Sungrow IDCxxx
The configuration process for the Sungrow charger is primarily managed remotely by Sungrow.
Configuration tip for Sungrow DC chargers
CLEMAP Load Management is fully compatible with Sungrow DC chargers and reliably controls their output power. Please note that CLEMAP regulates the power based on the AC measurement and does not take into account the internal AC/DC losses of the chargers.
- In dynamic circuits, this is not a problem: the system reacts in real time to the total consumption and automatically adjusts the charging power if necessary.
- In static circuits, however, the power loss cannot be captured. In the worst case, Sungrow chargers still reach 92 % efficiency.
To ensure safe and stable operation, we recommend allowing for a small safety margin in the configuration.
Example: With a 200 A fuse, this results in:
A safety margin of 16 A should therefore be configured in CLEMAP:
With this small adjustment, the system stays within the safe range even under high load.
Since the configuration is performed directly by Sungrow, you need to contact their support team. Proceed as follows:
- Send an email or open a support ticket with Sungrow.
- Provide important information
- Charger model and serial number
- Confirmation of your setup with CLEMAP Load Management
- Ask Sungrow to enable Modbus on the charger to allow communication with the CLEMAP system.
The gateway address 192.168.1.1 should preferably not be used in the router, as it is reserved internally by the charger. Choose a different gateway address instead, e.g. 192.168.2.1, to avoid conflicts.
Troubleshooting: No Modbus connection after a configuration change
Symptom After a configuration change by Sungrow (e.g. activation of Modbus), there is no Modbus connection to the charger.
Cause Modbus activation only takes effect after a complete and prolonged shutdown of the charger. A simple restart alone is usually not sufficient.
Solution
- Shut down the charger completely via OCPP.
- Then restart the charger.
Affected devices Sungrow chargers with Modbus integration.
