Monitoring the LED Indicators
The remote’s front panel uses LED indicators to show the status of
the inverter system. These LED indicators automatically switch be-
tween the inverter or charger mode (MM-RC only) as the operation
of the inverter system changes.
The LED status indicators show four modes of system operation:
• INVERT - Invert Mode status
• AC IN - Transfer Mode status
• FAULT - Fault Mode status
• BULK, ABSORB or FLOAT (MM-RC only) - Charge Mode status
Info:
To understand more about the operating modes
of the inverter or charger, refer to the MM/MM-AE Series
inverters’
Owner’s Manual.
MM-R and MM-RC Remotes
The three LED indicators on the left side of both the MM-R and MM-
RC remotes (
s
ee
Figure 7)
will show you the operating status of the
MM/MM-AE Series inverter.
Monitor these indicators to determine
the inverter’s mode of operation:
INVERT
(green)
-
• On (solid)
– and
AC IN
LED indicator is Off: The inverter is On. It is
using energy from the battery to supply AC power to the loads
connected to the inverter.
– and
AC IN
LED indicator is On (solid): The inverter is in
Standby. The external AC power (utility or generator) connected
to the inverter’s input is passing through the inverter to power the
AC loads. The inverter will automatically turn on to power the AC
loads if the external AC power is lost or disconnected.
• Blinks On (once every second) – The inverter is in Search Mode.
The AC load is below 5 watts (Search Watts default setting).
• Off – The inverter
is disabled. The inverter is not on or will not
come on if AC power is lost or disconnected.
AC IN
(green)
-
• On (solid) – the external AC power (utility or generator) is
connected to the inverter’s input and passing through the inverter to
power the AC loads connected to the inverter’s output.
• Blinking On (once every second) – the external AC power is
present but not actively being used. Either: 1. The AC input is being
quali
fi
ed (takes approximately 15 seconds) or, 2. The input AC
voltage is low. Ensure the incoming AC voltage is above 90 volts
(VAC dropout setting with the MM remote connected).
• Off – No external AC po
wer is detected on the inverter’s input.
