Looks serious and sturdy

I purchased this generator one and a half years ago and we have already had to use it twice for more than 24 hours

satisfied

We have had our generator for two years. No problems and the installer comes back annually to inspect.

Excellent Purchase

I live on a mountain and spend a lot of time traveling. This gives me the peace of mind that I need when I'm traveling.

Great features of this unit are enjoyed

This unit has been in service for over a year and I'm happy with everything about it. Especially the service company.

Peace of mind

I had this unit installed one year ago. The unit switched on twice for 2 minutes each time. I am very satisfied to have the unit available, especially during hurricane season.

Minor problem fixed by firmware update

We have only had it for a little over a month and so far, so good. We did have 2 "overcrank" reports that required resetting, but after installing the firmware, we no longer have that issue.
