Victron energy BMV-700 Anleitung Seite 15

3.6 Use of alternative shunts
The BMV is supplied with a 500A / 50mV shunt. For most applications,
this should be suitable; however the BMV can be configured to work with
a wide range of different shunts. Shunts of up to 9999A, and/or 75mV
can be used.
When using a shunt other than the one supplied with the BMV, please
proceed as follows:
1. Unscrew the PCB from the supplied shunt.
2. Mount the PCB on the new shunt, ensuring that there is good
electrical contact between the PCB and the shunt.
3. Connect the shunt and BMV as shown in the quick installation
guide.
4. Follow the Setup wizard (section 1.1 and 1.2).
5. After completion of the Setup wizard, set the proper shunt
current and shunt voltage according to section 4.2.5, setting
number 65 and 66.
6. If the BMV reads a non-zero current even when there is no load
and the battery is not being charged: calibrate the zero current
reading (see section 4.2.1, setting number 09).
3.7 Automatic detection of nominal system voltage
The BMV will automatically adjust itself to the nominal voltage of the
battery bank, immediately after completion of the setup wizard.
The following table shows how the nominal voltage is determined, and
how the charged voltage parameter (see section 2.2) is adjusted as a
result.

In case of another nominal battery bank voltage (32V for example), the
Charged Voltage must be set manually: see section 4.2.1, setting 02.
