5.3 System Status Messages
A status message may be an operational or fault message indicating the inverter/
charger’s current operating status. This section will cover the inverter/charger’s
operating and fault modes, and the available status messages under each mode.
Use the displayed status message and the status LED’s on your ME-ARC remote
(Figure 5-2) to determine the inverter/charger’s current operating status, and to
help troubleshoot the system if a fault occurs.
There are three modes of operation for the inverter/charger:
• Inverter mode • Charger mode • Fault mode
Refer to the appropriate section to locate information on any particular
status message.
5.3.1 Inverter Mode Status Messages
There are several Inverter mode messages. View the top line of the LCD
display and the corresponding message in this section to determine and
understand the particular Inverter mode.
• Inverting
– The inverter is providing AC voltage on its output by
inverting power from the batteries.
• Inverter
Standby
–
The inverter is on but not actively providing power.
However, the inverter remains active and an external AC power (utility or
generator) is passing through the inverter to power the AC loads.
• No Inverter Comm
– The remote is no longer receiving any
communication data via the Magnum Network.
Remedy:
Reset the remote by disconnecting the remote commu-
nications cable from the inverter for
fi
ve seconds, and then recon-
nect (see Figure 2-2). If the fault continues,
fi
rst check/replace the
remote cable (4-wire telephone cable).
What if the cable is not the issue?
•
Try another remote display
•
Reconnect the remote from the Remote port to the Network port
•
The inverter may need servicing
• Off
– This message tells you that there is no AC available on the
inverter’s AC output. The inverter function is OFF and there is no utility or
generator AC power sensed on its input.
• Searching
– The inverter is in Search mode. This means the AC loads
on the inverter output are less than the SETUP menu’s
02A Search Watts
setting. The Search mode function is used to reduce the inverter draw from
the battery, and may be turned off at any time if you want full inverter
output voltage available at all times (see 02 Invert Setup on page 23).
