New Upgrade for Electric Meters | ADW300A Wireless Electric Meter: 15-Minute Data Freeze + Bluetooth Debugging + One-Click Operation, Maximize O&M Efficiency!

Acrel ADW300A wireless metering instrument has been fully upgraded. It solves pain points in scenarios including low-voltage power distribution, charging piles, energy storage and industrial & commercial energy consumption monitoring. With three core upgrades, it makes the whole process of installation, commissioning, operation & maintenance and settlement more convenient, efficient and compliant.

To be precise, what is canceled is the administratively led fixed time-of-use electricity price, rather than the time-of-use electricity price mechanism itself. The core of the reform is shifting from government-unified delineation of peak-valley periods and floating ratios to market supply and demand independently determining prices within 15-minute time windows. For power users, electricity bills are no longer fixed and predictable, and billing granularity keeps getting finer. Traditional meter billing systems relying on monthly meter reading or fixed-period deduction can no longer adapt to the new trend. Failure to keep metering methods in pace with market changes will lead to inaccurate billing at the least, and tenant disputes as well as electricity fee deficits at worst.

Against the market-oriented electricity price reform trend, backed by nearly 20 years of profound experience in energy efficiency management, Acrel has taken the lead in launching an integrated solution combining ADW300A wireless metering instruments and prepaid cloud platforms. It fully adapts to dynamic electricity price billing demands from the perception layer to the application layer, delivering a full-process closed-loop management covering accurate metering, flexible pricing and efficient charging for commercial complexes, industrial parks, campus dormitories, charging stations and other scenarios.

In the era of market-driven electricity prices, the top priority of all market players is to match electricity consumption data with corresponding time accurately. Tailored exactly for this demand, the Acrel ADW300A wireless metering instrument is a multi-functional wireless meter designed for low-voltage power distribution networks. Featuring compact size and DIN rail mounting, it supports external split-core current transformers and Rogowski coils, easily adapting to complex on-site conditions such as conventional wiring, high current and wide copper busbars. It is compatible with multiple communication modes including RS485, LoRa/LoRaWAN, 4G and WiFi, satisfying the needs of precise metering, intelligent monitoring and convenient operation and maintenance simultaneously.

Minute-Level Energy Data Freeze to Keep Pace with Fluctuating Electricity Prices

The newly added minute-level energy data freeze function enables the ADW300A to adopt a 15-minute freezing cycle, ensuring high-precision power data can be fully traced for a whole year. It also supports daily and monthly data freeze to meet data statistics and traceability requirements of different cycles. Equipped with storage capacity for historical power data of the past 12 months (including power data of 8 tariff rates respectively), it provides solid data support for auditing, supervision and dispute settlement.

The shift from unified fixed pricing to market-driven floating electricity prices has become an irreversible industrial trend. For operation managers of millions of commercial complexes, industrial parks and office buildings nationwide, this brings both challenges and opportunities. Those who can quickly align their billing systems with minute-level fluctuating electricity prices will seize the initiative in refined operation management.

The integrated solution of Acrel ADW300A minute-level freeze electric meters and prepaid cloud platforms provides a complete closed-loop solution ranging from accurate data collection to efficient fee collection for every kilowatt-hour of electricity in the dynamic electricity price era.
