Is it possible to use 2 x multiplus2 5000 on a 3 phase connection. Ess is now running on 1 multiplus2 but i want to add a second one on phase 2. Now the multiplus2 is running on phase 1 and compensating for phase 2 and 3. i want to add one on phase 2,is that possible of can you only run 1 or 3 inverters? If it is possible and i connect both inverters on the cerbo do i need to configure the second inverter as a phase 2 inverter? Or just connect them and finish? The inverter is now only connected at the line in. Thank you in advanced! Richard ---

That’s possible, in VE.Bus System configurator you can select “dual phase 120” for this case. ---

Yes, I also wondered what that was for, but then one of my 3 multis died and I asked here and learned about it… ---

Oke, For me is it just for ess and keep 0 on the meter. 8kw in total is enough for 99% of the time. Maby in the future i wil go for a 3rd 5kva but for now it is ok. But then i want first more power from the solar panels (it is now 6kw) Battery power is already a little more then 90kwh so thats more then enough. It stays a build in progress 🤣🤣 ---

Do you have net metering and export limits? I have 2 phases and use 3 multiplus different batteries and sizes. I use 1 shelly 3em to monitor the grid. They are all running venus OS on rpi or cerbo. I have them set to manage all phases and not the invidual phase they are connected. It took a lot to setup but very impressive to watch them share the load and charge from excess PV grid connected solar. ---
