Factory Default Settings

Your MM Series inverter uses default settings that are adequate for most
installations. However, if you determine that some of your operating
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 preserved 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 and MM1212-G models.
• LowBatCutOut: 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 maximum
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 minimum 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.
