Photovoltaic Meter and Inverter Data Collection Solution

Published: 2026-04-28 10:39:44

A company operates multiple photovoltaic power plants across different provinces and regions. Due to the long distances and decentralized locations, manual data collection has proven to be costly and inefficient. Additionally, grid-connected data cannot be quickly compiled or reviewed, which significantly impacts work efficiency and operational management. Therefore, a solution is needed to collect data from photovoltaic power plants and upload it to an IoT platform. The data collection involves equipment such as PV generation meters, PV inverters, and box-type substation monitoring terminals, enabling centralized monitoring and management.

 

Currently, the inverters at each power plant are connected via a bus to the box-type substation monitoring terminal in the grid-connected cabinet. Along with smart meters, all communication protocols are IEC104. By connecting WideIOT industrial IoT gateways, real-time data such as power generation, current, voltage, and power can be collected and transmitted over 4G networks to the PV power plant IoT platform. This enables remote monitoring, statistical analysis, and data visualization, providing various functional applications.

Key Features

1. Real-time Monitoring – Monitor power generation, voltage, current, and power data in real time across each PV power plant. The system automatically aggregates data and generates visual data reports and power generation trend curves, offering a clear view of plant operation and providing accurate data support for optimizing generation efficiency.

 

2. Customizable Alerts – Set up flexible alert rules. When abnormal data is detected, the system sends alerts to operation and maintenance personnel via SMS, email, or WeChat. Each alert clearly identifies the faulty equipment location and abnormal parameter type, ensuring timely troubleshooting and repair.

 

3. Data Analysis & Decision Support – Combine historical power generation data with environmental factors (e.g., season, weather) to analyze efficiency differences in PV components across different time periods and regions. The system also calculates and records billed grid-connected power generation, providing a scientific basis for optimizing business strategies.
