semparuti.combiner box monitoring system (power line communication), support 1000V / 1500V PV system, real-time monitoring of the string current, bus voltage, combiner box temperature, switch status, etc., alarm output when data is abnormal . p>
Advantages of power line communication (PLC): no need for communication wiring, communication quality is stable and reliable.
华体网即时比分The advantages of power line communication (PLC) compared to Lora communication: Since Lora uses shared bandwidth, many factors affect the quality of communication: for example: intercom, weather, occlusion, etc. but power line communication (PLC) as long as the construction can be connected As long as it is connected, the power line communication is more stable and reliable than the Lora communication.
