Hi Mac, Jay just had the same issue and it was 120v from the gen instead of 120/240. The inverter was charging using half the windings causing it to Overtemp.
Check the 60A breakers on the side of the inverter. Also make sure to remove the wires from the input terminal block before measuring voltage as the inverter will make 120v look like 120/240v at the terminals. If the generator is 3 Phase it won't work with this inverter unless you only use one leg. This will work but you will need to turn the charge rate to 50% in order to prevent Overtemp. Sometimes it works as high as 70%.

I believe the Magnum is a 120/240 VAC.

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.
