Frequently Asked Questions

Q: What is the main operational advantage of your smart electricity meters over traditional meters?

A: Our smart meters feature integrated two-way communication modules (such as NB-IoT, LoRaWAN, or 4G) and built-in load switches. This allows grid operators and property managers to conduct remote automatic meter reading (AMR), change tariffs remotely, monitor real-time power quality parameters, and disconnect/reconnect power remotely without sending field technicians.

Q: Do your smart meters support the DLMS/COSEM protocol?

A: Yes. Our utility-grade smart meters fully support the DLMS/COSEM (IEC 62056) global standard. This guarantees seamless interoperability, allowing our meters to integrate directly with third-party Head-End Systems (HES) and Meter Data Management (MDM) platforms.

Q: How do your prepaid meters handle token vending and secure top-ups?

A: Our prepaid electricity meters utilize the internationally recognized STS (Standard Transfer Specification) encryption standard. Tokens can be generated via compliant vending software and entered into the meter via an integrated or remote keypad (UIU). We also support RFID smart card prepaid systems for commercial sub-metering.

Q: Can you customize the meter's communication protocols for localized AMR/AMI projects?

A: Absolutely. Through our ODM services, we can modify the communication module to support your exact infrastructure—whether that involves hardwired RS485 Modbus for industrial automation or wireless cellular networks (NB-IoT/4G) for widespread utility deployment.

Q: What is your standard production lead time and warranty for international utility tenders?

A: Standard lead times typically range from 3 to 5 weeks, depending on the order volume and customization requirements. For international infrastructure and utility projects, we provide a standard 2-to-5-year warranty coupled with continuous lifecycle technical support and remote firmware upgrade (OTA) capabilities.
