Sounds like this could happen. The (really) old SW input had an option
to do this. Disconnect this. Do you have the manual? I might but not
nearby now. Good Luck

Wrench,
An off-grid installation of mine from many years ago has is now using
grid power instead of a generator. The utility is telling the
homeowner that they are going to disconnect him because his house is
back feeding 1 amp into their grid power.
I've been retired for many years now and did not do any of the work to
connect the utility power to his Trace SW4024 inverter/charger. The
utility power became available when his son brought in utility power
for his maple sugaring operation in the neighborhood, and the father
connected power to his house to replace his fossil fueled generator
for additional charging into his battery bank. They do not have a grid
interconnect sellback agreement with the utility.
I have no experience with this, but I'm assuming that the utility grid
is seeing power from its input connection to his Trace SW4024. Does
that sound right? If so, is there a simple solution to fix this
problem while continuing to use the grid power through his SW
inverter?
Thanks for any advice that may help.
