Modbus is designed to mostly have a single Master. If you try to connect multiple instances to the Inverter ie this Integration and Node-RED the Inverter will either block the second connection or likely to result in data collisions.

If this happens it's recommended to use a multiplexer such as https://github.com/IngmarStein/tcp-multiplexer this has been tested by reading and writing from two instances of HA at once.

This can be started with Docker or Docker Compose. Example Compose:

services:
 modbus-proxy:
 image: ghcr.io/ingmarstein/tcp-multiplexer
 container_name: modbus_proxy
 ports:
 - "5020:5020"
 command: [ "server", "-t", "192.168.123.123:502", "-l", "5020", "-p", "modbus", "-v" ]
 restart: unless-stopped

Server address is the Inverter / data logger. You then direct this integration to the machine running the proxy and port 5020 in this example.
