## Huawei FusionSolar
In order to communicate with the Huawei FusionSolar inverter, a working communikation must be provided. This can be done with a Huawei SmartDongle or with a direct modbus RTU connection.

* Huawei Meter (connected internally to the Inverter)
* Luna2000 battery units 1 and 2 if connected
The batteries will be shown in the system as informative things, but will not be considered in the energy view and and energy balance. Since the batteries are connected internally behind the inverter, power coming from the battery will be shown as power coming from the inverter. The inverter power represents power from the PV or from the battery.
### Huawei SmartDongle
The [SmartDongle](https://solar.huawei.com/-/media/Solar/attachment/pdf/apac/datasheet/SmartDongle-WLAN-FE.pdf) can be used to communicate
