I wanted to share my experience integrating the Goodwe GW10K-BT inverter with Home Assistant. Initially, I faced some challenges with the battery management system (BMS) disabling the charging function, which was quite frustrating. However, after some research and troubleshooting, I managed to resolve the issue by adjusting the settings and ensuring proper communication between the inverter and the Home Assistant ecosystem.
Here’s a quick overview of what I did:
-
Understanding the Problem: The BMS was disabling charging at around 94%, which I later found out was due to the power factor (PF) settings. The inverter was prioritizing grid export over battery charging.
-
Adjusting Settings: I modified the PF settings in the Goodwe app to give higher priority to battery charging. This involved tweaking the self-consumption settings and ensuring that the inverter communicated correctly with the Home Assistant through MQTT.
-
Integration with Home Assistant: I used the
goodweintegration in Home Assistant to monitor and control the inverter. This allowed me to set up custom automations, such as adjusting the charging schedule based on solar production and grid availability. -
Testing and Validation: After making the changes, I monitored the system closely. The inverter now charges the battery to 100% without issues, and the excess energy is exported to the grid only when necessary.
This experience taught me the importance of understanding the underlying settings and how different components interact within a smart home setup. I’m now confident in managing my energy consumption more efficiently.
If anyone else is struggling with similar issues, I’d be happy to share more details or tips!
