GoodWe HCA Wallbox (Gen2)

← Chargers

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.

Supported features

• mA regulation: Finer charging current regulation (mA instead of A) for better solar surplus use.
• RFID: Integrated RFID card reader for vehicle identification.
• 1P/3P: Automatic phase switching. Useful for solar surplus charging.
• Built-in meter: Support for an integrated meter.
