Could be. I had never considered that. Also, my minimal experience with Generacs has been ok. Sometimes getting UPSs to stop complaining just requires adjusting the UPS to not be so persnickety.Thanks to all for their comments. I've just heard more bad things about Generac than other brands, which might be because there are more of them installed.
Until a few years ago, I had a Class C motor home with an Onan 4kw generator in it. Never needed to do it but since I was able to keep it parked at my house, if I had needed emergency power, that's where it would have come from. Downside was 110 only, no 220. I no longer have the motor home but haven't yet come to a full realization that, "no you DON'T have backup power at home anymore!"
A former radio group with stations here in Omaha had a big Class A they would take out on remotes and such. On their studio building was a connection to hook the motor home's generator to the mission critical stuff in the studios. I thought that was kind of silly until I realized it was rather clever.
On the subject of automatic exercising: all well and good except for one thing. We had some "failed to start" indications last winter. After fixing the problem, the service tech recommended that if the weather was going to be real cold - say, not above 20 and possibly below zero at night - to disable the automatic exerciser feature and just do manually exercising during the day when the temps were warmer. He had seen problems be caused by generator testing in unusually cold weather, when it could have been postponed.
I'm still waiting for some seriously colder forecasts before shutting it off. It tested successfully last night, but 14 days from now might be another story. BTW, the studio generator is labeled Coleman but I suspect someone else manufactures it. Anyone know who the mfg. might be for Coleman generators?
