Configuration and Interface Details
The Kempower Charging Station uses Modbus TCP as the communication basis.
To ensure communication with the SmartgridOne Controller, note the following:
- Connection Requirements: Connections are only allowed from the same subnet the charging station is connected to.
- Modbus Port: The standard Modbus Port used is 502.
- Maximum Connections: The maximum number of simultaneous connections is 10.
Power Limit Management
The Kempower Charging Station accepts power limit control only via the Modbus TCP interface when Modbus messages are detected.
- OCPP Conflict: OCPP power limitation messages are not accepted when Modbus is used.
- Fallback Power: The maximum power used when communication times out reverts to the Fallback Power (W) setting. This power is also used at startup until the Assigned Maximum Power has been received.
- Minimum Power: Any power limit values below 1000W are interpreted as 0W, which effectively stops charging.
