Looking for a solution to implement a Kostal 3Phase Inverter via ModbusTCP to a Venus GX.
What I came up with:
I already have a different Installation running Sunspec for a Solaredge --> Setting Device ID126 and getting that Inverter Connected to my GX device (running almost a year)
With a new installation I have a Kostal, that has ModbusTCP implemented, but not working on a GX Device..
- Basically I enabled Modbus TCP on the Inverter
- I redirected the not changeable Modbusport 1502 to 502 via an external rerouting
- I Changed the device ID from 71 to 126 (as well to quircks the GX)
- (I checked all Sunspec Register with an external Software I wrote and get all infos)
But now things are different
On SolarEdge ModbusTCP Registerlist starts at 40070 with all necessary data
on Kostal ist starts on 40071
So the GX Device does not understand what s going on because of that one Address Shift
Has anybody connected a PV Inverter with different PORT and a different Initial ModbusTCP Register Starting Address?
Or from the other side:
Is it possible to change the Settings in the VE device via SSH, or do I have to Implement an external device or write my own internal Codeblock to get things running.
Answers highly appreciated
