Environmental protection inspection exemption for communication base station energy management system

At present, the national standard for electromagnetic radiation protection, "Electromagnetic Radiation Protection Regulations" (GB8702-88), stipulates that when the equivalent radiation power of the electromagnetic radiator is less than 100W (50dBm) within the current mobile communication frequency band, an electromagnetic environment exemption can be implemented; when the equivalent radiation power of the electromagnetic radiator is greater than 100W (50dBm), an "Environmental Impact Report (Form)" should be submitted to the environmental protection department.

Power carrier communication micro inverter

A communication method with strong reliability, low cost and easy maintenance is the key to photovoltaic inverter communication.At present, the most common method is through wireless ( such as WIFI / LoRa ), RS485 and power line carrier ( PLC ) communication.The wireless communication scheme does not need wiring, which can save the investment of communication cable and line laying construction, but it has some harsh environmental requirements, and is obviously blocked by the battery plate and electromagnetic wave interference.
