Victron energy VBC 12-24-48V Manual page 17

The default values are suitable for most battery systems, so do not adjust
these settings without fully understanding the consequences.
Name
Charge eff. When a battery is charged, energy is lost. The
fact charge efficiency factor compensates for the
lost energy, where 1 is no loss of energy and
0.5 is a 50% loss of energy.
Peukert The Peukert exponent for your battery (refer to
exponent chapter 4.1.2 for more information). Set to 1.00
to disable the Peukert compensation. Contact
your battery manufacturer for the Peukert
exponent.
Temperature This is the percentage the battery capacity
coef changes with temperature.
Current This value will be considered as zero amps, to
threshol ensure that errors are eliminated.
Shunt current The maximum current rating of the shunt.
Shunt The output voltage of the shunt at the
voltage maximum rated current.
Current offset Used to compensate for small errors in current
measurement caused by unwanted offsets
picked up by the measurement cables.
Battery Duplicates the current reading from the top
current level menu. This allows the effects of changes
to the current offset to be observed without
having to navigate the menu hierarchy.
4.3 Alarms
The VBC is equipped with a relay that can be configured to signal alarms;
or when connected to a generator, to automatically start and stop the
generator. Alarms can also be sent to the VPN, which can be configured
to sound an alarm, or control another relay. Each alarm type can be
configured to activate the relay, send a panel alarm, or both. They can
also be completely disabled.
