[RE-wrenches] Generac QT series

[Mac Lewis]

Hello wrenches,

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.

Thanks in advance
