Modbus connection not stable

[joelegg]

Describe the bug

not sure if this is something that can be fixed on this side, but solaedges latest firmware has had issues with modbus connection staying stable. firmware 4.24.14

The conneciton connects (reload) then fails/drops after 5 seconds or so after that.

Failed setup, will retry: Setup failed: Modbus Error: [Input/Output] No response received after 3 retries, continue with next request

It seems to connect sometimes not others.

Expected behavior

stable connection

maybe this is because you have another solaredge plugin installed?
"https://github.com/binsentsu/home-assistant-solaredge-modbus"
just an idea...

could be! its instaled but not setup. i have just deleted it.

I have the same issue, and I have verified that no other solaredge integration is installed.

I am also scanning the ports of the inverter... and I can't find or detect anything. The modbus should be in the tcp 1502, is it possible that SolarEdge has disabled the function?

[joelegg]

Yes. You need to connect to your inverter and enable it.
