Product Introduction
C&I BESS Cabinet is a fully integrated battery energy storage solution built for commercial and industrial energy storage applications. It integrates LiFePO4 battery modules, BMS, bidirectional PCS converter, EMS controller, thermal management hardware and fire protection devices in a single cabinet. Each unit is pre-assembled and thoroughly tested before delivery. It is widely deployed for factory peak shaving and valley filling, rooftop PV paired storage, critical load backup, microgrid operation and grid demand response. The system helps industrial and commercial facility operators reduce electricity expenditure, avoid high peak power charges and secure stable power supply for core production equipment. With streamlined site commissioning, it reduces engineering workload and technical risks for EPC teams and system integrators.
Product Advantages
Stepwise Capacity Expansion Matches Business Growth
Multiple BESS cabinets can be paralleled to raise the overall power and energy capacity of the storage system. Facility owners can start with a smaller capacity matching current power consumption, and add extra cabinets when production and electricity demand grow. This approach prevents excessive upfront capital investment and avoids idle storage assets. Project Case: One manufacturing plant first deployed two 50kW/107kWh BESS cabinets to carry out peak shaving and reduce high peak electricity bills. Two years later, the plant expanded its workshop and power load, and added three more cabinets into the existing system. The original storage hardware remains fully compatible, and no replacement of core equipment is required, optimizing the capital budget of the energy storage project.
Long-cycle LiFePO4 Battery for Continuous Cyclic Use
The cabinet adopts LiFePO4 battery modules optimized for cyclic energy storage, supporting more than 6000 deep charge and discharge cycles. It maintains low capacity attenuation under repeated daily peak-shaving cycling, making it suitable for long-term continuous operation in commercial and industrial energy storage projects. Project Case: For industrial park peak-valley arbitrage and 24-hour off-grid microgrid projects, ordinary lithium energy storage batteries often suffer obvious capacity decline after 4 to 5 years of operation. Our BESS cabinet retains over 70% SOH after 6000 cycles and runs reliably for over 10 years, lowering the frequency of battery replacement and the total asset lifecycle cost for project owners.
Adaptive Energy Scheduling for Diverse Operational Goals
The built-in EMS platform supports peak shaving & valley filling, emergency backup power, PV self-consumption, off-grid microgrid and demand response modes. It collects real-time grid tariff and load data, then automatically adjusts charging and discharging strategies to match operational targets. Project Case: A shopping mall adopted this BESS cabinet for dual-purpose operation. Under normal grid conditions, the system runs peak-valley arbitrage to cut electricity costs. When grid failure occurs, it automatically switches to off-grid backup mode to sustain power for elevators, security equipment and lighting, protecting key commercial loads from blackout losses.
Hierarchical Safety Design with Active Fire Suppression
The system is equipped with cell-level BMS protection, PCS electrical protection, continuous temperature monitoring and built-in fire suppression devices. It tracks cell voltage, cell temperature and cabinet internal environment continuously, and triggers warning signals and protective actions once abnormal conditions are detected. Project Case: It has passed comprehensive safety verification for high-standard scenarios including chemical factories and food processing facilities. If local overheating risk develops inside the cabinet, the system sends remote alerts and activates fire suppression automatically, meeting local safety inspection standards and EPC acceptance requirements.
Application Scenarios
Factory Peak Shaving & Valley Filling: Store low-cost off-peak power and discharge during high-price peak hours, reduce demand charges and monthly electricity expenditure.
Rooftop PV + Energy Storage: Improve solar self-consumption rate, ease grid curtailment and make full use of on-site photovoltaic generation.
Critical Load Emergency Backup: Deliver uninterrupted power for production lines, servers and control systems to avoid heavy economic losses caused by sudden power outages.
Commercial Park / Shopping Mall: Balance power consumption profiles and provide backup power for elevators, lighting and security systems.
Off-grid Microgrid & Remote Industrial Sites: Work alongside PV arrays and diesel generators to build reliable independent power supply for mines and remote processing facilities.
Demand Response & Grid Auxiliary Service: Participate in utility demand response programs and create extra revenue for commercial and industrial power users.
