5.3.1 Inverter Mode Status Messages
There are six Inverter mode messages. View the top line of the LCD display and the correspond-
ing message in this section to identify 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 invert-
er 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 not receiving any communication data via the Magnum
Network.
Remedy: Disconnect the remote communications cable from the inverter for fi ve
seconds, and then reconnect to reset the remote (see Figure 2-2). If the fault continues,
examine the remote cable for damage, and replace if needed (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: 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 20).
• Unknown
Mode ## – This status message displays when the inverter/charger has sent an
operational status code that the ARC remote does not identify.
Remedy: Call Technical Support at Magnum Energy (425-353-8833) for assistance in
identifying and understanding the actual fault status.
5.3.2 Charger Mode Status Messages
When AC power (utility or generator) is connected to the inverter/charger, it begins to monitor
the AC input for acceptable voltage. Once the AC input is accepted, the AC transfer relay (inside
the inverter) closes and charge mode begins. There are ten Charger mode status messages. View
the top line of the LCD display and the corresponding message in this section to identify and un-
derstand the particular Charger mode.
Info: The AC input becomes acceptable once: a minimum 10-second delay passes and
the voltage is greater than the SETUP: 03B VAC Dropout setting, or no CTRL: 01 AC In
Control menu setting is enabled and actively preventing the AC from connecting.
• Absorb Charging – The Absorb charge state is the constant voltage stage and begins when
the absorb voltage is reached (determined by the SETUP: 03C Battery Type setting) while Bulk
charging. During this stage, the DC charging current decreases in order to maintain the absorb
voltage setting. This charge stage continues until the 03D Absorb Done (Time, Amps, or SOC) or
the 03F Max Charge Time setting is reached.
• Bulk Charging – The battery charger is delivering maximum current (determined by the
SETUP: 03E Max Charge Rate setting) to the batteries. The charger remains in Bulk charge until
the absorb voltage (determined by the SETUP: 03C Battery Type setting) or the 03F Max Charge
Time setting is reached.
• Charger Standby – This indicates the charger has been disabled to prevent further charging,
but the AC power (from utility or generator) to the AC input is still available on the AC output.
This display is shown when the ON/OFF CHARGER button is pressed while the AC power is passing
through the inverter/charger.
