MPPT Ground to chassis or common bus bar

This question is regarding the Victron 100/50 MPPT Smart Solar Charger for a van conversion installation.

The entire electrical system is grounded to the van chassis. Specifically, I have a wire bolted to the van and then connected to the main negative bus bar.

I have the negative wire of the MPPT Smart Solar Charger connected to the main negative bus bar, and the positive wire of the MPPT Smart Solar Charger connected to the main positive bus bar.

Can the ground wire of the MPPT Smart Solar Charger also be connected to the negative bus bar or should it be connected to the van chassis?

I would prefer that the ground wire not be connected to the van chassis, but rather connected to the negative bus bar, along with all the other negative wires.

Hoping to get some more clarification on this.

thanks
