Maybe @mvader (Victron Energy) knows the answer on this one?

Hi, I don't know what is wanted to be queried here. And the query seems to query 434 addresses at once?

I'd start with single register queries, and make sure to super closely read the explanation about register numbers and unit ids in the Modbus TCP documentation:

Hope that helps!
