BMV and multiple Venus GX units

Is it possible to connect a BMV battery monitor to multiple Venus GX units using a USB hub so that they all see the same battery SOC?

Hi Mark, this is not possible unfortunately.

What do you want to accomplish? multiple systems on one battery bank?

Pity - I am running a 3 x single phase system each with own mppt, multiplus and Venus connected to a single battery bank. I was hoping to use the Bmv to give accurate soc info to the inverters - how can I achieve this?

I'm afraid the only thing that would work is to use multiple BMV's

thanks Daniel - so you propose 3 BMW units connected to a single shunt?

That is possible, but not officially supported.

It should work if the connections are done well.
