For the averages can this meter run in reverse if monitoring the AC side of solar inverters? If not, does anyone have a suggestion for one that can?

No, this meter can not run in reverse.

Does this measure rms or average ac?

This energy meter measures rms.

This seller is selling a device that cannot accurately measure power in a us based household. only one "hot" lead is being measured and a house panel

So use two and add them together.

How many power meters do i need to monitor: phase 1+ n (110v), phase 2 + n (110v), and phase 1 + phase 2 (220v)?

hi it depends on your requirement. You can only use one meter to monitor one of the phase + n . Or you can use three meters to monitor each phase + n .
