Capacitors make no difference whatsoever to the wattage consumed. You

   Not for a conventional watt hour meter. But an electronic wattmeter
that does time of day measurements might be entirely different. Perhaps
it measures and amps and volts so it measuring VAHours. I don't know...
Who knows the answer to that? Glad I don't have one!

Normally I believe PF is corrected at the substations.

 VA X Hr. are not legal to bill on in N.America. The PF
correction does not, and cannot, affect kWh consumption
directly.

However I believe their is more to the story but Jim
doesn't seem to want to hear it.

If you PF correct your loads on your Inverter then the
VA used to supply those watts to your loads decreases
(better pf). Since power sources really are rated in VA
and not watts (contrary to popular misconception) the
inverter now has more VA capacity left to supply back
into the grid reducing watts/watthours consumed via the
utility meter.

In California, PG&E does use kWh and rkVAh meters.
The bills are adjusted to kWH.
