The CFE 125H2-PV-STS is a fully integrated, high-capacity industrial energy storage system designed for demanding commercial and industrial applications. This all-in-one solution combines 125kW of output power with 261.24kWh of usable LFP battery capacity in a single compact enclosure. With dual built-in MPPT channels totaling 126kW for direct PV integration and an integrated Static Transfer Switch (STS) for seamless grid-tied and off-grid switching in less than 20 milliseconds, it delivers both cost optimization and power reliability in one platform.
Designed for outdoor installation, the system features IP54 protection and precision liquid cooling, making it suitable for factories, data centers, industrial parks, and large commercial facilities. As part of modern Industrial and Commercial Energy Storage Solutions, the CFE 125H2-PV-STS helps users reduce energy costs, improve solar self-consumption, and maintain stable operation under demanding site conditions.
The CFE 125H2-PV-STS stands out through true all-in-one integration, industrial-grade durability, and intelligent energy management.
Unlike conventional systems that require separate PV inverters and battery cabinets, this unit integrates dual 63kW MPPT trackers with the battery storage system in one enclosure. With a total PV input of 126kW and MPPT efficiency of up to 99%, the system enables intelligent energy flow management between solar PV, battery storage, site loads, and the utility grid. This integrated design simplifies installation and improves overall system coordination.
For critical applications, uninterrupted power is essential. The built-in Static Transfer Switch enables seamless switching between grid-connected and off-grid modes in less than 20 milliseconds, helping ensure that sensitive loads such as servers, communication systems, and industrial control equipment continue operating without disruption. The system also supports 110% continuous overload capability and 120% short-term output capacity.
The system integrates 125kW of power and 261.24kWh of energy storage into a single enclosure with a footprint of only 1.35m². This compact design reduces installation complexity, saves valuable site space, and minimizes interconnecting cabling compared with multi-unit system layouts. For users seeking practical Industrial and Commercial Energy Storage Solutions, this creates a strong balance between capacity and deployment efficiency.
Using 3.2V 314Ah prismatic LFP cells, the system employs precision liquid cooling to maintain optimal cell temperature and improve temperature consistency across the battery pack. This supports stable performance, extends battery life to more than 8,000 cycles, and enables reliable operation in ambient temperatures up to 55°C. For customers deploying a peak shaving battery system or solar-plus-storage solution in demanding climates, liquid cooling provides a clear performance advantage.
Safety and control are managed through a two-layer BMS architecture that provides accurate cell-level monitoring and system-level coordination. The built-in local controller works together with a cloud platform for real-time monitoring, remote diagnostics, and energy dispatch. It supports Modbus TCP/RTU protocols and can integrate with mainstream SCADA platforms, making facility-level energy management more efficient and transparent.
The CFE 125H2-PV-STS is engineered to meet the high-power demands of critical infrastructure and large-scale energy users.
With sub-20ms STS switching, the system provides highly reliable backup support for servers, network equipment, cooling systems, and other critical loads. It acts as a power buffer during grid instability and can support facility operations until backup generators start, or even replace generators in short-duration outage scenarios.
When deployed alongside large commercial solar arrays, the system stores excess solar generation and releases it during non-solar hours, increasing on-site self-consumption and reducing dependence on the grid. As a high-performance solution for Renewable Energy integration, it helps improve energy utilization and site resilience.
For factories, industrial parks, and large commercial buildings with high electricity demand, the CFE 125H2-PV-STS can operate as a highly effective peak shaving battery system. It charges during low-tariff periods or from solar generation and discharges during peak demand periods, helping reduce electricity bills and demand charges.
Its integrated design, rugged outdoor enclosure, and compact footprint also make it suitable for mobile energy storage applications and industrial microgrids in remote or weak-grid areas. This flexibility makes it a practical option from a trusted C&I Battery Storage System Supplier for projects requiring fast deployment and reliable local power support.
The CFE 125H2-PV-STS is designed, tested, and manufactured to meet demanding international standards for safety, performance, and grid compatibility.
The system carries CE certification, demonstrating compliance with European safety, health, and environmental protection requirements. It is also designed in accordance with relevant IEC standards for electrical equipment and energy storage applications.
Rated IP54 for dust and water resistance and C4 for corrosion protection according to ISO standards, the enclosure is built for long-term outdoor operation in industrial and coastal environments. The system operates reliably in ambient temperatures from -20°C to 55°C.
The system includes multiple layers of safety protection, including liquid cooling, dual airflow isolation, overcurrent protection, short-circuit protection, arc fault detection, and an integrated aerosol fire suppression system inside the enclosure. These features help ensure reliable and secure operation across demanding application scenarios.
