MultiPlus II Setup with PV -> Critical Loads

My Setup is as follows with 3 Multiplus II - 8000 for 400v 3Phase:

The PV Inverter is on the Net side then the Cable goes into the 3 Multiplus Input and then Output 2 goes into the house.

Now my question: In the VRM Portal it looks like this:

if i enable the switch AC-Output in ESS it looks like this:

vrm2.png


Why is critical loads in plus and so high when the Grid is negative? Why is load at 0? Is it because of the used Meter ET340? I read something about it giving wrong data in a single phase system?


Thanks!

Cheers

C.

Thanks. Could be. It says in that Menu: AC OUTPUT.

But if i enter the Menu, it says:

AC Input 1
AC Input 2
AC Output

But my Multiplus has:

Output 1
Output 2
Input 1

So, as shown in the picture im in the Input. So what could be the correct setting?

- Update

i just switched to Input 1 and now everything looks correct in VRM Portal. Wonder what happens if i switch to input 2 which is non existent on the multi.

That was it! Putting it to Input 2 (which i dont have in the Multi II) doesnt work. Input 1 works perfectly. Now all values are correct in VRM !! THANK YOU VERY MUCH !!!!!

The MultiPlus-II will use data from the external AC current sensor (must be ordered separately) or power meter to optimise selfconsumption and, if required, to prevent grid feed. In case of a power outage, the MultiPlus-II will continue to supply the critical loads. Monkey
