Never Worked

Piece of crap. Never worked when needed. Continues to give default message. Either a lemon or improperly installed.

Works out of the box

Instructions for setup were quite clear, my unit replaced an older model 22 kW unit which contributed to my knowledge base and ease of setup.

Customer care when your product doesn’t work

Definitely not happy with this unit. Every part has been replaced from the initial setup and install

I just got it started up and haven't had to use it yet. Nice to know it is ready to support me when needed.

generator

I purchased this a couple months ago and so far I’m happy, just wish I had better controlled over it through the app.

Security

Had the generator for a year. Have not had to use it. We have not had a power outage. Wish some of the features on the app were free.

New Generac 18Kw Installed in April

I bought it in April and so far it is running good. No loss of power yet, but anxious to see how well it will behave and run.

I sleep well through storms!!

Had the unit put in June of 24 and have had no issues at all. The sense of security it provides is great.
