SPK Modbus RTU Kit 1PH direct 803873267-ICU
This kit includes an direct external Modbus RTU energy meter, providing a cost-effective solution when there's no Dutch or Belgian smart meter available via the P1-port.
The energy meter can be connected to the RS485 port on all new Eve single products (NG910 V2 / NG910+).
This enables the seamless utilization of smart charging functionalities, such as Active Load Balancing, in countries outside the Netherlands and Belgium, eliminating the necessity to invest in an expensive Modbus TCP/IP energy meter.
See the smart charging implementation guide for more information.
Select the right Modbus-RTU-preset which is the "eastron sdm230”.
See the image below.Make sure that the address is set to the ID that is shown on the meter, update time is set to 2000, readout time is set to 500, and function code is set to Input register.
