Grounding confusion

Hi,

The neverending grounding confusion... Sorry if this was asked before, I searched but couldn't find a fitting answer.


Looking to finalise the grounding of my system, Wiring Unlimited by Victron says to ground closer to the battery negative - makes sense. Here is the schematics they attach in the guide as an example:


Then, I found a guide on this website, called "Grounding basics: stationary systems".

There is says not to ground between the BMS and the battery negative, so I don't be able to mimic Victron's guide from above since I have a daily BMS attached to 16 LifePo4 cells.
Here is the relevant screenshot:


I don't fully understand the points 1) and 2) above, but I don't want to be doing something silly.

Any thoughts or if you could explain a bit more I'd be extremely grateful.

The bond to dirt should be between the shunt and busbar.
If the bond were on the battery side of the shunt then you would be tracking spurious currents that are not going into or out of the battery.
The bond to dirt should also be between the bms and busbar so that the bond isn't is not disconnected when the BMS disconnects.

Point 1: If there was a short to a RV frame as an example, on a circuit, the circuit would still be complete as the ground point is between the BMS and the battery negative terminal. The fuse may not blow in all cases, as this is just a completed circuit. The BMS may be overloaded. Rare but possible.

Point 2: The circuit is still complete and depending on how it is switched, the circuit can remain active.
