Can I use ABB UNO-DM and Pylontech at CCGX?

My system: ESS with Multi-II by VE.Bus on CCGX (current firmware), Pylontech US2000B by VE.Can on CCGX, EM24 by USB on CCGX. My almost 20 years old PV-Inverter is displayed on CCGX by the Victron Current sensor.

I will in future reduce grid feed-in to zero.

For my system it is the best, when I can use one ABB UNO-DN-2.0 TL-Plus-B-Q on Output1 of the Multi-II. Herefore it is needed that the PV-Inverter is be regulated. When I use the ABB UNO DM-COM Kit, it use RS485/Modbus. But it is not possible to use the VE.Can on CCGX, because of the Pylontech.

What is the best way for connecting ABB UNO PV-Inverter on the CCGX? Is ist able to use the second VE.Bus-Connector or the Ethernet-Connector. I will don´t use a wireless-system because of the radiation.

Supplement to my question:

Is it possible to use the free second USB-Port with a FTDI USB-RS485-Adaptorcable (the same which I use for the EM24)?

Hi,

This is unfortunately not possible as long as your PV inverter does not properly respond to frequency shift.
The regulation can only happen via this method.
