ADL400W-CT/WF balcony photovoltaic anti backflow bidirectional metering meterMain functions

Full parameter high-precision measurement and metrologyIt can accurately measure more than ten types of power parameters, including voltage, current, active power, reactive power, apparent power, power factor, frequency, etc., with a measurement accuracy of ± 0.5%. At the same time, it can measure the current combination of active energy, as well as forward and reverse active and reactive energy, which meets the B-level (national standard level 1) error level. It is like equipping the new energy system with an accurate "energy ledger" to clearly record various flow data of electricity.

Millisecond level anti backflow and intelligent regulationThe response rate is as fast as 100ms, far exceeding the EU's requirement of 2 seconds. When a reverse flow trend of electricity is detected, the inverter can be quickly linked to trigger load shedding and other operations to avoid the impact of reverse flow on the power grid. In addition, it can also communicate with the Energy Management System (EMS) to complete operations such as power generation regulation and battery charging and discharging control based on real-time power and cumulative energy data, ensuring the compliant and efficient operation of the new energy system.

Convenient communication and data managementEquipped with RS485 communication interface, supporting MODBUS RTU communication protocol, and the baud rate can be flexibly set between 1200-38400bps. It is compatible with inverter specific protocols such as SMA and SolarEdge, and also supports remote 4G (MQTT) communication, which enables remote data transmission and reading, as well as convenient access to smart home apps or cloud management platforms. And it is equipped with a built-in supercapacitor, which can store data for no less than 1 year after power failure, meeting the long-term data traceability needs.

Fault self diagnosis and convenient installation adaptationEquipped with fault self diagnosis capability, it can automatically detect issues such as transformer detachment and phase sequence errors, and provide dual alarms through screen icons and text messages, facilitating remote troubleshooting. Adopting DIN35mm guide rail installation, combined with a switchable transformer, installation can be carried out without power outage or wire breakage, greatly simplifying the process of retrofitting old systems, improving installation efficiency, and reducing construction costs.

ADL400W-CT/WF balcony photovoltaic anti backflow bidirectional metering meterApplication scenarios

Distributed photovoltaic systems for household and commercial useWhether it is a 1-3kW German household micro reverse photovoltaic project or a 10MW industrial park photovoltaic project, this meter can accurately measure the photovoltaic power generation, self consumption, and surplus electricity situation. On the one hand, it helps users meet local policies and requirements such as "zero access to surplus electricity" and avoid fines for backflow; On the other hand, it provides accurate measurement data support for users to apply for new energy subsidies.

Energy Storage SystemSuitable for industrial and commercial energy storage as well as household energy storage scenarios of 10-50kW, it can monitor real-time data such as voltage, current, and power during the charging and discharging process of energy storage equipment, providing a basis for optimizing the charging and discharging strategies of energy storage systems. For example, Texas users in the United States have achieved an annual arbitrage profit of over $800 by implementing a "self initiated self use priority+peak valley arbitrage" strategy; The Los Angeles supermarket uses this meter to control the energy storage system, with valley charging and peak discharging, significantly reducing the project payback period.

Micro inverse and AC coupling systemAdapt to the energy metering needs of distributed low-power generation units, support multi unit data aggregation and remote monitoring. When paired with a micro reverse system for small-sized residential units in Tokyo, its compact size can easily be embedded in a distribution box, while efficiently completing the energy metering and control of such systems, improving the system's spontaneous self use rate.

Other new energy and supporting scenariosIn the off grid photovoltaic scenario in Southeast Asia, the electrical energy situation of diesel generators and photovoltaic complementary systems can be monitored to avoid reverse flow burning equipment and reduce diesel consumption costs; In the scenario of electric vehicle charging stations, it can prevent charging piles from reversing power to the grid, while protecting vehicle batteries and reducing the failure rate of charging equipment during voltage fluctuations in the grid.
