LoRa Data Transmission Remote Control System Solution for Photovoltaic Power Stations

Published: 2026-06-15 11:01:01

As industrial and commercial photovoltaic (PV) power stations are increasingly connected to the grid, power quality issues such as reverse overload, high daytime voltage, and low nighttime voltage have become frequent. In particular, under the "full selfconsumption" mode, antireverse power flow control has become critical to the safe operation of PV stations. A certain industrial park has deployed an antireverse power flow control unit and wants to achieve power control over multiple inverters. However, the deployment cost of wired solutions is high, and the construction period is long. Therefore, the park is seeking a wireless data transmission solution.

 

In response, WideIOT has launched a PV station data acquisition and transmission solution based on LoRa gateways. By deploying LoRa terminals on the inverter side, the solution collects inverter operation data and transmits it to the WideIOT LoRa gateway. The gateway then communicates with the antireverse power flow control unit to achieve flexible regulation of inverter output power and rigid control via circuit breakers, effectively realizing antireverse power flow protection, remote monitoring, and intelligent maintenance.

Key Features

LoRa gateways and terminals support RS485/RS232 interfaces and can acquire data using common power communication protocols such as Modbus, DLT645, and IEC101/103/104. They also support various internet access methods including 5G, 4G, WiFi, and Ethernet.

A cloudbased data dashboard displays realtime data for each inverter, including AC/DC voltage and current, instantaneous power, daily energy yield, and device temperature. A graphical overview of the entire station’s power generation efficiency and energy flow is also available.

Based on realtime power data reported from the grid connection point, the antireverse power flow control unit can issue power regulation commands to the inverters, or control circuit breakers via the terminal’s I/O ports, dynamically limiting output to prevent reverse power flow back to the grid.

When the gateway detects abnormal inverter parameters, the system automatically sends alarm notifications via WeChat, SMS, or email, and creates inspection or maintenance work orders on the O&M platform to guide managers in responding quickly.

Daily and monthly reports can be generated to compare historical solar irradiation data with power generation, accurately calculate the performance ratio (PR), and uate module degradation and equipment efficiency. This provides datadriven support for actions such as module cleaning, replacement of underperforming equipment, and optimized spare parts management.
