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 -- Mac Lewis *"Yo solo sé que no sé nada." -Sócrates*
