Make sure you are in FLT mode and not SELL mode. Or Make sure grid is hooked up to AC 2 if only used for battery charging. FLT mode should only offset grid usage but not sell excess. Refer to the Manual

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

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.
