State of charge
information When a DC Monitor is installed, you can monitor the batteries’ state of
charge on the System screen or inverter/charger menu.
Outcomes If you set “Start SOC” too high, the generator will start more frequently
than is convenient.
If you set “Start SOC” too low, your batteries may be damaged by
repeated cycles of excessive discharge. The generator running time
necessary to charge the batteries may exceed the Generator Run Max
Time, and use too much fuel in the process.
Start DCV
Full name Starting Battery Voltage—30 seconds
Purpose “Start DCV” is a changeable setting that enables the Auto Gen Start to
start the generator whenever the battery voltage reaches a pre-set voltage
for longer than 30 seconds. You can also select the desired battery voltage
with this setting.
The Auto Gen Start will stop the generator when the battery voltage has
risen to the Stopping Battery voltage (see “StopBattV” on page 3–22), or
when the batteries have been recharged to the Absorption or Float stage.
This setting requires you to set either “StopBattV”, or a Stop at Charge
Stage setting (see “Stop Float” on page 3–26 and “Stop Absorb” on
page 3–25).
When to use If the Auto Gen Start is set to Automatic mode, then the Auto Gen Start
will start the generator when the system battery voltage (as measured by
the inverter/charger or DC Monitor) falls below the “Start DCV” setting
for the selected delay period.
You can use the “Start DCV” setting when there is no accurate, reliable
battery state of charge monitoring available, such as from the Xantrex DC
Monitor.
Battery voltage
information During normal operation, battery voltage can be monitored from the
System screen or on the inverter/charger menu.
