*Verify the charging mode is correct for the source as well as the “Mode” is on
Classic switches
between Resting and
Bulk MPPT repeatedly
but produces 0 watts
*This can be normal under low light conditions.
*Watch the input voltage, if it drops down close to battery voltage and then the
Classic goes to Resting this is usually a sign of a bad connection. If it is rock
solid call customer service
*Try doing a factory restore. (Warning all settings will be lost)
The Display shows 0
volts in (or really close)
but shows battery
voltage correctly
*If this is a new install check for reverse polarity on the PV positive and
negative on the blue terminal block inside the Classic
*If the system has been running all along and this just happened call customer
service.
The Display is showing
all 0s and or “Got
Comm”
*Make sure you did not put a different display on the Classic, Firmware must
match on the Classic and MNGP.
*Do a HARDWARE Factory Restore (See manual)
The Display is showing
“Mode is OFF”
*Enter the main menu and select “Mode”. Turn the Mode “ON” ad press Enter
to save this. Then press Status to return to the main screen.
*If using the Classic for wind and you cannot turn the mode on this can also
indicate the wind curve is not linear and the classic cannot work with it. Please
make sure the wind curve continually goes up hill.
Stuck in the Quick Start
or “VMM”
*Check that the blue display cable is plugged in and connections are sound.
Try unplugging it and plugging it back in. Check for corrosion also.
*Do a HARDWARE Factory Restore (See manual)
The MNGP (Display) is
fuzzy or has odd
characters
*Check to make sure the blue display cable is plugged in well and that it is not
running down over the 2 big yellow inductors on the left hand side of the
circuit board.
Multiple charge
controllers and one or
more is showing 0 watts
and absorb or float
*This is normal as the battery is almost full and the extra power is not needed
so the controller throttles back to prevent over charging of the battery
Multiple Classics in
Follow Me and they are
not all making the same
amount of power?
*This is normal as Follow Me simply coordinates the charge stages, each
Classic still works independently as far as regulating the PV array.
How do I verify Follow
Me is working properly?
*You should first go to the Main menu and then into the “Temps” menu and
verify all controllers are seeing the Battery Temp from the one with the BTS
plugged in.
*You should also see a blue LED flashing inside the top vent. There are two
types of blink, A short blink that is about one tenth of a second means it is
getting good information. A long blink that is about half a second indicates it
did not get any info. If the blinks are ALL long then you probably have a bad
cable and all cables should be checked immediately
The Fans seem way to
loud
*If it is the internal fans make sure no wires or anything have come in contact
with them inside the wiring compartment
*If it is the external fan you may want to remove the front half of the “Turbo”
plastic housing and make sure the fan is still adhered into the back plastic
housing. If the fan has come loose a dab of silicone on each side should solve
the noise issue. Please make sure not to get any silicone on the fan blades
