directly to the AC distribution panel. This module communicates
AC POWER output, consumption and frequency to the G12
MODULE.

above the battery box. The DCM3 monitors the battery status and
communicates it to the G12 MODULE.
The SOLAR CONTROLLER communicates with the G12 panel the
status, type of charge, temperature, panel voltage, charge voltage,
amperage and history of the solar charge.
