[RE-wrenches] Generac QT series

Tue Dec 16 10:15:44 PST 2014

If memory serves me correctly and this is the off grid Generac they are available as a 120 volt and it takes a new breaker and rewiring to get 120 / 240 out of them

I run into this in the past they actually had it wired for 240 into a balancing transformer to feed 120 into the inverter

We could've just left it at 120 volt 

Later,

>>> We have a newly installed system that has a 22 kW Generac Quiet Source QT02224GNAX with a Magnum MS4448-PAE.  When we start the generator, the Magnum's internal transformer temperature climbs to overtemp (240F) within a 2 minutes.  The batteries are being floated at the time, and haven't seen more than 5A coming out of the generator.  We swapped the Magnum out, and we have the exact same issue.  We then got a job-site gas generator 6500W and ran it.  No problem whatsoever.  The problem appears to be with the Generac, or with the interaction between the Generac & the Magnum.  I didn't have a scope on site but the fluke multimeter doesn't detect anything wrong with the voltage or frequency coming from the Generac.

>>> Has anyone had issues with the Generac QT?  Anyone paired one with a Magnum PAE before?  I want to get my scope up there and look for triplen harmonics, but I'm not sure how to filter these out.  Any references on how to effectively do that is appreciated.
