Factory Default Values

Your MS-PE Series inverter/charger uses default values for the adjustable settings (see Table 3-2)
that are adequate for most installations. If some of your operating parameters need to be changed
from the default values, an optional remote display can be used to make those changes. To help
you determine if you need a remote display, information on the changeable inverter/charger set-
tings is provided below. Once programmed, the settings 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 display is connected). For information on the full range of settings for each function in your
remote display, 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 utility or generator power. When the total current used to power
the AC loads and to charge the batteries begins to approach the Shore Max 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 to 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 charge rate that is too high.
• 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 outages and brown-outs.
Using a remote display also provides the following features:
• allows you to enable an equalize charge for certain battery types
• displays inverter/charger's operating status
• provides fault information for troubleshooting
Info: Specifi c adjustments that are set using a remote control will be lost if the remote
is unplugged and battery power is shut off to the inverter/charger.
