Hey all, Per Venus OS, v3.60 now in beta, more PV Inverters (SMA, SolarEdge, Enphase, Kostal and others) can be controlled by a GX device. Rather than just monitored/read-out. Until v3.60 this feature was only available for Fronius and ABB/Fimer. There are two features related to this active cont…

Answering myself to post a follow up question :wink: Is there still work going on to include Kostal in Modbus/Sunspec support? First of all, should this topic stay here, or may I use this info to create a feature request? I know there are a few hurdles but if I can do it, it should be a piece of …

Me too. Just like I tried to explain here Also: it looks like the “AC export current limit” set in “peak shaving” is not adhered to.

@TheRealStefan @Desperado I did put in a feature request quiet a while ago for two features regarding Modbus. You can find it here . I did add yours there. Perhaps we can upvote it together. :wink: Thanks and best regrads Christian

Enphase specifics Though confirmed by Enphase, in reality it is quite complex to make this working. Out of the box it doesn’t work, and help from Enphase Support desk is needed in order to enable the Modbus-TCP feature remotely. And getting that enabled has been reported by users to be quite diffi…

Tested with Sunny Boy 4.0 (Firmware version 4.03.07.R) and works fine.

[image] Gardenier BI: […] Once I finally managed to activate Modbus TCP, it worked fine. [..] @mpvader Are there any specific things I can test? Not really; just that the PV is limited, which you confirmed it is. Good that it works well!

If testers are needed in the future to specifically test with Enphase, I’m available! Location: near Rotterdam.

Thanks! No need though: With Enphase, it all works well. The only thing that you need to be prepared for as a user or installer is that it requires the Enphase support desk to make a change to your system.

To be precise, two changes: Activation of Modbus TCP Loading of the special Victron grid profile

Hello, I have started testing with Enphase and it seems to be working correctly. What I have observed, however, is that upon enabling dynamic power control, the solar production decreased to about 10W. This state lasted for about 10 minutes, after which it began to regulate production correctly. I a…
