Acrel Solution Introduction

Acrel Co., Ltd. was established in 2003 and listed in 2012 with the stock code 300286. The company's headquarters is located in Shanghai with a production base in Jiangyin, Jiangsu. Provide comprehensive energy efficiency system solutions from system software to hardware, helping users achieve reliable, safe, and efficient energy use goals. The company's annual turnover is 180 million USD, 12% of annual sales revenue is invested in R&D. Acrel has 2,000 staff, including 450 R&D personnel.  In 2023, annual output reached 5 million units, and currently, 40,000 sets of energy efficiency systems are operating in various places.

The products have been successfully applied in projects such as the Kenya Telecom Tower Power Monitoring Project, the Tesla SH Factory Energy Management System Project, the Hong Kong Green School Energy Consumption System Project, the South Africa Apartment Electricity Prepaid Project, the CISCO USA Energy Management System Project, and more.

Acrel EMS 2.0 Energy Efficiency Management Platform monitors and analyzes the power, grid, load, energy storage, and charging. Realize the data interaction among each system. Improve energy efficiency, lower user cost, and achieve carbon peaking and carbon neutrality.

This Acrel EMS 3.0 Smart Energy Management System can dispatch and manage power, grid, load, energy storage, and charging. To lower the cost, improve the renewable energy usage efficiency, benefit from multi-tariff electricity price, demand management, and VPP transaction

This diagram illustrates the solutions Acrel can provide for new energy, from hardware to software.

From left to right, the first section shows distributed photovoltaics. We offer the AGF current collection device. The gateway collects inverter data, including AC and DC side data, and uploads it to the platform. It supports most inverter brands on the market, including Huawei, Sungrow, and Growatt. On the grid-connected side, we provide anti-islanding protection and power quality monitoring. This can be discussed with customers based on local policies, such as whether there are anti-islanding policies and whether the grid has power quality requirements for grid connection.

The second section focuses on distributed energy storage. The first example is the ACREL-2000ES energy storage cabinet energy management system, which offers comprehensive energy storage monitoring and management capabilities. It can monitor detailed information on the PCS, BMS, electricity meters, fire protection, air conditioning, and more. It implements data collection and processing, visual monitoring, alarm management, and statistical reporting. It supports energy scheduling and features control functions such as planning curves, peak shaving, and valley shifting, demand control, and backup power. It can be used in both integrated energy storage cabinets and energy storage containers. We also offer DC meters (UL, MID), Hall effect sensors, and insulation monitoring devices for industrial energy storage. Grid-connected testing also includes anti-islanding and power quality analysis.

The third section focuses on residential solar-plus-storage systems, primarily featuring two UL/MID meters with reverse current protection. The AGF-AE-D is designed for single-phase, three-wire systems in America. These meters can also be connected to a platform system for monitoring and management via the IoT, and can be integrated with inverters and PCSs to implement reverse current protection.

The fourth section showcases DC power distribution systems, which are not very common currently but are expected to be a future trend. (If interested, you can discuss why DC power distribution systems are a trend, integrating them with new energy distributed power sources, power supply for electrical equipment, and equipment lifespan, demonstrating your expertise.) We also provide DC meters, Hall effect sensors, insulation monitoring devices, gateways, platforms, and more.

The fifth section focuses on charging stations. This is divided into two areas: Ankerui manufactures charging piles, including AC and DC models, single-pole and dual-pole DC charging stations, and charging stacks. Currently, we primarily promote European-standard AC charging piles overseas, which are CE-certified and support OCPP protocol integration. We also provide supporting charging pile equipment, including AC and DC meters and insulation monitoring.

Finally, let me introduce our 2000MG energy management system. It supports the integration of photovoltaic systems, energy storage systems, and other equipment for monitoring and energy management. This system achieves economically optimized operation while maintaining safety and stability, improving the absorption of new energy, shaving peaks and shifting valleys, managing demand, smoothing loads, and reducing power supply costs.

This panel shows the Acrel Energy Efficiency Management System.

Acrel offers complete energy efficiency management solutions. Includes from the user substation, to the low-voltage inlet line, to the low-voltage distribution, and then to various specific end equipment electricity monitoring, and can support access to water meters/gas meters/heat meters, etc., to help enterprises to carry out the construction of three-level energy metering system, find out the source of low energy efficiency, to achieve full coverage of enterprise energy efficiency monitoring.

The system consists of three parts: perception layer (energy metering terminal), network layer (communication management terminal), and platform layer (enterprise energy management and control platform). The Acrel product models are very rich and can meet the needs of different scenarios. At the same time, we can provide products with CE/MID/UL certification.

It can be used in schools, hospitals, factories, shopping malls, logistics centers, etc

The ACREL power monitoring SCADA system is mainly used in 35kV or 10kV substations and power distribution rooms, providing reliable and safe system solutions for users.
