I. Core Value of Integrated Prepaid System

1.1 Definition of Integrated Prepaid System

The integrated prepaid system integrates energy meters, communication networks and charging management platforms into a complete power consumption management system. Users recharge and purchase electricity in advance, and the system automatically manages the whole process including metering, fee deduction and power control. It is an important application branch of AMI (Advanced Metering Infrastructure).

1.2 Embodied Core Values

• Cost Control: The pay-first, use-later mode effectively avoids electricity fee arrears and reduces capital risks for operators. It is particularly critical for property management, rental housing, commercial parks and similar scenarios.
• Management Efficiency: The integrated prepaid meter system supports remote meter reading and remote recharging, greatly reducing manual workload for meter reading and fee collection.
• Transparent Power Consumption: Users can query remaining electricity balance and historical power records at any time. Clear and visible power usage helps cultivate energy-saving habits.
• Data Support: Accumulated power consumption data provides solid support for energy consumption analysis, load forecasting and equipment maintenance.

II. Core Components of Prepaid System

2.1 Energy Meter Terminal

The energy meter is the front-end metering device of the prepaid system, responsible for real-time collection of power consumption data. Single-phase or three-phase meters can be selected according to application scenarios. Smart meter manufacturers normally provide various specifications to meet demands of different voltage levels and current capacities.

Basic mandatory functions of energy meters:

• Accurate active energy metering (compliant with IEC 62053-21 or corresponding national standards)
• Remaining electricity / balance display
• Low power early warning
• Power cut-off protection upon electricity exhaustion (compliant with local regulations)
• Data storage and communication upload (supports DLMS/COSEM protocol)

2.2 Communication Network

The communication network acts as a bridge connecting energy meters and the management platform. Common communication methods are as follows:

Wired Communication: RS485 bus, Ethernet, etc. Suitable for centrally installed meters with high stability but higher wiring costs.

Wireless Communication: NB-IoT, Cat.1, 4G LTE and other cellular networks. Ideal for scattered meter installation; no wiring required, while signal coverage and operator tariffs need to be considered.

Power Line Carrier (PLC): Transmits data via existing power lines without additional wiring. Narrowband PLC (such as G3-PLC, PRIME) is applicable for meter reading systems; broadband PLC supports high-speed data transmission.

Smart meter suppliers recommend the most suitable communication solution based on project conditions, local communication infrastructure and budget.

2.3 Charging Management Platform

As the core of the prepaid system, the charging management platform undertakes user management, recharge processing, data statistics and other functions. Main modules include:

• User Management: Account opening, cancellation and information modification.
• Recharge Management: Multiple recharge channels including business hall, mobile APP and self-service terminals.
• Billing Management: Supports flat tariff, tiered tariff, time-of-use tariff and other billing modes.
• Report Statistics: Reports on power consumption, fee collection and abnormal power consumption analysis.
• Permission Management: Role-based access control to ensure system security.
• AMI Integration: The platform can be integrated with the master station system for data exchange via DLMS/COSEM protocol.

III. Key Links of System Implementation

3.1 Demand Research

Before project implementation, the smart meter company communicates fully with the client to confirm:

• Project scale (meter quantity and distribution)
• Power consumption type (residential, commercial, industrial)
• Management requirements (remote meter reading & remote recharge or not)
• Target market and applicable standards (domestic / overseas, IEC / ANSI, etc.)
• Budget range
• Delivery cycle requirements

3.2 Solution Design

Based on demand research, the technical team delivers a detailed system design scheme, including:

• Energy meter selection recommendation (accuracy class, communication mode, protection grade)
• Communication solution recommendation and network topology
• Platform function configuration
• Compliance requirements (certifications & standards)
• Implementation schedule

3.3 Installation & Commissioning

Meters shall be installed by professional technicians to ensure correct wiring and firm fixation. Signal testing is conducted for the communication network to guarantee stable data transmission. The management platform completes parameter configuration and user data import.

3.4 Training & Delivery

Before system handover, professional training is provided for operators covering platform operation, daily maintenance and troubleshooting, enabling proficient system use.

IV. Typical Application Scenarios

4.1 Rental Housing Management

Landlords realize unified power management of multiple rental properties via the prepaid system. Tenants recharge independently to avoid electricity fee disputes.

4.2 Commercial Property

Shopping malls, office buildings and other commercial properties adopt prepaid systems for individual metering and independent charging of each merchant, reducing property management costs.

4.3 Industrial Parks

With numerous enterprises and complex power consumption, industrial parks adopt prepaid systems to achieve independent metering and cost control for each settled company.

4.4 Campus Dormitories

Prepaid meters are widely applied in school dormitories. Students recharge for electricity use, facilitating unified campus management.

4.5 Agricultural Irrigation

Agricultural power consumption is seasonal and scattered. The prepaid system allows farmers to purchase electricity on demand and reduces management difficulties for power suppliers.

4.6 Overseas Market Projects

Power infrastructure projects in Asia, Africa and Latin America have strong demand for prepaid systems, with special attention to local power regulations and certification requirements.

V. Key Factors for Selecting a Smart Meter Supplier

5.1 Product Quality

The quality of electronic meters directly determines system operational stability. It is recommended to verify the supplier’s production process, quality inspection procedures and past project references.

5.2 Technical Capability

The prepaid system covers energy metering, communication technology, software development and other fields. The supplier’s technical integration capability, especially AMI system integration experience, is essential.

5.3 After-sales Service

Various problems may occur during system operation. A complete after-sales service system reduces operational risks. It is advised to check response time, service network coverage and warranty period.

5.4 Cost Performance

On the premise of meeting technical and quality standards, comprehensively evaluate procurement cost, installation cost and operation & maintenance cost to select the optimal cost-performance solution.

Conclusion

The integrated solution of energy meter prepaid system represents an important development trend in power metering and management. Choosing a reliable smart meter supplier matters not only to product quality, but also to long-term stable system operation and sustainable services.
