Net energy metering (NEM) mode
Import (forward) only mode
Over-voltage recording
Under-voltage recording
Sag
Swell
30 minutes load profile for 40 days or
15 minutes load profile for 20 days
Time of use (TOU) up to 8 rates, daily, weekly, seasonal and special

Advanced Metering Infrastructure (AMI) capabilities

exchangeable communication modules (plug & play)
self-register (auto-register) function
self-healing function
high compatibility with 3rd party systems
DLMS/COSEM compliance
STS payment mode can be set in the meter, the tokens are generated with PRISM security modules and submitted by the AMI system

The firmware can be upgraded locally or by remote. The meter has a sealable battery. A extra battery supports the real time clock (RTC). The CL710K20 has a modular design without any internal wiring. The display can be read without power.
