# GoodWe HCA Wallbox (Gen2)

Bron: https://docs.evcc.io/nl/chargers/goodwe-hca-wallbox-gen2

Enable Modbus TCP in the SolarGo app via "Communication → Wallbox".
Default device ID is 247 (0xF7).
The wallbox only accepts 2 concurrent Modbus TCP sessions (1× SEMS cloud, 1× client). If the cloud is active, evcc competes for the second slot.
Note: Implementation is derived from the Home Assistant integration (gen2-modbus branch) and is not vendor-verified.

Ondersteunde functies: mA, rfid, 1p3p, meter

Sponsortoken vereist: dit apparaat is beschikbaar voor sponsors van het project, zie https://docs.evcc.io/nl/sponsorship.
