Classic Charge Controller
Q: Classic MNGP (display screen) Firmware update issues, Why will it not update?

A: • Ensure the MNGP is plugged in using the blue display cable in the top jack of the main circuit board. • Verify you have an MNGP and not an MNLP. The MNLP is an LED panel that comes with the Classic Lite and does not need to be updated. • When the black box pops up telling you to power the Classic up, Count to 4 before turning the breaker on. • If you do not have a breaker or disconnect and you are trying to connect a wire to a terminal block or a battery, the connection will likely be too dirty for the boot loader. Install the proper breakers.
