Factory Default Settings

Your MM Series inverter uses default settings that are adequate for
most installations. However, if you determine that some of your oper-
ating parameters need to be changed, the optional ME-RC50 remote
allows you to control the operation and to customize the programming
parameters of the inverter and/or charger.
To help you determine if you need the ME-RC50 remote*, information
on the settings that can be changed is provided below. The settings
once programmed are saved in non-volatile memory and will be pre-
served until changed – even if DC power to the inverter is lost (the
ME-RC50 must always be connected).
Search Watts: This setting allows you to enable the power-saving
Search Mode circuitry and to adjust the power level at which the
inverter will "wake up" and start inverting. This function is not
available on the MM612 model and is adjusted to 5W ("wakes up" and
inverts if loads exceed 5 watts) on the MM1212.
LBCO: This setting determines when the inverter will turn off based
on low battery voltage (inverter turns off automatically after 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).
Battery AmpHrs: This setting allows the user to input the battery
bank size in amp hours, which provides information to the charger on
how long to charge the batteries in the Absorb Charging stage.
Battery Type: Sets the type of batteries being used in the system
which provides information to the charger to determine what voltage
level to charge the batteries.
Charge Rate: This setting uses a percentage of the charger's max.
output to determine the output charge rate. This setting can be used
to 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 min. AC voltage that can be present on the
AC input before the unit transfers from Transfer Mode to Invert Mode.
This protects the AC loads from utility outages and brown-outs.
