1x Multi RS Solar 6000 zero feed-in on 3-Phase ESS not working

[Raphael_Hofmann]

Hi, I have a 3-Phase Grid and only a single Multi RS Solar 6000 on phase 1 installed.
I use the VM-3P75CT Energy Meter, set to 3-Phase, CAN-connection.
I do not want to feed-in Excess solar in this installation.
With a MulitPlus-II it is possible to set Multiphase Regulation in the Cerbo ESS settings.
And disable DC-Solar Feedin.
This is not possible with the Multi RS jet.
If I set the Maximum feed-in limit to 0W, it only applies to Phase 1:

It does not compensate for the consumptioin of L2 and L3.

Multi-Phase regulation works just fine, without limiting the System feed-in:

But once the Battery is fully charged, excess solar is feed back to the grid.

Maybe you are waiting on some updates. I had my Multplus 2 installed on phase 2. It thinks it’s one phase 1. My installer did this to spoof it and allows me to do some cool stuff with Node-Red. Maybe switch the CT and see what happens.

Also, have a look and see if there is a Node Red node for the unit and what input and outputs you can use. There are also some yellow nodes with features that are not available to test.

i wrote to my contact at victron and ask for some advice there. Because of summer holidays it will take some time.

How is the VM-3P75CT connected to the system? VE.Can or Ethernet?

Currently only the connection via VE.Can is fully supported with the Multi RS.

The Ethernet connection is currently in beta testing.

CAN connection. The function is just not implemented jet…

Matthias, any way to signup for beta testing?

[M_Lange (Matthias Lange - DE)]

It’s an internal closed beta.

Hi Matthias, after installing 1.26 on the MRS VM-3P75CT lan support seems to be working but is not mentioned in the release notes.. could you maybe tell more?

[M_Lange (Matthias Lange - DE)]

For the full support there is still a Venus OS update needed (currently in beta), after that update is available there will be a public announcement.

Thanks for the information, do you know if there is a plan to support other electric meter over GX device?

[M_Lange (Matthias Lange - DE)]

In the Venus OS 3.70 beta Victron is testing support for Shelly products.

Venus OS beta testing

Victron already supports a few energy meters, what are you missing?

But not with multi RS together. The LAN implementation is only for the victron owen one. Or do I got something wrong?
