Huawei

The Teleport can connect to the residential and commercial scale Huawei Luna systems using Modbus TCP over ethernet or Modbus RTU over RS485.

The Teleport can also connect to a Huawei EMMA (SmartAssistant) to steer battery systems, using Modbus TCP over ethernet.

Setpoint operations

The asset can be controlled via the Teleport to set the following operations.

  • dispatchPower - to control active power setpoint

The command schema of the operating modes can be found in our API section, under SetBatteryOperation.

Modbus TCP over ethernet - configuration

  1. Connect an Ethernet cable between the asset and either a router or an Ethernet port of the Teleport. If connected via a router, please navigate to our appendix for more instructions on how to integrate with a router.

  2. Via the Huawei EMMA’s web interface, go to Communication settings > Router Configuration. Ensure DHCP is enabled.

  3. Go to Communication settings > Modbus TCP. Enable Connection.

  4. Go to Communication settings > Wired Network Settings. Ensure DHCP is enabled. Under the LAN section, you’ll have access to the device’s IP address. Provide this IP to Withthegrid.
