always in top operating condition.

Rated 5 out of 5 by from Off-Grid Replacement As this was a replacement for a much larger (in physical size) generator, it went in very easy. It is small compared to the original, easy of the eyes, and much quieter. I am hoping for good performance with little to no issues. It is nice to have electric at night again.

Rated 5 out of 5 by from Has worked Great for 3 Years! We are off grid with a 15 KW solar power system. I purchased this 15 KW echogen 3 years ago. it now has almost 1000 hours on it and is still running strong at a 6200 foot elevation. I am now looking at a second as a backup. Great product.

Rated 4 out of 5 by from Nice Ecogen Very happy with the new ecogen, but it was only installed yesterday so who knows how it will actually perform. Sound spec was spot on at 63dB from 20'. Documentation is inconsistent. Advertisement says ecogen has weekly test run cycle, but tech support says this model does not. Need to clean that up for a 5 star rating.

Rated 5 out of 5 by from Is a must for the country homeowner. Install and except for maintenance you can forget it's there. Backs up the house 100%. Never without power winter, spring, summer or fall. Can't think of anything more valuable to us as we have moved from suburb living to off the grid. The installers were second to none and did an outstanding job both with install and explanation. Recommend to anyone!!

Rated 4 out of 5 by from well made unit Received the unit and it was just installed. As I'm off grid it will be nice in the winter and stormy days. I don't know how it will perform yet as this time of year we have plenty of sun. It seems to be a well made unit and has many desirable features. Will post another review this winter when it has a chance to perform.

Rated 4 out of 5 by from well made unit I live off grid and just got my Ecogen. It's too soon to know how well it works as it will not get much use until winter when we have sketchy sun. It seems to be a well made unit and has many features that make it desirable. I will send a review in the near future when it gets some use behind it.

Rated 5 out of 5 by from Outstanding design and operation. Just purchased and installed May 15th. My run time each day is about 5 to 7 hours. My main source of power as we live off the grid. The Unit was designed just for my purpose and specific needs, it's great to date. Looncall43

Rated 4 out of 5 by from Reliable, Quite This generator charges our off-grid solar batteries. We are not conservative so it runs every day and does it very reliably. Easy to change oil and most maintenance parts. Wish there were more specific instructions for the on generator control panel.
