Factory Default Values
Your MS-PAE Series inverter/charger uses default values for the adjustable settings (shown in
Table 3-2) that may be adequate for your installation. If some of your operating parameters need
to be changed from the default values, the optional remote control can be used to make those
changes. To help you determine if you need a remote display, information on those 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, refer your remote owner’s manual at

• Shore
Max/Input
Amps
– This setting ensures the inverter AC loads receive the maximum
current available from the utility or generator power source. When the total current used to
power the AC loads and charge the batteries begins to approach the
Shore Max/Input Amps
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
– This setting allows the user to establish the battery bank size in amp/hours,
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.
A Magnum remote also provides the following features: allows you to enable an equalize charge
for certain battery types, displays the inverter/charger’s operating status, and provides fault
information for troubleshooting.

* These default values are without a remote connected. If a remote is connected, the remote settings
are saved in the inverter even if the remote is disconnected—until all power to the inverter is removed
or a soft reset is performed.
