3.6 Factory Default Values
Your MS-AE Series inverter/charger uses default values for the adjustable settings (shown in
Table 3-2) that are adequate for most installations. If some of your operating parameters need
to be changed from the default values, the optional ME-RC remote control can be used to make
those changes. To help you determine if you need the ME-RC 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 nonvolatile memory and are preserved until changed - even if DC power
to the inverter is lost (as long as the ME-RC remote is connected). For information on the full range
of settings for each function, refer to the ME-RC Owner’s Manual at www.magnumenergy.com.
Shore Max - This setting ensures the inverter AC loads receive the maximum current avail-
able from the utility or generator power. When the total current used to power the AC loads and
charge the batteries begins to approach the Shore Max setting, the current that was used for
charging the batteries will automatically be reduced.
01 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.
02 LowBattCutOut: This setting determines when the inverter will turn off based on low bat-
tery 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).
03 Batt AmpHrs: This setting allows the user to input the battery bank size in amp hours
which tells the charger how long to charge the batteries in the Absorb charge stage.
04 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.
05 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 bat-
tery banks are not overheated because of a charge rate that is too high.
06 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. On MS-AE models, when two inputs (leg 1 and leg 2) are used, the VAC
Dropout voltage is determined by the sum of the two inputs ÷ 2. For example, if input 1 = 120VAC
and input 2 = 110 VAC, the sum (230) ÷ 2 = 115. In this example, 115 VAC is what the inverter’s
AC input is sensing to determine when to stay connected or disconnect and start inverting.
Using the ME-RC remote also provides the following features:
