RD Series Owner's Manual - Magnum Energy

Operation
3.8 Factory Default Values
Your RD 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, the optional ME-RC50 remote control can be used to make those changes. To
help you determine if you need the ME-RC50 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 ME-RC50 remote is connected). For information on the full range of settings
for each function, refer to the ME-RC50 Owner’s Manual at www.magnumenergy.com.
• Shore: This setting ensures the inverter AC loads receive the maximum current available
from the utility power or generator. When the total current used to power the AC loads
and to charge the batteries begins to approach the “Shore” 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 overdischarge
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 too high charge rate.
• 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 power outages and brown-outs.
Using the ME-RC50 remote 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
