5.2 Operating the Inverter/Charger
Turning the inverter on: Press the ON/OFF pushbutton to activate the in-
verter function. The inverter will either be actively inverting by using power
from the batteries to power the AC loads (see fi gure 5-4); or will be searching
for a load by using very little power from the batteries - if in search mode
(see fi gure 5-3). The green 'INV' LED will be on when the inverter is actively
inverting and the green 'INV' LED will fl ash while searching.
Turning the inverter off: While the inverter is actively inverting or search-
ing, the ON/OFF INVERTER pushbutton can be pressed to switch the inverter
function off and this will turn the green 'INV' LED off (see fi gure 5-2).
Inverter Standby: The inverter is in standby when the inverter is active
(green 'INV' LED is on) and an external AC power (utility/shore or generator) is
passing through the inverter to power the AC loads. During normal operation,
the AC loads will be powered by the external AC power, however, if a blackout
or brownout condition occurs, the inverter senses these conditions, transfers
to inverter mode and powers the AC loads connected to the inverter.
CAUTION: If you have critical loads and in Inverter Standby, do not
press the ON/OFF pushbutton to turn the inverter function off. If the
green 'INV' LED is off, inverter power will NOT be available to run
your critical loads if the external AC power is interrupted.
Equalize charging: Equalizing is a controlled-overcharge performed after the
batteries have been fully charged. It helps to mix the battery electrolyte (to
reverse stratifi cation) and also helps to remove sulfation that may have built
up on the plates. These conditions, if left unchecked will reduce the overall
capacity of the battery.
WARNING: Do not perform an equalization charge without reading
and following all safety precautions pertaining to charging/equaliza-
tion as noted in this manual and any equalization information in the
inverter's manual.
To enable the equalization charge; see fi gure 5-10 and follow all related
information on page 25.
5.3 System Status Messages
The remote control uses the top line of the LCD display to show the inverter/
chargers operation by displaying a status message. This section will show
the inverter/charger's operating modes and the available status messages
under each mode. Use these status messages along with the Status LED's
to determine the inverter/charger's current operating status and to help
troubleshoot the system if a fault occurs.
There are three operating modes of the inverter/charger:
• Inverter Mode
