DIY Manual
Got Comm?
1. Boot Jumper installed – This causes the Classic to halt the boot-up process and the MNGP
displays GOT COMM?
2. Classic MNGP Port - Can use either the top or middle jacks. If using the middle jack – no
updates and will lose green and yellow MNGP LEDs.
MNGP Reset
1. Under MISC/MNGP/EXTRAS, type in 1-4-2 and pick YES.
2. If you enter the password in MNGP, that resets the MNGP.
3. If you enable password in Tweaks, that password-protects the entire Classic (same PW
used, 1-4-2).
MNGP Cable Info
1. Limited to about 15 ft due to the 9V power supply.
2. Best to use a 6-pin, RJ12 cable.
3. An RJ11, 4-wire cable will work, but you will lose the green and yellow LEDs on the left of
the display.
a. Green if turned on = FLOAT
b. Yellow if turned on = Current Limit
Over-Current Protection protects the Classic from damage. Reasons for OCP activation:
1. Bad inductor inside the Classic. (Repair needed)
2. Bad or weak battery; bad or faulty wire connection. (Corrosion / high resistance / loose)
3. Classic sharing the inverter battery cables. (Classic connected to battery bus bars near
the inverter)
4. Cables and/or wires for the inverter or Classic are too small. This can cause surges in the
inverter to attempt to pull more current from the Classic that it can provide.
5. If OCP does not activate fast enough, transistors in the Classic will be damaged. (Repair
needed)
Factory Reset
Soft - Resets all settings to factory defaults; VMM (Vulcan Mind Meld, for 2-finger application)
1. Write down any custom settings for reference prior to resetting the Classic.
2. Turn the battery and solar power to the Classic off.
3. Depress both Left and Right arrows.
4. Turn the battery power back on.
5. Hold the arrows until the first screen pops up (Charging Source: Solar, Wind, Hydro).
