Upgrading Energy Monitoring Architecture for DC Microgrids
Acrel Co., Ltd. (300286.SZ) has been officially awarded a new design patent by the China National Intellectual Property Administration for its latest hardware component, the “DC Power Meter (DJSF1352-D-360)” (Patent No. CN202530640837.1). The patent, formally granted on June 16, 2026, highlights the company’s continuous engineering refinements in industrial enclosure design and space optimization for electrical panels.
This specialized DC energy meter is engineered to address critical telemetry demands in modern power distribution systems. The device provides precise tracking of multiple electrical parameters across DC networks, including:
- Real-time DC voltage and current monitoring
- Bi-directional energy measurement (forward and reverse active energy tracking)
- Dynamic power consumption calculations
- Onsite ambient and component temperature sensing
Direct Applications: EV Charging Stations, Data Centers, and Solar PV
As global industries shift toward low-carbon infrastructure, the deployment of robust DC metering hardware has become vital. The DJSF1352-D-360 smart energy meter is purposefully built to integrate with high-growth downstream setups:
- EV Fast-Charging Infrastructure: Ensuring highly accurate billing and power allocation metrics for high-voltage DC fast-charging stations.
- Solar PV and Energy Storage Systems (ESS): Tracking power generation and battery discharge vectors within local hybrid microgrids.
- Telecom Base Stations & Data Centers: Monitoring energy efficiency profiles across DC-powered server racks and critical backup power systems.
Financial Resilience and Steady R&D Execution
The acquisition of this design patent marks Acrel’s 21st newly authorized patent since the start of 2026, underlining a consistent operational rhythm in product development.
This steady rollout of advanced hardware is heavily supported by strategic capital allocation. Acrel’s 2025 financial disclosures reveal a total R&D expenditure of RMB 119 million, reflecting a 1.93% year-on-year increase. This consistent investment ensures that Acrel’s full commercial suite—including power quality analyzers, active harmonic filters (AHF), and wireless energy monitors—maintains a competitive edge in manufacturing quality and field reliability.
By upgrading the physical profile and monitoring capabilities of its DC power meters, Acrel continues to provide global engineers with highly compact, multi-functional edge hardware that integrates seamlessly into larger Microgrid Energy Management Systems (EMS).
