ESEP System:

The system is the core of Holley AMI solution. ESEP uses a hybrid B/S and C/S system which based on .NET/Java architecture and the topological graph, and integrates web-based data management as its core business. ESEP system is that measure, collect, and analyze energy usage, and communicate with metering devices, either on request or on a schedule.
● MDM system is using for collect smart meter data and storage to database, through process meter demand data, energy data, instantaneous data and billing data, provide data analysis and line loss analysis result or report to customer.

● Prepayment system is a flexible vending system that supports different vending channels and medium. This system helps utility to facilitate the route of Meter-to-Billing and Billing-to-Cash, improves their liquidity and guarantees their investment.

● Holley AMI system can be integrated with third-party interface (API) such as banks or billing companies to provide value-added services, providing a variety of sales methods and 24 hours a day service. Through the interface to get the data, do the recharge, relay control and meter data management.
