Operating the Inverter/Charger
5.2.1 Inverter
Mode
Turning the inverter on:
Press the ON/OFF INVERTER button to activate the inverter function.
The inverter will either be actively “inverting” by using power from the batteries to power the AC
loads; or, the inverter will be “searching” for a load by using very little power from the batteries,
if in Search mode. The green INV LED is on when the inverter is actively inverting, and the green
INV LED
fl
ashes while searching.
Turning the inverter off:
While the inverter is actively inverting or searching, press the ON/OFF
INVERTER button to switch the inverter function off. This turns the green INV LED off.
Inverter Standby:
The inverter is in Inverter Standby mode when enabled (green INV LED is
on) but not actively powering AC loads from the batteries. If in a standalone system, the inverter
is in Inverter Standby when the charger is active (i.e., Charge mode). In a parallel system,
inverter standby occurs to the slave inverter when it is monitoring the power requirement of the
parallel system to determine when to activate and provide power to assist the master inverter.
5.2.2
Charger Mode
Turning the charger on:
Charge mode is automatically activated and begins when acceptable
AC power (utility or generator) is connected to the input of the inverter. When in Charge mode,
the display may show:
Absorb Charging, Bulk Charging, Charger Standby, Charging
,
Equalizing,
Float Charging
,
Full Charge
,
Load Support AAC
,
Load Support VDC
, and
Silent
. (When the charger
is ON and actively charging, it produces DC voltage and current to charge your batteries, and the
CHG LED is solid.)
CAUTION:
If you have critical loads and are in Charge mode, do not press the ON/OFF
INVERTER button, or you may inadvertently turn the inverter function off. While in any
Charge mode, ensure the green INV LED is ON, or inverter power will NOT be available
to run your critical loads if the external AC power is interrupted.
Charger Standby:
While the charger is actively charging, press the ON/OFF CHARGER button
to switch the charger to Charger Standby. When in Charger Standby, the incoming AC is still
available on the inverter’s output, but the charger is not allowed to charge. The LCD displays
“Charger Standby”
and the CHG LED
fl
ashes.
Info:
To resume charging, momentarily press the ON/OFF CHARGER button or
disconnect/reconnect AC power to the inverter’s input.
Equalize charging:
Equalizing is a ‘controlled overcharge’ performed after the batteries have
been fully charged. It mixes battery electrolyte (to reverse the buildup of strati
fi
cation) and
removes sulfates that may have built up on the plates. These conditions, if left unchecked,
reduces the overall capacity of the battery. To enable the Equalization charge, see pages 60-61.
WARNING:
Do not perform an Equalization charge without reading and following all
safety precautions pertaining to charging/equalization as noted in this manual and
provided by the battery manufacturer.

System Status Messages
A status message may be an operational or fault message indicating the inverter/charger’s current
operating status. This section covers the inverter/charger’s operating and fault modes, and the
available status messages under each mode.
Use the displayed status message and the status LEDs on your router to determine the inverter/
charger’s current operating status, and to help troubleshoot the system if a fault occurs.
The ME-ARTR has four Home screens: a System Home screen, All PORTs Home screen, Individual
PORTs Home screen, and an Accessory PORTs Home screen (see Figure 5-3). Each display shows
pertinent information about any attached devices or accessories, as well as their current operating
status. The router’s FAULT LED
fl
ashes if one of the devices/accessories has a fault (see Sections
5.3.4 & 5.3.5 for information on identifying and resolving faults).
