How its expected to work I expect the system to start feeding in to grid when the battery is full and there is more PV available then the loads are asking for. How it doesn’t work as expected The system does feed in to grid from battery, and from Solar also normally. But when DESS has set the…

Hi, My site: VRM Portal - Victron Energy A few weeks ago the Multi RS’S stopped feeding in to the grid after a firmware update. At that time I did not know I had to re-enter the grid code after every firmware update. After re-entering the grid code the system started to feed back in. And it is s…

Hi, I’ve exactly the same problem. So if you need more sites for checking, don’t hesitate to contact me.

Hello from Germany! I noticed exactly the same thing on my system last weekend… 1x 1 phase MP2 48/5000 2x SmartSolar 250/85 (connected via CAN) 1x 500A Smartshunt 2x self-built batteries, each with a JK Inverter BMS, also connected via CAN. Firmware on the Cerbo, whether latest stable or 3.60~66…

This isn’t about Multiplus inverter/chargers, this is about the newer Multi RS 6000

However, the error seems to occur across all devices and is not limited to a specific device series. This will help everyone if the cause is found…

None of what you are describing has anything to do with this topic… I think you’re commenting on the wrong topic, this topic is about Multi RS grid feed in, not about DVCC.

I may have expressed myself unclearly, but I also had EXACTLY the problem described in the initial post and at the SAME TIME I also had the problem with the DVCC settings. Both out of nowhere, without changing anything in the system. Sometimes it’s details like this that lead a developer to the root…

But it IS relevant that this topic is about the Multi RS only, because the whole software is different compared to MP2, for instance the Multi RS only communicates via VE CAN and Victron connect, not VE Bus and VE Configure. The entire ESS settings are completely different on Multi RS and the firmwa…

Hi Dognose, i have the same issue as AukedeGr, my system with 3 Multi RS Solar 48/6000 stops also supplying energy to the grid when there is full sun, the battery is full and positive energy prices. When disabling DESS, the system proceeds supplying energy to the grid. Thanks, Danny

We are currently investigating this issue, it only seems to affect the MultiRS when running with DESS. What @towatai described with the unavailable DVCC settings for MPs is more or less unrelated to the MultiRS, even if the symptoms may look the same.

I have the same problem.
There is a also a thread in the German section of this community discussing the problem:
