Hi MrWizard,
Yup the 951 watts is post Magnum so would include the energy being drawn from the battery bank. Only the air conditioner was running. I'll hope that the Micro Air unit will prevent the Magnum from disconnecting the shore power by lowering the start up surge.
Although PF is not an issue with the autoformer, amperage is. At the lowest voltage measured 95 on the shore power side, 1425 watts becomes 15 amps. I've measured as high as 1900 with ONLY the roof air running.

You measured 951 at the a.c. Coming from the magnum, including the 33 amps load support?
, if so your saying shore power was only 500+ watts, because the magnum was supplying 400+ watts, that is curious
But still over 1000va being used by the ac,
Your awful close to the power limit you set the magnum to use
I'm sure this is why magnum was inverting, if it did not invert the usage would exceed its own calculated VA for amps used with associated voltage drop off incoming voltage
