Standalone solar system, GFCI, and VSD "nuisance tripping"

[pattim]

Are GFCI's sensible or required on the 120VAC inverter output(s) of an island/standalone solar system? (I suspect they are.)

If so, another question: there are classes of newer motorized systems - air conditioners with variable speed compressor drive motors (VSD) are an example - some of which are specifically designed not to be plugged into a "home GFCI outlet" (per the manufacturer). They have their own GFCI on the power cord plug which is resistant to the high-frequency pulses the VSD electronics leak onto the 120VAC line. What should be done about these cases short of having two separate inverters? (one GFCI and the other sans-GFCI)
