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.

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.

Beware of additional annual costs

Be careful about the add on costs for maintenance and other cost items not disclosed at purchase time. Could be over $600 annually .

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.

Insurance policy for the future

I purchased this generator in July and the installation was completed in August. The installation was very professional. I would recommend One Way Electric in Phoenix for the installation.

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.

Fast and efficient.

I finished installing my generator a mouth ago. I have my first outage during a storm. The generator performed perfectly. I am very happy I installed this generator system.

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.
