Cannot get my 3-phase multirs to charge / discharge my battery

I have:

  • 3x Multi RS 6000
  • Cerbo GX MK2 ( with touch screen)
  • VM-3P75CT
  • 3x EEL Battery box V5 (JK BMS V19 v4.28.0)

MultiRS via CAN port 2 daisy chained to the cerbo, terminated, and from the other port to the VM meter, also terminated.

Then on the CAN port 1 (BMS) I have an A-B cable connected to my JK BMS o nteh CAN Bus,

All seems to be working, I see the actual grid measurements, the current voltage, state of charge, everything.

However I cannot get my MultiRS to charge or use the battery. A am still in the process of adding solar panels, but I recon at night the system should be able to keep my meter at 0?

I am a bit at a loss, are there any known bugs or issues, this is my first system, first time I am trying to get it working. I checked everything multiple times.

If somebody please could give me some advice or a hint… I have my JK BMS set to the settings recommended by the “Solar Garage” for lipofe4.

Thanks in advance

Hi Jelle,

It definitely sounds like a configuration issue.
To help troubleshoot, could you explain how you have configured the three Multi RS units? With three inverters, the typical and supported setup would be for a 3-phase system.
It would be worth confirming if you have connected to each inverter individually with VictronConnect and assigned each one a unique phase (one as L1, one as L2, and the third as L3).
Maybe you can include some screenshots or pictures of the configuration?

I configured it as a 3 phase system, L1, L2, L3.

i set the meter to 3 phase also, and set role to gridmeter.

When I get home tonight I can post some screenshots.

What are your settings in ve configure?

So all batteries appear in the victron remote console without errors?

Depends on settings, have you set up ESS? Are you using DVCC? I think default behaviour is keep batteries charged, only use battery power on grid outage.

On the mobile app i was able to take some screenshots. I did this for the meter and L1.

I see the battery, it also has an expected charge and discharge current.

In the third screenshot ESS is set to keep batteries charged. This prevents discharging except on grid outage, see manual.

You can set the minimum SOC to 80% to test charging from the grid.

I already tried that, no change. I tried everything, grid setpoint does also not seem to apply. I think I have tried all modes, even pulling ac-in did not cause it to use the battery.

I just noticed this post

Setting it to 1… happy days…

Thanks for your help… after 4 days of pulling my hair out it seems to work. I will test some more

Glad its solved, bit of a unclear setting indeed
