Support for Goodwe solar inverters is present as native integration of Home Assistant since its release 2022.2 and is recommended for most users.
This custom component is experimental version with features not (yet) present in standard HA's integration and is intended for users with specific needs and early adopters of new features. Use at own risk.
- Support for Modbus/TCP
- Special work modes
Eco charge modeandEco discharge mode(24/7 with defined power and SoC). - Network configuration parameters
Scan iterval,Network retry attempts,Network request timeout. - Switch
Export Limit Switch. - Switch
Load Control(for ET+ inverters). - Services for getting/setting inverter configuration parameters
If you have been using this custom component and want to migrate to standard HA integration, the migration is straightforward. Just remove the integration from HACS (press Ignore and force uninstall despite the warning the integration is still configured). Afrer restart of Home Assistant, the standard Goodwe integration will start and all your existing settings, entity names, history and statistics should be preserved.
(If you uninstall the integration first, then uninstall HACS component and install integration back again, it will also work, but you will probably loose some history and settings since HA integration uses slightly different default entity names.)
The integration provides several values suitable for the energy dashboard introduced to HA in v2021.8.
The best supported are the inverters of ET/EH families, where the sensors meter_e_total_exp, meter_e_total_imp, e_total, e_bat_charge_total and e_bat_discharge_total are the most suitable for the dashboard measurements and statistics.
For the other inverter families, if such sensors are not directly available from the inverter, they can be calculated, see paragraph below.
The sensor values reported by the inverter are instant measurements. To report summary (energy) values like daily/monthly sell or buy (in kWh), these values have to be aggregated over time.
Riemann Sum integration can be used to convert these instant (W) values into cumulative values (Wh). Utility Meter can report these values as human readable statistical values. Template Sensor can be used to separate buy and sell values.

goodwe: debugThe source code implementing the actual communication with GoodWe inverters (which was originally part of this plugin) was extracted and moved to standalone PyPI library. This repository now contains only the HomeAssistant specific code.
To test whether the inverter properly responds to UDP request, just execute the inverter_test.py script in your python (3.8+) environment.
The inverter_scan.py script can be used to discover inverter(s) on your local network.
