Itinerant1- thanks again for all of your help in understanding this (and 3 tons too). I spent more time on the phone again yesterday with another Magnum tech. He didn’t seem surprised, and pushed that the problem is I’m not using a generator that’s 2x the kW of the inverter!?!
It’s clear to me that the Magnum algorithm to accept incoming power integrity is not tolerant of the momentary slump that generators have under high current impulses. It also sounds like this design flaw is not limited to just Magnum. I’m a little surprised that they don’t seem to care, and don’t expect that people buy generators snd hybrid inverters assuming they play together better and load support is as simple as addition.
With your help I’ve purchased a larger genny, and turned my Magnum to optimize it’s performance in this respect. I’ll be adding soft starts and then expect I can improve the odds of running AC on the genny (through the Magnum; pass thru, or load support) to where it’s no longer an issue.
This forum is great, thanks again.
