1. In the dual-carbon era, your electricity carbon footprint needs precise measurement.

As "carbon neutrality" becomes a global consensus, carbon management for enterprises and industrial parks has transformed from an "optional action" to a "mandatory task." Driven by the "dual-carbon" goal, carbon metering has become a crucial link in the green transformation of enterprises and industrial parks. Acrel's carbon meters, paired with the Acrel carbon asset management platform, help enterprises complete the entire closed-loop process from carbon emission accounting to carbon trading strategy formulation through digital, standardized, and refined management processes, accelerating energy conservation and emission reduction, and achieving efficient management and value mining of carbon assets.

Batteries are a core component of power supply systems such as UPS, DC power supplies, data centers, and communication base stations, serving as the "last line of defense" for power supply. However, batteries often face challenges during operation, including:

plate aging and acid drying;

overcharging, over-discharging,

abnormal temperature; and increased internal resistance leading to capacity reduction.

Residential solar PV is a small-scale photovoltaic (PV) power generation system installed on the roof, balcony, or other areas of a home to power the household itself. It can be grid-connected or paired with energy storage for off-grid emergency use, making it a mainstream solution for home energy self-sufficiency.

Demand typically refers to the average rate of electricity consumption by a user over a specific period. It is usually measured in kilowatts (kW) or megawatts (MW), representing the average power consumption level achieved by a user within a specified time period (such as 15 minutes, 30 minutes, or 1 hour, which is the demand cycle). It reflects the instantaneous demand of users on the power system.

The Acrel-EIoT Energy Internet of Things Cloud Platform is an open platform based on an IoT data middleware, establishing unified uplink and downlink data standards to provide energy IoT data services to internet users. Users only need to purchase Acrel IoT sensors, select a gateway, install them themselves, and scan a code to access the required industry data services via their mobile phones and computers.

1. Photovoltaic Storage and Backflow Prevention: Key Challenges and Core Needs in Energy Transition

(I) A Technological Necessity Driven by Both Policy and Market

Introduction: Technology barriers become business opportunities, and accurate measurement is the key

With the acceleration of global energy transition, China's charging pile enterprises are experiencing a wave of overseas expansion. The European Union, as a market with a high penetration rate of new energy vehicles, has become a key focus for many companies. However, the EU market's strict entry standards, especially the mandatory MID certification requirements for metering equipment, have created technical barriers for the export of charging piles.

System Introduction

The Acrel-2000MG Microgrid Energy Management System is a new-generation microgrid energy management solution specifically developed by our company. It was designed in response to the requirements of modern power systems and "Dual Carbon" goals, drawing upon advanced research and production expertise from both domestic and international contexts. This system enables the orderly management and optimized control of an enterprise's microgrid assets—including sources (utility grid, distributed PV, micro-wind turbines), the grid infrastructure (internal distribution network), loads (fixed and adjustable loads), energy storage systems, and EV charging loads. It facilitates flexible interaction among these "Source-Grid-Load-Storage" resources to achieve various operational objectives, thereby enhancing system stability through multi-strategy control. Furthermore, the system promotes the efficient integration of renewable energy, facilitates intelligent peak shaving and valley filling, reduces capital investment in grid infrastructure, improves corporate energy utilization efficiency, lowers operational costs, and ultimately achieves the goals of energy conservation and consumption reduction.
