Operation
3.8 Factory Default Values
The ME Series inverter/charger uses default values for the adjustable settings (Table 3-2) that are
adequate for most installations. If operating parameters need to be changed from the default values,
an optional remote control/display can be used to make those changes. To help you determine if
you need the a remote display, information on the inverter/charger settings that can be changed
is provided below. The settings, once programmed, are saved in the remote’s non-volatile memory
and are preserved until changed—even if DC power to the inverter is lost (as long as the remote
is connected). For information on the full range of settings for each function in your remote, refer
to its owner’s manual at www.magnumenergy.com.
• Shore Max/Input Amps: This setting ensures the inverter AC loads receive the maximum
current available from the external AC input (utility power or generator). When the total
current used to power the AC loads and to charge the batteries begins to approach this
setting, the current that was used for charging the batteries will automatically be reduced.
• Search Watts: This setting allows you to turn off the power-saving Search mode circuitry
or adjust the power level at which the inverter will “wake up” and start inverting.
• LowBattCutOut: This setting determines when the inverter will turn off based on low
battery voltage. The inverter turns off automatically after the battery voltage has been
below this setting for more than one minute. This protects the batteries from over-
discharge and the AC loads from unregulated power (brown-outs).
• Batt AmpHrs/Absorption Time: This setting allows the user to input the battery bank
size in amp hours or to set the absorption time, which tells the charger how long to charge
the batteries in the Absorb Charge stage.
• Battery Type: Sets the type of batteries being used in the system; this information tells
the charger what voltage level to use to charge the batteries.
• Charge Rate: This setting can be used to turn off the charger, limit the amount of current
that the charger can use (leaving more current available to power loads); or, to ensure
small battery banks are not overheated because of a too high charge rate.
• VAC Dropout: Sets the minimum AC voltage that must be present on the AC input before
the unit transfers from Standby mode to Inverter mode. This protects the AC loads from
utility power outages and brown-outs.
Using a remote control/display also provides the following features:
• allows you control to enable an equalize charge for certain battery types
• displays inverter/charger’s operating status
• provides fault information for troubleshooting
