Not sure if anyone else has seen this before, but any thoughts what could be happening?
I'm in the middle of redoing the wiring home runs for my primary array. I have parallel strings on my roof that are still paralleled together, but not connected to an inverter, the wires are just hanging out on the roof disconnected.
I see this from the tigo portal. Is there actually power flow happening somewhere in the array? Do I need to worry that there's a short somewhere? My inverter has periodically reported failures in the arc fault self test but I assumed, maybe wrongly, that it was just a defective part in the inverter.
