To fix the issue, I checked the SSL/TLS option on all HTTP requests.
Add a new config if one doesn't exist, and uncheck 'Verify server certificate' and Update.
Redeploy the node and that should fix the issue.

Hi @Ivan_E
I'm in the UK and I think my SunSynk 5.5kW inverter is the same one as yours. See pic below:
I'm looking to set up a similar ESP32 set up like yours. I was wondering how you have it set up. How are you powering the ESP32 board?
If you have a link of which ESP32 board you bought plus modules would be a great help.
Many Thanks
