Connecting multiplus 12/1600/70 compact to BMV 712-smart and Victron connect

Dear users,

Again a question from me, I think I settled for the following setup:

- Multiplus 12/1600/70 with temperature sensor for battery

- BMV-712 smart with bluetooth

- 75 - 15 MPPT with bluetooth (300W solar panels)

- Orion TR DC-DC 12-12/30 with bluetooth

- 200ah lithium battery with 200A BMS (not from victron)

My question: What is the best way to connect my multiplus to the victron connect app? I read multiple options. And what is the cheapest and which one is the best for me? Bluetooth dongle, or GX and which one then?

I am going to use my multiplus for charging and for my 1000W airfryer, most of the time it will be used once a day for 15 minutes. Am I using the right setup then? (extra question: Does the multiplus need a lot of free space for cooling?)

Kind regards,

goon326

Best is to get a Cerbo, probably the S model. This offers integrated control of charging and remote monitoring configuration. Connect all units to the Cerbo with the right cables.

Use Victron Connect with Bluetooth to configure devices as well as monitor performance.

And how do I connect my MPPT and BMV to the Cerbo? Does this goes via bluetooth or via a cable? And do I need a GX Touch with the Cerbo? Or can I see the information that is on the screen also in the victron connect app?

Use cables if you can, usually VE Direct.

Screen optional, all settings/reports are available via the app.

Does anybody know if the 35mm2 cables that are connected to the Multiplus 12/1600/70 are enough to use the full capacity of the DC/AC converter? Or should I connect 50mm2 cables?
