Here you go.   See if it measures around 10 Ohms.   R145  is a 1206 size SMT resistor.

We have seen some of these go open.  When that happens, the PV in will not move hardly at all, if any, from Voc but the display will show MPPT.

The 0005 watts is probably just a measurement tolerance.

Not sure if this is the problem but it certainly will not hurt to measure it if you have an Ohm Meter

open a repair ticket at midnite - they sometimes have loaner controllers I think while something is being repaired.

Just going to continue running it because its still charging my battery and buy a different charge controller like a victron when i have money i am in Jamaica and it is not profitable for me to send it back for repair that money could make up and buy a new charge controller

If it is just MNGP messing up - have you used computer or android to try to monitor it and see what the status is showing ?
I forget which model Classic you have and if it is one with modbus .

Yes if you could check like the local app or my midnite and see they are reporting we could send an MNGP
