    Photovoltaic-energy Storage Integration

    The system monitors local load power in real time, prioritizes self-consumption of solar generation with surplus stored in batteries, and uses battery storage first when solar power is insufficient.

  • 02

    Space Saving

    It features a door-mounted integrated air conditioner that saves internal space, increases usable capacity for outdoor cabinets, and ensures better structural integrity and waterproof performance.

  • 03

    Easy Installation

    The PCS and battery system integration is completed before shipping, significantly reducing the on-site wiring and joint commissioning costs overseas (in the traditional model, the inverter and battery manufacturers need to install separately).

  • 04

    Flexible Expansion

    With patented virtual synchronous machine technology, the system enables long-distance parallel operation without communication lines and supports seamless grid-to-off-grid switching.

  • 05

    Long Lifecycle Compatibility

    Designed to meet global market demands for full lifecycle reliability, our BESS integrates appearance, structure, and interface to ensure deep compatibility with battery cells’ 10-year warranty cycle (up to 10,000 cycles).

  • 06

    Intelligent Management

    Real-time liquid leakage monitoring reduces on-site maintenance, while local control and cloud platform management with intelligent equalization and instant system alerts ensure battery consistency throughout its entire life cycle.

  • 07

    High Efficiency and Safety

    The intelligent liquid cooling temperature control system minimizes cell temperature differences within the battery pack, ensures consistent thermal management, extends battery life, and reduces overall energy consumption.

What is a C&I battery energy storage system?
Commercial and industrial (C&I) battery storage systems are designed specifically for industrial and commercial applications. Featuring a modular design, they offer flexible voltage and capacity configurations to meet diverse energy demands. These systems help reduce electricity costs by managing peak and off-peak usage, while also serving as backup power during outages. Additionally, C&I renewable energy storage supports grid stability, enables participation in electricity spot markets, and provides ancillary services.
How does a battery energy storage system work?
Commercial and industrial energy storage systems store and distribute electricity through battery charging/discharging, energy management, and power conversion. They help lower electricity costs, improve energy efficiency, and enhance power supply stability.
What is the cost of battery energy storage systems?
The cost of C&I energy storage solutions varies due to factors such as EPC costs and system equipment costs, including battery cells, PCS, BMS, EMS, cabinet, fire protection, and electrical components. Key cost drivers include system scale—larger systems (10MWh+) benefit from lower unit prices—and regional differences, as land and labor costs in major cities can increase total costs by 10–20%. Despite these variations, energy storage offers strong ROI through peak-valley arbitrage (a 2MWh system typically sees a 2–3 year payback) and electricity savings via peak shaving and load shifting.
