3. APPLICATION

EV Charging Stations

Three-phase energy meters can be used in compatible AC EV charging installations to measure electrical energy supplied to charging equipment. RS485 Modbus communication allows measured data to be collected by a compatible controller or monitoring system. For charging applications involving customer billing, confirm that the meter's certification and installation configuration meet the applicable requirements.

Solar PV Systems and Bidirectional Metering

In grid-connected solar installations, electricity may flow from the grid to the site and from the PV system back to the grid. A bidirectional energy meter can help distinguish imported and exported energy through the relevant measurement registers. Confirm the meter's supported registers and the overall system's metering architecture before selecting the model.

Commercial Buildings and Tenant Sub-Metering

Commercial buildings often require separate measurement for different distribution circuits, rental units or electrical loads. A DIN rail energy meter can provide local readings and, where supported, transmit data to a central monitoring system through RS485 Modbus. This helps facility operators organize electricity consumption data by circuit or metering point.

Industrial Energy Monitoring

In industrial distribution panels, energy meters can be used to monitor the consumption of compatible three-phase equipment, production areas or auxiliary systems. When integrated with a PLC or energy management platform, meter readings can support consumption analysis and operational reporting. Communication compatibility and the required measurement parameters should be confirmed during system design.

Energy Management Systems

For projects requiring centralized electricity monitoring, RS485 Modbus meters can be connected to compatible controllers or data acquisition equipment. Integrators should check the communication address, baud rate, register map, wiring topology and isolation requirements before commissioning.

FAQ

Has EM513082/83/84 meters obtained the mid certification?

Yes, all the EM513 series electric meters have obtained the MID certification .They are electricity meters designed to be used in the European market. EM513082/83/84 3-Phase MID Energy Meter with RS485 Modbus, 100A and Bidirectional Measurement

Can this meter measure both imported and exported electricity?

The product is specified for forward and reverse energy measurement. This capability can be useful in grid-connected solar PV and other bidirectional energy applications. Confirm the exact import/export registers and supported measurement modes for the intended configuration.

Can the meter connect directly to an energy management system?

The RS485 Modbus RTU interface supports integration with compatible systems. The host system must use compatible communication settings and register definitions. Additional hardware or software may be required depending on the system architecture.
