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.

Great Whole Home Generator for my house.

I purchased this one month ago and could not be happier. The installation went great. Generator runs like a clock every week for it's week test.

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.

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.

Poor Product

Generator was installed and does not work. Installer is doing their part to troubleshoot. Extremely disappointed with the product, not the installer.

We had it installed for one simple reason. My wife is on oxygen and we can not have a power failure endanger her life and wellbeing.

Seamless Power

We purchased a NextGen 24kW w/transfer switch about a month ago and have already had utility power interruptions twice. The system operated seamlessly. We are very happy with the purchase, installation, and its operation.
