Global energy transformation is accelerating. In 2026, the share of renewable energy generation continues to rise, with new installed capacity of solar and wind power reaching record highs again. Energy storage system installations maintain rapid growth, and smart grid construction is being rolled out across all major economies. In this energy revolution, current monitoring has evolved from an auxiliary function to a core requirement – it is not only the basis for equipment protection, but also the data foundation for system optimisation and intelligent decision-making.
The digitalisation and intelligent transformation of power systems place higher demands on current sensing technology. Traditional current transformers are bulky and complex to install, making it difficult to meet the flexible deployment needs of distributed energy systems. A more flexible, more efficient, and more accurate solution is becoming the market mainstream – the Split Core Current Sensor.
Trend 1: PV + Energy Storage Boom Makes Precision Monitoring a "Must-Have"
- Solar inverters and energy storage systems are the fastest-growing segments in the new energy market.
- The role of current monitoring has been upgraded from "fault protection" to a key link in "system optimisation."
- Charge/discharge current monitoring affects battery life and peak-valley arbitrage returns. Insufficient accuracy can cause 5%-10% annual revenue loss for energy storage systems.
- Solar farms and energy storage systems are mostly deployed in outdoor, distributed environments. Ease of installation and maintenance is a key selection factor.
- Traditional closed-core transformers require cable disconnection for installation. Retrofitting already-operating plants faces power outage losses and construction risks.
The SHINHOM Split Core Current Sensor supports direct clamp-on installation without power-off. Installation time is reduced from hours to minutes. Retrofits can be completed during normal power generation hours, achieving zero generation loss.
Trend 2: Smart Grid and Energy Management – The "Nerve Endings" of Data Collection
- Smart grids require "observability, measurability, and controllability." The prerequisite is having a dense network of high-precision sensing nodes covering the entire grid.
- Current sensors are essential in power distribution automation, load management, fault recording, three-phase balancing, and other systems.
- Power digitalisation is extending to the consumption side. Demand is growing rapidly in factory EMS, building automation, home energy displays, and other areas.The common characteristics of these scenarios: large equipment quantities, distributed installation, and high sensitivity to cost and size.
With their small size, low cost, and lightweight design, Split Core Current Sensors can be deployed at scale across various power-consuming terminals.From industrial distribution cabinets to smart homes, split-core current sensors are becoming the "sensing bridge" connecting the physical power world to the digital energy world.
Product Positioning: Low Power, Small Size, High-Precision Sensing Solution
The Shinhom Split Core Current Sensor is based on the Hall effect principle. It can accurately measure DC, AC, and complex waveform currents while providing electrical isolation. The core advantages are as follows:
| Core Advantage | Technical Description | Key Parameters / Value |
|---|---|---|
| High-Precision Core Technology | Uses high-permeability nickel steel or nanocrystalline cores with optimised magnetic circuit design for excellent linearity and sensitivity | Accuracy ≤±0.2%, suitable for wide load fluctuations in new energy systems |
| Flexible Installation | Split-core structure + secure locking hinge enables quick installation without power-off | Aperture from φ12mm to φ260mm, covering a wide current range from 5A to 5000A, adapting from fine wires to large busbars |
| Environmental Adaptability & Reliability | Epoxy resin potting for moisture and dust resistance; complies with multiple international certifications | Operating temperature -15℃ to +60℃ (wide-temperature version -40℃ to +85℃ optional) |
Future Outlook: Wider Frequency Response, Intelligent Output, System-Level Integration
- Wider Frequency Response: The proliferation of wide-bandgap semiconductors such as SiC and GaN is pushing switching frequencies from tens of kHz up to the MHz level, placing higher demands on the frequency response of current sensors. SHINHOM already has the technical capability for wide-bandwidth measurement from DC to several hundred kHz.
- Intelligent Output: Traditional analogue outputs require additional post-processing. The future trend is for sensors to integrate signal conditioning, digital processing, and communication functions, supporting bus protocols such as Modbus and CAN. SHINHOM already supports customisation of output methods and leads, and is well-positioned to evolve towards intelligent sensing nodes.
- System-Level Integration: In equipment such as PV inverters and EV charging stations, current sensors are becoming increasingly integrated with power modules and control circuits. SHINHOM's compact size and lightweight design are already aligned with this trend. We also support customisation of lead length, output interface, and mounting method, providing maximum flexibility for system integration.
Conclusion: Energy Transformation Begins with Sensing
Smart grids, solar energy storage, and energy management – these trends are already a reality. The sensing layer is the gateway that connects the physical world to the digital world. High-precision, high-reliability, and high-flexibility sensing solutions are the cornerstone for safe, efficient, and intelligent system operation.
With its split core structure, high-precision magnetic core, and flexible output customisation, the SHINHOM split core current sensor provides reliable support for current monitoring in new energy applications. Whether it is real-time monitoring of solar farms, precise control of energy storage, or data collection for smart grids, SHINHOM is committed to delivering sensing solutions you can trust.
