I've removed your picture and modified the serial numbers (They show up on MAC address) for it just to be extra safe. Attached is the modified picture. I would feel safe posting something like this with the S/N's blacked out.
Regardless, your last post's suspicions are probably the answer here;
I forgot to mention: I have a 12 kWh battery setup, and an Outback Radian inverter. Is it possible the negative numbers are caused by my exporting power back to the grid, or by something more nuanced, as to power flow from batteries to the house or I don't know what?
Specifically, the last part of the post. There have been a number of people with battery set ups that have either an inability to monitor both directions of the battery's flow (without an increase in the amount of hardware used) or have it negatively effect their load somewhere in the system. This is a byproduct of innovation in the renewable energy sector that was not readily available at the time of development for the software used in Footprints. I would suspect, that in those moments your system is reading negative, your battery is feeding the panel enough to swing the numbers. I would be curious to see what the MTUs are reading when Commander is showing a negative swing. That would tell us something!
