Factory Default Values

The MSH3012RV inverter/charger uses default values for the adjustable settings (shown in Table
3-2) that are adequate for most installations. If some of the operating parameters need to be
changed from the default values, an optional remote control/display can be used to make those
changes. To determine if you need a remote display, information on the inverter/charger settings
that can be changed is provided below. Once programmed, the settings 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). See Section 3.9 for additional information.
For information on the full range of settings for each function in your remote, refer to its owner's
manual at www.SensataPower.com.
• Shore Max/Input Amps: This setting ensures the inverter AC loads receive the maximum
current available from shorepower or a generator. 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 to 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).
• Absorption Time: This setting allows the user to determine 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
shorepower outages and brown-outs.
Using a remote display also allows you to enable an equalize charge for certain battery types,
displays inverter/charger's operating status, and provides fault information for troubleshooting.
The table below provides the inverter's default settings—without a remote control 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.
