Ratings & Reviews for Generac Next Generation 22000 -Watt Dual Fuel (Liquid Propane/Natural Gas) Home Standby Generator

Never without power

It works great. We are never without power and my wife could always charge her car.

Dependable

Only had it a month and it hasn't been needed, but the weekly exercise runs like clock work and so does the app.

Doesn't run! Doesn't work

15 plus thousand dollars waste of money. Our contractor called the generac service tech at our home 04/17. Unable to reach the generac service tech after the contractor spent most of the day at our home trying to get the generac generator to run.

Nice well installed unit

I purchased less than a month ago and so far very good

Outstanding reliability

My unit is 2 years old and has functioned during outages and twice a month exercising. It is reliable and provides a safety net for me during any kind of outage. The automatic transfer and start up/shut down make operation safe and reliable.

Peace of Mine

This is what we needed for complete peace of mind. Starts automatically (we don’t have to be home), notifies us of status, and let’s deal know if there are any issues so they can plan to service the unit (we don’t need to figure it out and call them). Keeps our life simple and worry free.

Great features.

I bought this generator a month ago and I'm so glad that I did.

so far so good

have had it for a month and no complaints. hasn't kicked in yet since we haven't lost power. so will tell then. yes it's got some noise to it but you can still sit on the deck and talk if it actually has to run.

Comforting to know we are prepared!

I had my unit was installed in April 2025 and it has been used 3 times during power outages so far. Knowing that we are protected and ready for in the event of a power loss is so comforting.

Paperweight at Best

Just purchased the 18kw cellular 15 October 2025 by a Generac dealer. Unfortunately my Propane company couldn't set the tanks until the next morning. The Generac dealer hooked up a 20lb tank to run me through the functionality of the generator. After the Propane company hooked up the tanks to the supply line to the generator, I performed a power outage to ensure there were no issues. The unit lost wifi connectivity. I attempted to reset, but it wouldn't connect. I contacted the dealer/install...

Great reliable generator

I live in the country and all of my neighbors have Generac generators. The only downside would be that a battery was needed to get it up and running. Not a big deal but it would have been nice to have it on hand when setting up the generator. Had to run into town 20 miles one way to purchase one.

Needed during outage

Great product and needed during power outage. Don't be caught without it.

with a Standby Generator you don't worry

I no longer have to worry about hocking up a gas generator when the lights go out

Consider a different product.

I bought this generator 3 years ago. It has run less than 20 hours and already had two components fail. Now my warranty is running out and I am dreading what it will cost to maintain it. My advise is run, don't walk away from this product!
