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.
Our Advantages
Risesun is one of the companies with the most technical influence
and development potential in the electric energy metering
instrument industry of China.and is one of the earliest enterprises

ISO9001:2008, ISO14001: 2004 and OHSAS18001: 2007. With its brand
and other comprehensive advantages,Risesun has been elected as the
director unit of China Instrument and Meter Industry Association,
and the member unit of the national standard revision group of
National Standards Technical Committee for Electrical Measuring
Instruments.Besides, Risesun has already achieved 36 utility model
patents, a number of invention patents and 15 software copyrights.
Several RD projects of Risesun have got the grants and awards from
the provincial and municipal governments in Zhejiang Province.
Today's Risesun, just as a round of Oriental Sun, is rising and
creating greater glories with the help of the national macroscopic
policy good solution and its research and development potential.
