The Secure Saral 305 3 Phase Net Meter is a next-generation, three-phase, four-wire direct-connected digital energy meter developed by Secure Meters for precise electrical energy measurement and net metering applications. It operates by continuously sampling phase voltages and line currents across a 5–100A direct-connected range, recording both imported grid energy and exported solar energy in configurable tariff registers.
This meter is engineered for solar EPC contractors, commercial building owners, industrial facility managers, utility sub-metering operators, and residential three-phase consumers. In Bangladesh, where rooftop on-grid solar installations and three-phase commercial sub-metering are expanding rapidly under utility net metering guidelines, the Saral 305 provides dependable bidirectional energy accounting, anti-tamper protection, and remote data retrieval.
Direct-Connected 3-Phase 4-Wire Architecture: Eliminates external current transformers (CTs) for loads up to 100A, simplifying panel installation.
Class 1.0 Metrological Accuracy: Delivers reliable, utility-grade active energy measurement for billing and energy auditing.
Bidirectional Net Metering & Configurable Tariffs: Tracks energy import/export with programmable Time-of-Use (ToU) tariff registers and load-profile recording.
Comprehensive Anti-Tamper Protection: Detects magnetic interference, cover opening, phase reversal, and neutral disturbance to protect revenue integrity.
Flexible Communication Interfaces: Equipped with an optical communication port, optional Bluetooth Low Energy (BLE), and support for a terminal-fitted modem for automated remote meter reading (AMR).
High Measurement Precision: Class 1.0 accuracy ensures minimal measurement drift across varying load conditions from 5A up to 100A.
Durable IP54 Enclosure: Ingress-protected housing resists dust accumulation and water splashes in indoor electrical rooms and outdoor meter boxes.
Advanced Revenue & Tamper Security: Built-in event logging and multi-parameter tamper detection prevent unauthorized bypass or manipulation.
Energy Management & Load Profiling: Detailed load-profile memory enables engineers to analyze peak demand, power consumption patterns, and solar export efficiency.
Low Maintenance & Direct Wiring: Solid-state electronic metrology with direct terminal connections eliminates mechanical wear and reduces installation complexity.
Residential: Three-phase apartment buildings, duplex homes, and rooftop on-grid solar net metering connections.
Commercial: Shopping complexes, retail outlets, hospitals, hotels, and multi-tenant commercial sub-metering.
Industrial & Factory: Small-to-medium manufacturing units, workshop distribution boards, and machinery energy monitoring up to 100A per phase.
Office: Corporate office floors, IT parks, and commercial buildings requiring tenant sub-metering and tariff tracking.
Project Installation: On-grid solar PV net metering projects, EPC turnkey electrical panels, and utility distribution upgrades.
