With the explosive growth of distributed photovoltaic (PV) installation capacity, power station management is facing increasing complexity—marked by a large number of stations, widespread distribution, mixed equipment brands, and chaotic data management. On one hand, enterprise managers need real-time visibility of inverter operating status across different geographical locations. On the other hand, grid dispatch authorities are requiring distributed PV systems to be observable, measurable, adjustable, and controllable. However, under the traditional model, power station data is often uploaded only to the manufacturer’s private cloud, leaving grid operators blind and unable to regulate effectively—resulting in severe data silos and control blind spots.

To address these challenges, WideIOT has launched a multi-center data acquisition and transmission system built around its PV protocol converter. This device supports connection to inverters from major brands (using protocols such as IEC101/103/104, IEC61850, Modbus RTU/TCP, etc.), and collects key parameters in real time—including power generation, DC voltage and current, AC power, equipment temperature, and fault alarms. The system can simultaneously report data to multiple data centers (such as the grid dispatch center, enterprise operation and maintenance platforms, and third-party supervisory platforms). This "one-to-many" transmission and data sharing capability ensures both regulatory compliance and efficient operation and maintenance.

Key Features

1. Multi-Protocol Data Acquisition – Equipped with RS485/RS232 serial ports and Ethernet ports, the system can collect data from various inverters and energy devices using protocols such as DLT645, IEC101/103/104, IEC61850, and Modbus. Uplink support includes Modbus, MQTT, IEC104, OPC UA, and more, enabling easy integration with different management system platforms.

2. Simultaneous Multi-Platform Reporting – Inverter data can be transmitted via 5G/4G/WiFi/Ethernet to both the grid dispatch center and the enterprise’s private cloud at the same time, achieving one-to-two data reporting. This allows grid operators to monitor and regulate inverter status in real time, while enterprises and users can view power generation revenue, equipment health status, and other key metrics.

3. Automated Alerts and Work Order Management – When abnormal parameters are detected (e.g., voltage exceeding limits or overheating), the system automatically sends alerts via WeChat, SMS, or email. It can also generate inspection or maintenance work orders on the enterprise O&M platform to guide rapid fault resolution. Additionally, the system aggregates data to create visual dashboards, clearly displaying overall plant efficiency and energy flow.

4. Industrial-Grade Durability – Designed for harsh outdoor environments, the system features wide temperature and wide voltage tolerance, strong interference immunity, rugged construction, and low power consumption. It also supports network disconnection recovery, data resumption after interruptions, local data caching, and cloud database transmission—ensuring data integrity is maintained even in extreme conditions.
