Operating The Inverter/Charger; Inverter Mode; Charger Mode - Magnum Energy ME-RC Owner's Manual

5.0 Operation

5.2 Operating the Inverter/Charger

5.2. Inverter Mode

Turning the inverter on: Press the ON/OFF INVERTER pushbutton to activate
the inverter function. The inverter will either be actively "inverting" by using
power from the batteries to power the AC loads (see figure 5-4); or will be
"searching" for a load by using very little power from the batteries - if in search
mode (see figure 5-3). The green 'INV' LED will be on when the inverter is
actively inverting and the green 'INV' LED will flash 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 figure 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 INVERTER 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.

5.2.2 Charger mode

Turning the charger on: The charger will automatically be activated and
begin to charge your batteries when acceptable AC power (utility/shore or
generator) is connected to the input (HOT IN 1) of the inverter. When the
charger is ON, it produces DC voltage and current to charge your batteries.
The CHG LED will be on when the charger is ON and actively charging. While
charging the display will show Bulk, Absorption, Float or Full Charge (see
figures 5-5 thru 5-9).
Charger Standby: While the charger is actively charging, the ON/OFF CHAR-
GER pushbutton can be pressed to switch the charger to "Charger Standby".
While the charger is in Charger Standby, the incoming AC is still available on
the inverter's output, but the charger is not allowed to charge. The display
will show 'Charger Standby' and the CHG LED will flash when the charger is
in standby mode, (see figure 5-10).
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 helps to mix the battery electrolyte
(to reverse the buildup of stratification) and also helps to remove sulfates
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 figure 5-11 and follow all related
information on page 26.
