Overview

In North American 120/208-240V split-phase power systems, energy metering for residential PV, energy storage systems, and single-inverter grid-tied projects has long faced three critical challenges: strict compliance barriers, insufficient metering accuracy, and low deployment efficiency. Conventional meters either fail to adapt to split-phase architectures or lack international certifications — making it difficult to meet the rigorous requirements of overseas markets.

Acrel's AGF-AE-D/200 UL-Certified DIN-Rail Split-Phase Energy Meter is engineered to solve these pain points head-on. Backed by UL 1741 certification, Class 0.5% precision metering, and flexible deployment capabilities, it is the ideal metering solution for North American new energy projects.

Key Advantages

UL 1741 Certified — Seamless North American Market Access

For new energy projects targeting overseas markets, international certification is the gateway to market entry. The AGF-AE-D/200 is purpose-built for North American split-phase systems and certified to UL 1741 (grid-tied equipment safety standard), fully compliant with North American electrical safety regulations and aligned with ANSI C12.20 metering accuracy specifications.

It pairs directly with anti-backfeed controllers and power conversion systems (PCS), meeting the metering data requirements of UL 9540 energy storage system certification. From residential PV grid-tie to commercial & industrial energy storage projects, it enables smooth local utility review and compliant grid interconnection — eliminating compliance risks from the source.

Precision Split-Phase Metering — Full Visibility of Bidirectional Energy Flow

Accurate metering data is fundamental for charge/discharge efficiency analysis and revenue settlement in new energy applications. Equipped with a high-precision metering chip, the AGF-AE-D/200 delivers ±0.5% to ±1% active energy accuracy, precisely capturing bidirectional energy flow with over 60% lower error compared to conventional meters.

Designed exclusively for split-phase systems, it measures full electrical parameters in real time — voltage, current, power, power factor, and more — while supporting four-quadrant energy metering and sliding window demand statistics. For the load imbalance issues common in split-phase systems, it dynamically displays phase-by-phase load distribution, enabling rapid identification of overloads and harmonic distortion to prevent equipment damage and energy waste.

Fast Deployment & Smart Integration — Built for Diverse Applications

In new energy projects, equipment compatibility and installation convenience directly impact operational efficiency. The AGF-AE-D/200 features standard 35mm DIN-rail mounting with a compact footprint (54.1 × 87.8 × 52mm), fitting easily into battery cabinets, PCS enclosures, and existing distribution panels — no major retrofitting required, significantly reducing installation costs.

Paired with split-core current transformers supporting 0–200A high-current input, the tool-free, no-disconnection design makes retrofitting existing projects safe and efficient — complete deployment in as little as 10 minutes.

On the communication side, it features an RS485 interface (Modbus-RTU protocol) with SunSpec protocol support, seamlessly integrating with energy storage management systems (ES), microgrid energy management systems, and cloud platforms for high-speed data refresh and remote automated meter reading. With a ≤1s response time, it rapidly detects backfeed signals and triggers inverter power adjustment — providing sufficient response margin for anti-backfeed control and ensuring safe, stable system operation.

Industrial-Grade Reliability — Built for Harsh Conditions

New energy projects operate in challenging environments — temperature extremes, humidity, and electromagnetic interference demand robust equipment performance. The AGF-AE-D/200 uses industrial-grade components with a wide operating temperature range of -30°C to +70°C and IP52 ingress protection, standing up to the harsh conditions of energy storage containers and outdoor distribution cabinets. Strong electromagnetic interference resistance ensures stable, reliable long-term operation.

With ultra-low power consumption (≤1.2W) and maintenance-free design, backed by Acrel's established technical service network, it supports both large-scale batch deployments and small-scale retrofit projects — optimizing total cost of ownership across the full product lifecycle.
