Prepaid Energy Meters for STS Applications

STS prepaid meter selection should begin with the electrical configuration, installation method and prepaid-system architecture. Confirm the phase and wiring, voltage and current range, keypad or CIU arrangement, customer interface, token or vending workflow, communication requirements, target market, required documentation and pilot acceptance criteria before selecting the final meter model.

No. The prepaid meter hardware does not automatically include vending, payment, key-management, customer-account, SIM/data, API, SDK or backend services. These functions may belong to separate software, service or system-integration scopes, so ownership, interfaces and responsibilities should be defined before the project is approved.

No. A prepaid meter should not be treated as STS-compatible unless the exact product, configuration and applicable documentation have been verified for the project. STS-related requirements can depend on the meter platform, token or key-management arrangement, customer interface, target market and system architecture. Buyers should confirm the exact model and supporting documents before project selection.

An integrated-keypad meter places the customer input interface on the meter itself, while a split-meter design separates the metering unit from the customer interface unit (CIU). The preferred architecture depends on installation location, customer access, tamper-management strategy, wiring or communication arrangement, property layout and the intended operating workflow.
