Microgrid BESS Solutions

Overview

Designed for scenarios with weak grid infrastructure, high electricity costs, or extremely high requirements for power supply reliability, the solution builds a microgrid architecture based on “PV priority, energy storage regulation, utility grid support, and diesel generator backup.” The system supports off-grid/islanded operation, voltage fluctuation suppression, uninterrupted power supply for critical loads, and cloud-based intelligent operation and maintenance.

Key Benefits

Millisecond storage response with multi-energy redundancy delivers zero-perception switching, eliminating downtime and data loss. Intelligent PV-storage-grid-diesel dispatch achieves peak shaving, green power priority, and fuel savings. Cloud-edge-device architecture simplifies remote monitoring and O&M. Boosts green power self-consumption, reduces carbon intensity, and supports ESG goals—delivering reliability, cost efficiency, and sustainability in one system.

Core Business Value

  • 01

    Multi-Energy Coordination and Power Supply Assurance

    Integrates multiple energy sources, including PV, energy storage, utility power, and diesel generators, to enable intelligent coordinated control and optimized dispatching. With millisecond-level energy storage response and a multi-energy redundancy design, it ensures "zero-perception" switching for critical loads, guaranteeing business continuity and power supply reliability.

  • 02

    Intelligent Energy Management for Cost Reduction and Efficiency Improvement

    Achieves optimal overall energy costs through peak shaving and load shifting, prioritized renewable energy consumption, and coordinated optimization of diesel generator operations. Supports demand management, energy dispatching, and operational strategy optimization, significantly reducing electricity expenses and fuel consumption costs.

  • 03

    Cloud-Based O&M and Low-Carbon Sustainable Development

    Utilizes an integrated cloud-edge-device management architecture to achieve remote monitoring, fault alerts, energy efficiency analysis, and intelligent O&M. Increases the self-consumption ratio of green electricity, reduces carbon emission intensity, and supports enterprises in achieving ESG goals and building green certifications.
