What Customers Are Saying

Customers overwhelmingly praise the generator for reliable automatic operation, seamless power transfer within seconds, and handling high-demand appliances during outages. Many report life-changing experiences during actual power failures, describing it as a "Godsend" that keeps homes warm and routines uninterrupted. The app notifications and remote monitoring provide significant peace of mind. However, some experience WiFi connectivity issues with the mobile app, and several encountered installation delays or service inconsistencies. Despite these drawbacks, most customers consider it an essential safety investment they wish they'd purchased sooner.

Don't buy this unreliable generator

Would Not Recommend

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.

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.

The delivery men were very helpful and friendly. They put the generator where I indicated to minimize the installers efforts during set-up.

Reliable Power

Would Recommend

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.

Would Recommend

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.

First off the unit was undamaged but the packaging was torn totally apart. The Lowes Assistant asked that I come in look at it before they bring it out. Wow the packaging was trashed. We looked the unit over and saw no apparent damage. I am hoping that when the installer comes to hock it up that everything is there. VERY VERY DIAPOINTED, gives me cause to question where I order next time.
