Hello,
I have a Greenheiss inverter, this is the manual pdf (I only could find it in spanish sorry).
I would like to integrate it into Home Assistant although there is no addon to directly integrate it.
I’ve been investigating and here they say I could use the GoodWe inverter integration, although I’m getting an error "Unknown error occurred"
with this showing in the logs:

Somewhere else I also found that those inverters could be possible to integrate it with SAJ solar inverter integration.
this is what I’ve added into my configuation.yaml
sensor:
- platform: saj
host: 192.168.18.45
type: wifi
but it is not connecting to the inverter, and this is what the log is showing for this integration
2025-04-02 17:57:41.397 WARNING (MainThread) [pysaj] Connection to SAJ inverter is not possible. The inverter may be offline due to darkness. Otherwise check host/ip address.
Any help would be really appreciated.
Thanks.
