FAQ of Acrel ADW300 3-Phase Wireless Energy Meter

What's the biggest advantage of ADW300?

ADW300 has its built-in wireless communication module which allow it to realize 4G LTE, WiFi, NB-IoT, LoRa upstream communication without using extra IoT gateways. For the application scenarios when the meters can't be of centralized installation, ADW300 will usually be the best option for monitor 3-phase circuits that were far from each other.

How should I deal with RS485 network communication malfunction?

What if LoRa communication of meters malfunctioned?

What's the difference between ADW300 and ADW300W?

What do 3×57.7/100V,3×220/380V,3×380/660V,3×100V,3×380V,3×660V represent respectively?
