MPPT multiple setup

Hello, I need some advise. On my boat I have two sets of Victron panels 1x90W and 2x115W (I had to take different once as there is no space for 3x115W and there for there are two MPPT to draw max from the panels). They will be run by two MPPT. To monitor state of the batteries I installed BMV-700 unit. The MPPT are in the network and I found information that I would need smart shunt to connect to the network in order to "inform" the mppt about the voltage and current of the battery. The BMV 700 does not have bluetooth so I thought about getting the VE.direct to Bluetooth Smart dongle and connect it to the BVM.

Will this work?

Below I posted picture of the setup and the diagram sketch - could you please comment the setup :)

The Smart Charger I am using when I am in port and there is access to the electricity.

The BMV with the dongle transmits voltage and current sense. I dont know how old yours is but check its not out of range in the link.

You have fused your panels - excellent. Just note that opening fuses for pv under load (while producing) is not recommended.

Have you fused the mppts to the bus bar? Check their manuals that is a recommendation there.

Thank you for a quick response! I don't have any additional fuses. Do you mean bus bar as such:
