Problem: Challenges Faced by Utilities in Electricity Revenue Management
Many power utilities and energy service providers face challenges such as inefficient electricity collection, high manual meter reading costs, delayed payment recovery, and limited visibility of customer electricity consumption. Traditional electricity meters cannot effectively support flexible billing models, prepaid electricity management, or remote monitoring requirements for modern smart grid applications.
Solution: Hexcell Single Phase Prepaid/Postpaid Smart Energy Meter
Hexcell Single Phase Card Prepaid/Postpaid Energy Meter (DDSY1088/DDS1088) provides a reliable solution for efficient electricity management by supporting both prepaid and postpaid operating modes.
With prepaid functionality, customers can purchase electricity credits before consumption through IC cards, enabling utilities to improve revenue collection and reduce payment risks. The meter also supports postpaid operation, allowing flexible deployment according to different utility business models and regional requirements.
The meter integrates advanced metering, tariff management, load control, and communication technologies to help utilities achieve digital electricity management. Through optional communication interfaces such as RS485, LoRa, and infrared communication, the meter can connect with AMI (Advanced Metering Infrastructure) systems for remote data collection, centralized monitoring, and energy consumption analysis.
Evidence: Reliable Technology and Proven Smart Metering Features
Accurate measurement of forward/reverse active and reactive energy
Storage of up to 12 months of electricity consumption data
Support for multiple tariff strategies, including seasonal tariff, weekly tariff, daily period tariff, and holiday tariff management
Automatic switch-off under insufficient credit conditions and flexible prepaid/postpaid mode switching
Event recording for recharge, power failure, cover opening, reverse energy, undervoltage, and overvoltage conditions
Remote communication capability for AMI system integration
With high reliability, long service life, and compliance with IEC and international certification requirements, Hexcell Single Phase Prepaid/Postpaid Energy Meter is widely applied in residential communities, apartments, factories, shopping malls, office buildings, hotels, and photovoltaic power generation projects.
It helps utilities improve electricity revenue management, reduce operational costs, and accelerate smart grid transformation.
