Reliable Protection

Purchasing this generator was similar to putting up a magical ward against power failures. Where the original motivation was a frequent number of outages, we've not had any single outage since installation. In it's standby configuration it's met our expectations.

Generator Upgrade

This is our second Generac generator because, after 19 years with our first one, we wanted to upgrade to one with more current features/functions. Our first one was purchased in Sept. 2007. It gave us optimal, quality, and dependable service. It is still working today, in another household, with a family whom we gave it to. We look forward to and are confident that we will have the same level of quality service with our recent new upgraded generator!

Hurricane Prepared

4 years after Hurricane Ian it was time to replace a portable 5kw generator with a whole home generator. We will now be able to have the entire house on standby power should another major outage occur. Being familiar with the Generac company based in Wisconsin, this was the only generator considered.

Reliable Power

Just completed year two annual maintenance. Generator has activated reliably 5 times over the past two years and powered my home without any issues. Propane usage seems very efficient.

Good generator for the entire house.

Have had this generator for a year. Had to have a faulty emergency switch replaced (under warranty). I've put about 11 hours on it. It's able to power everything in my 2500 sq/ft house (A/C, Heat, oven, dryer) all appliances with no issues.

Generator is great! Mobile Link app….not so much.

The unit was installed on a Friday and we lost commercial power for 23 minutes the following Monday. The unit operated flawlessly! The only drawback I’ve found is the inability to see realtime unit loading and voltage in the Mobile Link app.

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.

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.

Something is Wrong with it

I bought this a month ago and it’s still not working properly. It runs for 15 seconds and then shuts off. After five cycles of this it stops altogether. They are still trying to figure out the issue. I am happy to review again once it works properly.

Don't buy this unreliable generator

I bought this NextGen 28kW to replace a rusty but reliable 20 year old 35 kW Generac. Our NextGen failed immediately at our first power outage 3 weeks after installation and is still nonfunctional after 3 service trips and more than 4 hours labor over the last week.
