Operation

3.8 Factory Default Values

Your MS 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

available 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 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).

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 battery 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.

Using the ME-RC remote also provides the following features:

allows you to enable an equalize charge for certain battery types.
