Monitoring and measurement solution for Battery Energy Storage

Basic requirements

• Continuous monitoring of the point of delivery with a measurement interval of 200 ms.

• Measurement of individual loads: power (P, Q, S), frequency, and other values.

• Communication via RS485 (Modbus RTU) and Ethernet (OPC UA, Modbus TCP).

Example of measurement and data collection solution

• Measurement of electrical and non-electrical quantities (heat, water, gas) connected to EnMS.

• Centralized data collection, trend analysis, and consumption evaluation.

• Compact integration using ProData2 and Janitza UMG series meters.

System planning and design

• Identification of key measurement points and monitored parameters.

• Architecture design – combination of Ethernet, RS485, and M-Bus according to application needs.

• Selection of suitable meters with respect to required accuracy, interfaces, and installation.

• Ensuring automatic time synchronization (NTP).
