3. Commonly used communication technologies for inverters
As the brain of the entire power station, the photovoltaic inverter can transmit the collected power station operation data to the communication hardware. Operation and maintenance personnel or users can view relevant data through the intelligent operation and maintenance platform to realize intelligent management of the power station. So how does the inverter transmit data? What are the different communication methods for the applications of inverter?
- GPRS/4G communication
Generally, each inverter is equipped with a GPRS/4G data collection module. Through the built-in SIM card, the collected data is uploaded to the inverter company's server through the wireless network and the communication base station. This method is easy to use and does not require additional wiring, but traffic charges is needed.
Applications of inverter with GPRS/4G communication: Suitable for medium and large distributed projects and areas with good signal coverage by service providers.
- WiFi communication
Generally, the inverter is connected to the router through a built-in or external WiFi module, and the collected data is transmitted to the inverter company's server. It can also be directly connected to the mobile phone APP through WiFi for data interaction. This method is easy to install and requires no traffic charges, but it requires stable wireless network coverage, so it is greatly affected by external factors such as distance and weather.
