Connecting victron 75/15 to existing fuse hub

Currently we have 640w of solar going to an mppt controller, in parallel, which goes to a 200ah lithium battery via a fuse hub.

Have just added 2 x 100w solar in parallel using victron 75/15 smart controller directly to battery.

We a drifter monitor which reads battery soc and amps etc of original 640w but does not include victron input. We think this is because its all linked to the fuse hub.

Our question is if we run the positive battery cable from controller to the fuse hub, can the negative be left directly on battery, or, does it need to go to fuse hub as well ?

Hopefully we can then get readout of combined input.

Any help appreciated

If the negative is connected directly to the battery then it is most likely bypassing the shunt of the Drifter battery monitor and so the energy from the 75/15 will not be counted.

It's be better to connect the battery negative from the 75/15 to the fuse hub negative.
