I have a backup array of accumulators that I disconnect from my grid with a power switch (for turning my coal miners back on for backup power if I brownout). When I disconnect them, they act like they are discharging and the surveillance center is the consumer. This is despite it being on a completely different grid. It only seems to apply to the one that's been there a while, when I try to reproduce with a new accumulator I don't see the same behavior.
