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…

Tested on: Solaredge SE7K Firmware 0004.0020.0036 Venus OS V3.63 ‘Dynamic power limiting’ can (sometimes) be enabled on the Cerbo, but the connection between the Cerbo and the Solaredge is completely unstable. Sometimes the connection is disconnected for several hours and then spontaneously reco…

I control my 3 Growatt Inverters via nodered, mqtt and Tasmota modbus bridge. I read out al 3 of them and Nodered puts this data in the victron pv nodes which works flawless. Is there a node for nodered that outputs the current wanted solar percentage which I can write to my Growatt Inverters?

It works perfectly for Kaco blueplanet NX3M2 Inverters.

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 …

@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!

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.
