System Voltage: The system voltage is the output
voltage of the generator set. Default values are shown
in Figure 3-5. The system voltage is set to the
required output voltage to properly support the load
and charge the battery. Do not confuse this value with
the voltage designation of the battery stack.
example, four 12V batteries in series results in a 48V
battery stack, but the output voltage needed to charge
the battery stack is 54V.

voltage needs to be changed, see the Operation
Manual for instructions to change settings.
Note: Setting the system voltage to a higher value
than the factory default setting will decrease the
power output of the generator set.
A 6VSG set at the system voltage shown in Figure 3-5
will have an output of 6 kW. If the system voltage is
set to a higher value, the output current decreases.
The available power output also decreases below 6
kW due to the limits on the engine speed. The graphs
in Figure 3-7 illustrate the effect of changing the
system voltage.
Auto Start Volt: The 6VSG will automatically start
when the battery bank voltage has reached or fallen
below this value for 180 seconds (3 minutes). Default
settings are shown in Figure 3-6.
