06 VAC Ropout
80VAC
 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 Low Battery Cut Out Voltage - 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 (see “Max Bulk and/or Discharge Current”) - 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. On MS-PAE models, when two inputs (leg 1 and leg
2) are used, the VAC Dropout voltage is determined by the sum of the two inputs ÷ 2. For
example, if input 1 = 120VAC and input 2 = 110 VAC, the sum (230) ÷ 2 = 115. In this
example, 115 VAC is what the inverter’s AC input is sensing to determine when to stay
connected or disconnect and start inverting.
