Fancy Features but more noise

New unit is much noisier(subjectively) than the old Generac it replaced. It is not just wifi, but cellular connection to maintenance dealer. slick.

Newly installed and on-line once.

Installed in early June 2026 and have been on-line once for less than 2 hours during power outage. I don't know the reliability or life of the unit.

I'm happy that I installed this generator. Being gone much of the time it gives me peace of mind to know if the power goes out I don't have to worry.

Nice but needs more network connectivity.

Great product. Lacking with network function. No 5ghz WiFi and Ethernet is not provided by default which is a money grab.

It was the size needed to run my entire house; it was only used one time for about one hour I was happy I had it.

Our builder installed the generator in April. We thought we had a 7 year warranty but were unable to register it. Very frustrating
