Generac QT130 Backup Generator - Power Failure Test

Utility power failure test and in-phase transfer of a Generac QT130 backup generator (model # QT13068GNSN). A soft start is a staggered start that prevents the engine from going from a dead start to full RPM in just a few seconds. Instead the engine stops at several Hz intervals, which is much easier on the engine. This full speed test at ~3000 RPM at 60 Hz produces engine noise above 100 decibels at 6 feet. Hearing protection is recommended if you are to be around the generator running at this level for long periods of time.

QT.... and that's their quiet enclosure....what a POS.

75dB at 7 meters? That's a sack of crap but they publish it.

3000 RPM ? How can Cat, Onan and others do it at 1800 rpm?

No wonder the "trade" calls them Generjunk.

@murymann You would not believe the problems we've had with this generator. Well actually you probably would.

Looks like a semi - tractor trailer enclosed in an aluminum housing and trapped for life!

I don't know what you guys are complaining about. The machine shop I work for has that same generator and it works just fine. a few times we have had power failures, and ran like 8 cnc machines as well as air conditioners, lights,compressors,etc... yeah its loud.

[murymann]

Yes, I would indeed.

Thanks for posting this video.

Is it any wonder why people call them SCREAMING *&^% Generac? I've heard the 150KW one at a shopping center screaming and it is louder than loud. There's no excuse for such when in fact a 1800 RPM 200KW of another make isn't bad at all in the way of noise it made.

Thanks for this new post. While I'm sure the poster knows this, I thought I would add a little info. This model uses gear drive from the engine to the generator so the engine can run at 3000 RPM under load and put out more power than if run at 1800 RPM as would be the case if it were directly connected. This model has a 6.8 Liter V10 engine fueled by natural gas. On other models using the same engine it can be forced to 150KW running at a screaming 3600RPM or 70KW and a nice 1800RPM
