Forgot to say that if the inverters ARE grid tied, then they will NOT
drift around in phase and will
be synchronized and therefore will stay in sync and be passing through
from grid to output.

You can test to see if both inverters are staying in sync by just
watching the voltage between L1 and L2 of the
outputs for a while. If they do not deviate much from 240VAC over
several minutes, then they are probably
sync'd OK... You can also help verify this by unplugging the sync
Well l would start simple and get a sync cable and make sure that they are
al least staying g in correct phasing, then look closely at the
programming, look at the grid voltages and settings, take it out of IEEE
for test purposes only, you might find out you have a board that's out of
calibration
