Communication Solution Between Energy Storage Equipment and Energy Management Platform (Modbus to IEC104)

Published: 2026-05-20 11:16:05

At the energy storage power station site, multiple types of equipment are deployed, including battery management systems (BMS), power conversion systems (PCS), temperature control units, and fire safety systems. Most of these devices use the Modbus RTU/TCP protocol for data exchange. However, due to the wide variety of brands and models and the lack of a unified communication protocol, these devices have become isolated data silos.

 

Since the equipment typically operates independently, management staff are unable to perform centralized monitoring. Manual onsite inspections are timeconsuming and laborintensive. Key parameters such as battery voltage, current, temperature, state of charge (SOC), PCS operating status, and fault alarms cannot be uploaded in real time, making it difficult to promptly detect and address potential hazards. Therefore, a solution is needed to connect these energy storage devices to an IEC104based energy management platform. This requires protocol conversion between Modbus, MQTT, IEC104, OPC UA, etc., as well as device networking, data collection, and protocol translation. WideIOT provides an efficient and reliable energy data acquisition gateway solution.

Key Features

The gateway is equipped with multiple serial and Ethernet ports, supporting connectivity to BMS, PCS, EMS, smart meters, temperature and humidity sensors, voltage and current sensors, cameras, and other devices. It collects device data in real time and supports internet access via 5G, 4G, WiFi, or Ethernet.

The gateway features a rich protocol library, supporting Modbus RTU/TCP, DLT645, CJ188, IEC101/103/104, IEC61850, and other energy protocols. It can convert data to Modbus, MQTT, IEC104, OPC UA, and other protocols for integration with upperlevel systems.

The gateway supports flexible alarm rule configuration. When abnormal data is detected, alerts can be automatically sent via WeChat, SMS, or email, enabling rapid fault localization, diagnosis, and corrective action to ensure safe and stable operation of the energy storage power station.

The gateway features industrialgrade design with wide temperature and voltage tolerance, strong noise immunity, and rugged durability. It also supports network reconnection and data storeandforward functions, ensuring longterm stable operation in outdoor environments while maintaining data integrity and completeness.

The platform enables categorized statistical analysis and visual presentation of energy data. Using an energy data dashboard, users can quickly access information such as device locations, quantities and models, operating status, and process parameters. The platform can also quickly generate data reports for comparative analysis.
