Hi Smk,
There is a siren song about double conversion, that's for sure. But I've tried the microwave on a 2000 watt inverter and it was not enough "beef". It was mostly miss.
The Microwave gave me troubles when I had the 2500 watt Cobra MSW, too. It mostly would start, but once in a while.....no go.
So I'm pretty much wanting 3000 watts @ 12 volts and PSW. Finding that in a "stand alone" is not so easy.
By the time I pay for a 2nd and/or larger converter, replace the reverse polarity fuses with auto reset breakers (cause double conversion tends to deform them), and buy a 3000 watt PSW, I'm at about the same cost as another brand new Magnum. (assuming Magnum doesn't warranty).
More solar would be nice--but I'd have to give up my Unisolar panels and replace the charge controller. It doesn't appeal to me much.

Second PD9140 and do double conversion into the battery/inverter.
Use one for low power, both for high power. And more solar for the hot days running the air for extended periods.
