A shunt simply gets inserted into the battery negative cable and all loads and charge sources go on one side of the shunt (normally called the "load side" and NOTHING sneaks past it and winds up on the battery side of the shunt except for the battery bank.
All you will need is a short jumper wire the same gauge as your main battery cables
to go from battery negative post to the battery side of the shunt. The negative cable that was on the neg battery post is simply moved to the load side of the shunt.
A Victron BMV-600 is a very, very easy install, the calibration often takes more time than the installation
The Victron BMV-600 comes standard with a 500A 50mV shunt...
