All three of our MPPT solar controllers have been showing daily power produced - often a very significant amount. See pic... the problem is... we have been on the hard since hurricane season last year and none of the solar panels have been connected! They aren't even on the boat.
Well it looks like something is connected as the picture is showing that there is 60 odd volts on the PV terminals of the regulator
please check the incoming PV connections on the regulators with a volt meter, and see if there is a voltage reading. if there is then remove the wires and check the regulator terminlas and the to wires coming from the panels.
It's just confused, poor thing. Imagine what it's mpp tracker is doing trying to find a V/I to deliver.
Just isolate it from the batts and let it rest. Good luck too with the next hurricane season..
Another possibility is despite the 'Yesterday', '2 days ago' etc, if the unit is not connected to anything, it has no way to know that days are passing. There is no real time clock/battery inside to keep track, and it depends on the solar panels to know when it is night and day.
The data you might be looking at could be old and from when the unit WAS last connected to solar panels.
