Schneider Electric XW+ inverter zeroing out the small power consumption when on grid support

neutronspin

I know on the Schneider XW+ that when in Grid Support mode there is always a small amount of grid power drawn no matter what.....usually less than 100 watts.  Is it possible to put the inverter on Sell-back mode and set sell back to zero?.....Would this eliminate the small amount of grid consumption?.....thanks.....
