Lte Cat 4 Modem Networking for Photovoltaic Application Solutions

Photovoltaic power generation systems usually face the problems of data acquisition and remote monitoring, and the Lte cat 4 modem (data transmission unit) can play a role at this time. The LTE Cat 4 modems can connect the data acquisition equipment in the photovoltaic system with the cloud platform or local computer to realize real-time monitoring and data transmission.

Specific PV application solutions can be divided into the following steps:

1. Installation of data acquisition equipment: install data acquisition equipment in the photovoltaic system, including power meters, weather stations, temperature sensors, etc., to collect the operation data of the photovoltaic system.

2. Connect LTE cat 4 modems: connect data acquisition devices such as instruments and sensors with the LTE cat 4 modem, which can transmit data to the cloud platform or local computer through GPRS, 3G, 4G, Cat-1, or Ethernet.

3. Data transmission and storage: After receiving the data, the cloud platform or local computer processes and stores the data, and realizes the remote monitoring and management of the photovoltaic system through the Web interface or app terminal.

4. Fault warning and maintenance: Through the analysis of PV system data, fault warning, and maintenance can be achieved, and the operation efficiency and reliability of the PV system can be improved.

Generally speaking, photovoltaic power generation system includes solar panels, charge controllers, battery packs, inverters, and other parts. By installing LTE cat 4 modem equipment, real-time monitoring and control of these parts can be realized, including:

● Solar panel: monitor the voltage, current, temperature, and other parameters of the panel, so as to find faults and abnormalities in time.

● Charging controller: monitor the voltage, current, charging state, and other parameters of the battery pack to ensure the safe and stable operation of the battery pack.

● Battery pack: monitor the voltage, current, temperature, and other parameters of the battery pack, so as to find faults and abnormalities in time.

● Inverter: monitor the voltage, current, frequency, and other parameters of the inverter to ensure the normal operation of the inverter.

Through the LTE cat 4 modem device, the monitoring data can be transmitted to a remote server for analysis and processing. At the same time, the remote control of photovoltaic power generation system can also be realized through LTE cat 4 modem equipment, including:

The charge controller is remotely set and adjusted to ensure the state of charge and safety of the battery pack.

The inverter is remotely set and adjusted to ensure that the output voltage and frequency of the inverter meet the requirements.

Remote monitoring and management of the entire photovoltaic power generation system, including alarm and fault handling.

To sum up, the photovoltaic application solution based on LTE cat 4 modem networking can realize the remote monitoring and control of the photovoltaic power generation system, improve the safety and stability of the system, reduce the maintenance cost, and promote the development of photovoltaic applications.
