Hello everyone!
I have just installed a microgrid system, composed of the following devices:
Fronius Primo 5kWh, Victron MP2 5000, CerboGX, ET112 and a Pylontech US5000 battery. My problem is that I cannot stop the injection of excess energy into the grid, although this option is disabled in the ESS menu.
I specifically say that in the Fronius administration panel the control priority first option is set to Modbus, and if I also limit the surplus injection to 0, then the system only produces somewhere around 40-50wh.
On the same topic, I still have a similar system installed at my brother’s home and I have the same problem. Am I wrong somewhere?!
Does anyone know if this option is also dependent on other settings or do you have a solution for this?
Have you followed the instructions in the docs for zero feed in?
In “AC coupled” system it should not be limited. Victron does the export limitation through the ESS assistant, but unfortunately, this time it does not execute and I can’t figure out why…
It should be discovered by the GX which will use modbus to control the inverter.
I know. The Modbus is setup at first priority, but if I set Limitation on Fronius to 0 export feed-in, the solar production of the system is only around 40 W…
Perhaps share a detailed configuration of your inverters, GX etc.
The system is described above. What more could I detail?! On the same topic, I still have a similar system installed at my brother’s and I have the same problem. Am I wrong somewhere?!
If you want someone to provide guidance you will need to detail your settings and configuration. Otherwise it is just guessing.
There is way too little information to even start to help.
It sounds like either missing or incorrect configuration.
