Sub-Metering & Billing System

A centralized system for monitoring energy consumption and managing utility billing across multiple tenants, departments, or facilities. It enables accurate sub-metering, flexible tariff configuration, account management, and automated billing processes to support transparent and efficient energy cost allocation.
Typical Application

   Shopping Mall Tenant Billing

Monitor and allocate energy consumption for individual retail stores to support transparent tenant billing and operational cost management.


  Multi-Tenant Commercial Buildings

Measure and manage electricity usage for multiple tenants within the same building to enable fair energy allocation and billing.


   Industrial Park Utility Billing

Track energy consumption across multiple companies or factories and provide centralized monitoring with accurate utility cost distribution.


 Dormitory & Rental Electricity Billing

Manage prepaid electricity accounts and monitor energy usage for individual rooms or residents to support automated billing and usage control.


System Architecture Overview

A structured, three-layer architecture that connects field data, communication infrastructure, and application-level analytics.

System Goals

Application & Operations Layer- Base System Package

The standard core configuration included in every system package—extend with optional modules when needed.

Platform Configuration
