I've decided to try the plugin in a different inverter of a friend of mine: model X3-Hybrid 10-E-D but there are connectivity issues. The debug log is

I've then tried to ping the inverter (all fine) and check if port 502 was open using nmap

$ nmap -p 502 192.168.88.21
Starting Nmap 7.80 ( https://nmap.org ) at 2024-07-18 18:43 BST
Nmap scan report for 192.168.88.21
Host is up (0.0057s latency).

PORT    STATE  SERVICE
502/tcp closed mbap

Nmap done: 1 IP address (1 host up) scanned in 0.16 seconds

So it seems that it is closed for some reason :-(. I've roamed the internet but found no reason why this would be. Does anyone have any suggestions/things to try? Thanks.
