Grid und Batterie erfordern den PowerSensor.
"Modbus/TCP" erfordert Freischaltung via "Errichterzugang" in den Kommunikationseinstellungen des Wechselrichters.
Siehe https://forum.huawei.com/enterprise/en/modbus-tcp-guide/thread/667250677153415168-667213868771979264
Netz und Batterie erfordern den Huawei Smart Power Sensor (DDSU/DTSU666 or SmartPS).
Modbus TCP erfordert die Freischaltung in den Kommunikationseinstellungen des Wechselrichters via "Installateur Zugang", siehe [Modbus TCP Aktivierungs-Anleitung](https://forum.huawei.com/enterprise/en/modbus-tcp-guide/thread/667250677153415168-667213868771979264).
##### WARNUNG!
Die folgendenden Gegebenheiten können zu Unterbrechungen in der Modbus-Kommunikation führen:
- veraltete Firmware
- Änderung von Wechselrichter/Speicher-Einstellungen über das Huawei FusionSolar-Portal
- weitere Anwendungen (z.B. Home Assistant) greifen über einen Modbus Proxy auf die Anlage zu (auch abhängig von der Anlagenkomplexität, z.B. Anzahl kaskadierter Wechselrichter)

Grid and Battery require the PowerSensor.
Modbus/TCP requires activation using "maintenance access" within the communication settings of the inverter.

Grid and Battery require the Huawei Smart Power Sensor (DDSU/DTSU666 or SmartPS).
Modbus TCP requires activation within the communication settings of the inverter using an "installer account", see [Modbus TCP Activation Guide](https://forum.huawei.com/enterprise/en/modbus-tcp-guide/thread/667250677153415168-667213868771979264).
##### WARNING!
Please beware that the following circumstances may lead to Modbus communication interruptions:
- outdated firmware
- altering inverter/battery configuration settings via Huawei FusionSolar portal
- other applications (e.g. Home Assistant) accessing the inverter via Modbus proxy (also depending on plant complexity, e.g. number of cascaded inverters)
