IVY Metering Introduces the EM619025–27 Series: Smart Bi-directional DC Energy Meters for EV Charging, Energy Storage and Renewable Energy Applications

IVY Metering, a professional manufacturer of smart energy metering solutions, proudly announces the launch of the EM619025–27 Series Smart DC Energy Meters, a new generation of high-performance direct-connected DC meters designed for electric vehicle charging, battery energy storage systems (BESS), photovoltaic installations, and other high-voltage DC applications.

As global electrification continues to accelerate, the demand for accurate, reliable, and regulation-compliant DC energy measurement is growing rapidly. The EM619025–27 Series has been developed to help equipment manufacturers, charging infrastructure providers, and system integrators achieve precise DC energy monitoring while supporting future regulatory requirements in international markets.

Engineered for Modern DC Metering

The EM619025–27 Series combines compact DIN-rail installation with an integrated shunt design, making installation simpler while reducing wiring complexity. Supporting direct current measurement up to 1000V DC and current ratings of 200A, 400A, and 650A, the series is suitable for a wide range of medium- and high-power DC systems.

Designed specifically for demanding applications, the meters provide:

• Bidirectional energy measurement

• Class 1 active energy accuracy

• Voltage range from 100V to 1000V DC

• Direct-connected current measurement up to 650A

• Compact 3.5-module DIN rail design

• Real-time LCD display with automatic page scrolling

These capabilities make the series ideal for applications where accurate energy monitoring and reliable long-term operation are essential.

Built for EV Charging and Smart Energy Infrastructure

The rapid deployment of DC fast chargers requires energy meters that deliver not only measurement accuracy but also secure communication and flexible integration.

The EM619025–27 Series supports both RS485 and Ethernet communication, enabling seamless integration with charging controllers, energy management systems (EMS), SCADA platforms, and cloud monitoring systems.

Compatible communication protocols include:

• Modbus RTU

• DLT645-2007

• HTTP JSON

• HTTP OCMF

The meters also generate S.A.F.E.-compliant OCMF readings, supporting transparent energy transaction records for public charging infrastructure.

Designed with Intelligent Functions

Beyond energy measurement, the EM619025–27 Series incorporates a wide range of intelligent monitoring and protection functions that improve operational reliability.

Key intelligent features include:

• Line loss energy compensation

• Built-in self-diagnosis

• Overcurrent detection

• Overtemperature monitoring

• Magnetic field detection

• Low battery warning

• Local and remote firmware upgrades

• Automatic network time synchronization

• Real-time shunt temperature monitoring

These functions help operators identify abnormal conditions early, reduce maintenance costs, and improve system availability.

Ready for International Compliance

As regulations for DC energy metering continue to evolve, manufacturers increasingly require products that are prepared for global certification.

The EM619025–27 Series is designed to satisfy multiple international standards and regulatory requirements, including:

• IEC 62052-11

• IEC 62052-31

• IEC 62053-41

• GB/T 33708

• JJF 1779

The platform is also designed to support MID, PTB, CPA, and German Eichrecht certification requirements, making it an ideal choice for international EV charging projects and regulated DC metering applications.

Supporting the Next Generation of DC Power Systems

The expansion of electric mobility, renewable energy, and battery storage continues to drive demand for smarter DC energy measurement solutions. From ultra-fast EV charging stations to photovoltaic systems and industrial DC distribution networks, accurate metering has become a critical component of efficient energy management.

The EM619025–27 Series has been developed to address these evolving challenges by combining measurement accuracy, intelligent diagnostics, flexible communication, and future-ready compliance into one compact platform.

Whether deployed in EV charging infrastructure, energy storage systems, solar power installations, or DC microgrids, the new series provides equipment manufacturers and system integrators with a dependable solution for modern DC energy measurement.
