I can, and have, run the roof air from the Magnum. I was hoping the Microair would eliminate the momentary overload (red light on Magnum remote) when starting. However that did not work out. i.e. the inverter still overloads briefly when starting the roof air compressor.
That is surprising, I installed the Micro-Air for the same reason, since its not on a sub panel and runs the whole coach The Magnum would sometimes trip the low voltage disconnect from the startup surge then overload attempting to start the AC itself.
The Microair completely solved that problem and as a bonus allows the A/C to startup and run off batteries (for about 30 minutes), plus it much easier on everything during startup.
What do you have the AC disconnect voltage set at? I went down to 60v which is the minimum on the Magnum since its so sensitive (one cycle at disconnect voltage) and let my Surge Guard worry about LVD as its less sensitive. If you have the Magnum set most sensitive (UPS mode) it will trip over any slight anomaly.
Hope Mex gets well soon.
