Q&A

Q: What are the differences between smart energy meter and ordinary energy meter?

A: Compared with previous energy meters, smart energy meter has the bidirectional metering function and supports the distributed energy utilization. it can record the import and the export energy. If the user is self-built with distributed clean energy generation facilities, such as wind energy, solar energy, etc., it can realize to transmit the spare energy to power grid when the generated power cannot be exhausted, thus achieve energy conservation and environmental protection to reduce carbon dioxide emissions, create low carbon life and improve the users' economic benefits.
