VARTA Energy Storage

Installation

1. 1Connect the ModbusCloud gateway (MCG or MLP series) to the same local network as the VARTA energy storage system.
2. 2Ensure Modbus TCP is enabled on the VARTA storage unit and note its IP address and port (default Modbus TCP port is 502).
3. 3In the ModbusCloud platform, add a new device and import the VARTA Energy Storage template from the template library.
4. 4Enter the IP address of the VARTA unit and confirm the Modbus TCP port in the gateway configuration.
5. 5Verify that the firmware version on the VARTA system matches the register map used in this template, as addresses may differ between versions.
6. 6Check the live data view in ModbusCloud to confirm that SOC, active power, and grid power values are updating correctly.
