In response to these pain points, Acrel has launched a scenario-based product matrix to realize the strategy of one scenario, one solution.

4. Product Matrix and Scenario Adaptation

All-Round Core Product: DJSF1352/RN

As a flagship product adaptable to all scenarios, the DJSF1352-RN supports dual-channel DC input, with flexible adjustable voltage and current parameters. It is equipped with a ±12V voltage output, which can directly power Hall sensors and simplify system deployment.

The product has obtained three authoritative certifications: CPA, CE and UL. It integrates multiple communication protocols including Modbus-RTU, DLT645-07, DLT698 and YD1363, making it suitable for charging piles, energy storage systems, communication base stations, DC power distribution and other scenarios to achieve seamless integration.

Special Type for High-Voltage Energy Storage: DJSF1352-RN-6

Focusing on the demands of 1500V high-voltage energy storage and photovoltaic systems, the DJSF1352-RN-6 series stands out with its high-precision measurement performance of 0.5%. It supports dual-channel DC input, and can be equipped with optional analog output and wireless module expansion functions.

Built with multi-protocol communication interfaces, it can accurately capture energy data in high-voltage scenarios, providing reliable guarantee for the safe and efficient operation of energy storage systems. UL certification for this series is currently in progress.

High-Current DC Type: DJSF1352-D

To meet the high-current measurement requirements of DC charging piles, Acrel has launched the DJSF1352-D series, available in two specifications: 360A and 600A. It supports direct high-current connection measurement without additional accessories, effectively reducing operation costs.

Designed with a wide temperature resistance range, the product can operate stably in environments ranging from -40℃ to +70℃. It integrates multiple communication protocols, adapting to the harsh operating conditions of charging piles, especially ultra-fast charging scenarios.

Panel-Mounted Integrated Type: PZ96L-DE

Targeting the integration demands of energy storage systems, photovoltaic systems and DC power distribution systems, Acrel has introduced a panel-mounted DC energy meter. Supporting panel installation, it can be directly embedded into energy storage cabinets to save installation space.

The product can be optionally equipped with ±12V voltage output to meet the power supply needs of Hall sensors. The 96-format model supports 1500V high-voltage measurement and is integrated with rich communication protocols, satisfying the diversified demands of system integration.

Photovoltaic Combiner Monitoring: AGF-MT

In centralized photovoltaic scenarios, the AGF-MT photovoltaic combiner monitoring product demonstrates unique advantages. Adopting a through-type current connection method, it supports 30A current measurement, featuring convenient installation and high safety.

By optimizing the system structure and reducing wiring from photovoltaic cell arrays to inverters, it improves system stability and provides accurate monitoring support for the efficient operation of photovoltaic combiner boxes, making it suitable for 1500V centralized photovoltaic systems.

5. Supporting Sensor Solutions

To further ensure measurement accuracy and safety, Acrel’s DC meter solution is equipped with shunts and Hall sensors to meet the measurement needs of different scenarios.

Shunts

Shunts are based on the simple resistance principle, with the advantages of high cost-effectiveness, high measurement accuracy, fast response and stable performance at wide temperatures. They are suitable for cost-sensitive and high-precision measurement scenarios such as charging piles.

The specifications are flexibly selectable, such as the 500A/75mV model, which can achieve accurate measurement when matched with instrument settings. It should be noted that shunts have certain heat loss and voltage drop issues.

Hall Sensors

Hall sensors adopt a non-contact measurement method, requiring no direct connection to the circuit and no energy loss. They are suitable for high-current measurement scenarios, with high temperature resistance, flexible and safe installation.

Specifications cover 200A/5V, 500A/5V and other models, which can be seamlessly adapted to Acrel DC meters. However, their sensitivity is relatively low in low-current scenarios, and the cost is higher.

Meanwhile, a panel-mounted integrated installation solution is provided for scenarios such as photovoltaic combiner boxes, realizing plug-and-play deployment and greatly improving construction efficiency.

6. Conclusion

In the field of DC energy measurement, Acrel is becoming the preferred choice for more and more customers by virtue of its full-scenario product matrix, high-precision measurement technology and flexible supporting solutions.

Whether you are a charging pile operator, a photovoltaic system integrator or an energy storage project developer, Acrel can provide you with accurate, reliable and efficient DC energy measurement solutions.
