A-2 Inverter Effi ciency
The following curves are plotted to show the MS Series’ effi ciency over the full power range and is
displayed as a percentage. This graph represents the inverter’s effi ciency while operating resistive
loads. Motors and other inductive loads run less effi ciently due to the impact of power factor losses.

A-3 AC Input Voltage to Output Charge Amps
The following chart shows the expected charger output capability of the MS Series. The maximum
charge current is dependent on the AC input voltage and the inverter battery voltage. Note: The output
charger current shown is with the inverter battery voltage at nominal (i.e., 25.2 volts for MS4024).
