3x Multi RS Solar throttling feed in, why?

[vaursechs (Nick Ebben)]

The Multi RS has much better cooling compared to the MP2, I had 3x MP5000 before I switched to the Multi’s, the MP2 were getting HOT compared to the Multi RS. In fact, the metal case of the Multi RS isn’t even getting warm at all.

However, even if the Multi would get 60C, this still is not an answer to “why” in the title of this topic, as the feed in limit is FIXED to 5kW, no matter what, even if the Multi is only delivering 100W and my AC coupled PV inverter is doing 4900W, the total amount CANNOT exceed 5000W, UNLESS the external current sensor is disabled, then I am able to get over 10.000W.

As Matthijs Vader said, they are working on a fix for the 5kW feed in limit.

It seems the problem is fixed for today at my system:

What did I do? I had switched my AC inverters and the load completely to AC OUT. 20A Limit was there. Now I have switched both back to AC IN (as it was before with the 20A feed-in limitation) but now there is no longer this limitation. I am curious whether this is now permanently the case

The only thing i see is that the power of the mppt drops for 30min when the bat is full:

.

The only thing a changed is a node red flow that limits the bat charge current, so that the battery will not be fully charged in the morning hours but in the peak hours…

[vaursechs (Nick Ebben)]

But do you mean you have PV and LOAD both on AC-in?
I cannot put my loads on AC-in as I would lose the backup feature during grid loss.

Also, do you have the setting “Energy Meter support” enabled?:

[vaursechs (Nick Ebben)]

I believe that your grid fuses are a lot higher than 3x 35A, which is why you don’t need the external current meter support turned on in Victron Connect. But since my fuses are 3x25A, I cannot disable that function, so I am still limited to 5000W export per phase

[mode]

Since i do not need to throttle AC IN at all i wrote this node to fix the problem:

When the feed in current is more then 20A then the External Meter in Multi solar is switchted of. When its below 15A it is switches back on.
When you have your AC Inveters on AC IN this works and you will not run into throttling issues again till the new firmware is released.
