SW firmware upgrade flourescent flicker [RE-wrenches]

[Jerry Caldwell]

Wrenches,

I have a customer who had his pre-GTI Trace SW
inverters retrofitted with the new anti-islanding
software.  He claims that ever since the upgrade his
flourescent lights powered by the backed up loads
panel have a flicker that pulses about once every
second.  Sometimes the flicker is worse than other
times.

Since the anti-islanding software is supposed to
disconnect and reconnect to the grid once per second,
I can't help but wonder if my customer isn't justified
by blaming the software upgrade.

Has anyone had or heard of similar experiences?  And
better yet, does anyone have ideas to solve this
problem?  I want to keep this customer relationship in
good standing.
