Victron Quattro Microgrid control via Modbus TCP

Q&A and troubleshooting

Hello,

We have a battery pack with a total of 6 15kVA Quattros (and a cerbo gx), that generate a three phase supply. Today i wanted to check the new Microgrid functions by controlling the inverters via Modbus but could I not write or read anything on the necessary registers.

Registers 200 to 231 were met with an “illegal data adress”

Register 109 “UPS Function” works fine.

Is there something I am missing or is this just not yet implemented since this is a newly added functionality?

Microgrid is not controllable by modbus. It is a dedicated configuration that must be configured with veconfigure and special firmware. The units control each other via frequency and voltage shifting.
It requires multiple, independent victron systems connected together via AC IN.
The manual is very thorough about the setup and requirements.
