August,
It appears in reading the installation manual that with a power factor of .64, that 6 KW system can theoretically produce a dynamically adjustable combination of active and reactive power up to 9.37 KVA however the KW will remain the same at 6 KW. I sped read the manual so I may have missed something.
Your 10 KW system at a .999 power factor (assumed) could theoretically produce 10.01 KVA.
IMO if all you are using is the real (or active) power, then the other system would need to be increased in size from 6 to 10 KW to be an equal comparison.
SMA is suppose to have inverters coming on the market in the US soon (originally fall 2010) that also have the ability to produce reactive power.

Hi All -
Have any of you heard of the Xslent XPX-A1000 microinverter?

We're going up against them on a 10 kW system and I'm trying to figure out
if their claims about producing reactive power mean anything to us in the
real world. They are saying that their 6 kW system will outperform our 10
kW system.
I also noticed that their CEC efficiency is only 89%...
Best,
August
