When to use In Automatic mode, the Auto Gen Start will start the generator when the
system battery voltage (as measured by the inverter/charger) falls below
the “StartV:15min” setting for 15 minutes.
You can use one of the Starting Battery Voltage settings (“StartV:30sec”,
“StartV:15min”, “StartV:2hr”, and “StartV:24hr”) when there is no
accurate, reliable battery state of charge monitoring available, such as
from the Xantrex DC Monitor.
Battery voltage
information Battery voltage can be monitored from the System screen or the inverter/
charger menu.
Whenever the generator starts automatically based on the Starting Battery
Voltage, it will stop when the battery voltage reaches the “StopBattV”
setting. If you have enabled “Stop Float” or “Stop Absorb”, the generator
will stop when the Absorption or Float stages of the battery charging
begin.
Outcomes If you set the Starting Battery Voltage too high, the generator will start
more frequently than is convenient.
If you set the Starting Battery Voltage value too low, your batteries may
be damaged by repeated cycles of excessive discharge. The generator
running time necessary to charge the batteries may exceed “Max Run
Time”, and use too much fuel in the process.
StartV:2hr
Full name Starting Battery Voltage—2 hours
Purpose “StartV:2hr” 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 2 hours.
This setting requires you to set either a Stopping Battery Voltage, or a
Stop at Charge Stage setting.
