Guys,
   
   I have called this in but missed Roy's phone call and I have been talking to Jim also.
Bottom line is 1 of  my 3 Classics is showing a Yellow and Green LED on the Left panel
and has quite charging! Jim recommended I update the Firmware to latest and I did a
reset holding the left and right arrow buttons when I powered up. Not sure what is going
on but the problem is still there! My other (2) 150's are working fine. I have a 48 VDC
system and am reading 110.7 volts input from the panels on the bad controller. It now
has the latest firmware and the problem still exist. Got any ideas? Perhaps it's time for
an RMA?  FYI, this charger has 12 - 250 watt sharp for 3KW about 60% of it's capability.

   Thanks for your help,

   Bill  West TN

The yellow and green LEDs are driven by the classic itself and not the MNGP remote.

If the processor is bad, that could cause this LED staying on problem but since you
are reading PV voltage on the MNGP and were able to update the Classic's firmware,
the processor must be working.

What else does the MNGP say on the status screen ?  Resting ? What is the battery voltage
reading on the Classic ?  What is the Classics' charge setpoint voltage ?
Does this Classic behave differently if you tun off the other 2 Classics ?

If it says Resting, I wonder what the Reason For Resting number is also ?

There may be some more clues here.
