Works as expected on the SB5.0-1AV-41 !!

Thanks for this. Escalated to developer.

This is fixed in v3.70 beta and will likely be backed ported to v3.6x. Just noise, no functional change.
What I am missing is some documentation on how to connect an Enphase system to a Multiplus. (Or I missed it, please provide me the link).
Like this one I am looking for: AC-coupled PV with Fronius PV Inverters [Victron Energy]
The Enphase documentation is not complete to install/connect my Enphase solarsystem to the AC out 1 on my Multiplus II 5000. Modbus is activated bij Enphase support, so I do see it on VRM, Cerbo, Settings => Integrations => PV Inverters => Inverters.
For now my Enphase solarsystem is connected directly to the grid, I need some gidelines to connect it to the AC out 1 of the Multiplus.
Is Victron Enphase documentation available, like: âAC-coupled PV with Enphase PV Invertersâ?
After I know how to connect the Enphase to the Victron, I can provide feedback.

is there a whitepaper what to set on the other inverters.
The feature is really great and hopefully we can control all sunspec inverters
we tested with SE 17k fw0004.0023.0027 sunspec but didnât work . is there anything to set on the SE special
fronius has this checkbox to allow external CTRL
Hi Harmen, see link to Enphase documentation in the first post in this thread. Thats the best doc available now.

Hi Matthijs,
This Enphase document does not give me the confidence to connect my Enphase system to the AC out 1 Essential loads. Is Victron planning to provide a âAC-coupled PV with Enphase PV Invertersâ document?
In document AC Koppeling Enphase Victron of 2023 are some other schematics of Victron Enphase installations.
For now, I do not change the installation, the Enphase AC PV is grid connected. The 1:1 rule is applicable to my system. Not the 4,8kWh per 1,5kW AC PV lithium battery capacity.
What problem do you see in that document?
Victron supports the SunSpec protocol model 123 or 704 over Modbus and if the PV inverter also supports that it should work.
I donât think that Victron can or will provide detailed instructions for every available PV inverter.
Thanks! Not that important indeed, but anyway good to get rid of it, has been fixed and will land in a beta soon.
Any news - i think it would be great milestone if the list grow and grow of supported inverters:
Hopefully there is soon a whitepaper
Tested with a SMA Tripower20TL-30.
My Installer activated the external control (using a grid code from SMA) first, then we tested the grid feed-in reduction - which did NOT work at first.
The GX would send the new power values to the SMA (one could see that there were regular updates in the SMA log, for dynamic control settings changeing). However the SMA would not reduce the power/acknoledge the requested power output.
An inquiry with SMA revealed, that the Inverter (installed in 2020) needed an upgrade to the latest firmware - which we did.
After that, everthing works as expected.
SMA Firmware Version, that ist NOT working:
Firmware Version, that IS working fine:
Thanks & kudos to the Victron Team for the good work!
Edit: after updating the firmware, the SMA would no longer flood its log with the âdynamic control settingsâ, when the GX is actually changeing the Power setting. Looks like this behaviour is another sign, that a firmware update is needed.

Hello Matthias,
How can I find out which SE inverter is following SunSpec protocol model 123 or 704?
I have a SE9K FW 4.23.27, when writing a number between 1 and 99 to 0xf001 register the power is reduced to x% but only for 1 or 2 seconds, seams that there is something reseting my limit to 100%, any idea?
The SolarEdge supports (at least) two different power reduction methods. The GX enables Dynamic Power Control by initializing register 0xf300 to 1. In that mode, you need to keep writing the power limit to register 0xf322 before the configured timeout of 120 seconds expires. Only when the Dynamic Power Control is disabled, you can use the static limit using register 0xf001.

Many thanks,
just tested writing 0xf001 and it stays! Will test this tomorrow with sun.
but nevertheless I would like the get the Venus controlled limiter up and running before ELWG2025 will take a lot of money for feeding to grid 
Possibly I need to do some settings in the SetApp.
Again many thanks, appreciate your hints today and the next days.

It is also possible to keep using the dynamic power reduction, but to modify the Fall-back Active Power Limit in register 0xf312 (which is a 32-bit float instead of a 16-bit int for register 0xf001). That is the percentage to use when the GX is not actively reducing the power. I use that when the grid price is negative, since changing the power limit of the GX with node-red didnât work. Note that the change rate of the dynamic power control is much lower than the static power control: it can take up to a minute.
a few minutes before F1 start I would like to share may success controlling power of SE9K with node-red, V3.70~6 PWM slider, 0xf001 register and f300=0. 
No idea why the control via VenusOS doesnât work yet.
(Now I will keep my fingers crossed for Max)
My Enphase is running in a system with Cerbo, MP2-3kW and 10kW Pylontech on AC-out and I got modbus running, power shifting worked ! But after a few days the connection between Enphase and Venus disappeared, and Enphase gateway lost internet connection. The panels still produced power but are not vissible in Enlighten.
I could only connect with my Enpfase Metered in AP mode with the toolkit and managed to get it running again. The alarm log of ENphase was filled with faults âAC shut down activeâ âfrequenty out of rangeâ âdc to lowâ and in the end Envoy does not report.
Contacted Enphase to look at it but⌠no solution yet.
