Manufacturers of small rural PV power stations have long faced three major challenges in aftersales maintenance: widely dispersed sites, delayed fault detection, and maintenance costs that outweigh profits. Since villagelevel PV stations are typically installed on farmers' rooftops or in remote rural areas—many in small scale but scattered across large distances—faults often go unnoticed and unresolved for long periods. At the same time, equipment manufacturers need to establish an informationbased maintenance management system to improve work efficiency and management capabilities.

To address these pain points—many sites spread over large areas, with few staff and long travel distances—WideIOT has deployed industrial IoT gateways that connect to inverters (supporting 4G/5G communication). These gateways collect key parameters in real time, including DC input voltage/current, AC output voltage/current, instantaneous power generation, cumulative power generation, equipment temperature, and fault alarm codes. The data is then uploaded to a cloud platform via the MQTT protocol. Manufacturers or maintenance centers can log in to the platform from a computer or mobile phone to check the operating status of equipment installed across different villages and take quick action to manage and control the system.

Key Features

The gateway is equipped with multiple communication ports, including serial ports, Ethernet ports, and I/O ports. It supports protocols such as IEC 101/103/104, IEC 61850, Modbus, OPC UA, and DLT645. Data can be transmitted over 5G/4G, WiFi, or Ethernet.

Organized by individual power station, the system displays realtime data for each site, including DC input voltage/current, AC output voltage/current, instantaneous power generation, cumulative power generation, equipment temperature, and fault alarm codes. Visual formats such as line charts and bar charts are supported.

Users can set custom alarm thresholds. The system automatically detects anomalies and pushes alert notifications via WeChat, SMS, or email. This allows for quick identification of faulty equipment, abnormal data, timestamps, and other critical information.

The platform supports the full maintenance workflow: creating, editing, reviewing, rejecting, and accepting service work orders. It enables realtime tracking of progress, operation logs, and assigned personnel, helping to quickly allocate maintenance resources, improve work efficiency, and raise management standards.
