ESS with 4th Multiplus on one Cerbo GX

Hi,
I have an ESS with three Multiplus 2 in a three-phase system. . To charge the battery using a generator, I bought a fourth Multiplus and already installed it.

I read somewhere that I just need to plug the fourth Multiplus into the VE bus. If I do that, the other three Multipluses immediately go into error mode and disconnect the ESS. They only start up again when I unplug the fourth Multiplus.

Is this not possible and do I need a second Cerbo GX? Or is it configured false? In that case, how to configure it correctly?

Thanks!

You can not connect it with ve bus, i have seen others using a usb mk3 cable to connect it to the cerbo, and seems to work for monitoring the multiplus

But it will stille be an unsupported configuration
