Liquid-cooled Hybrid Cabinet
This Commercial Energy Storage System is built around a liquid-cooled hybrid cabinet architecture, purpose-designed for demanding commercial and industrial (C&I) energy storage projects. By integrating the battery system, hybrid inverter, PV input, EMS and thermal management into a single, factory-tested cabinet, it reduces system interfaces and minimizes on-site integration risks.
The system supports 75kW to 125kW output power with up to 261kWh energy capacity, delivering high power density in a compact footprint. Advanced liquid cooling ensures stable operation under continuous load and high ambient temperatures, making it particularly suitable for applications such as peak shaving, PV self-consumption optimization, backup power and grid interaction. For EPC contractors, system integrators and project developers, this translates into faster deployment, predictable performance and a scalable solution optimized for long-term commercial operation.
Enhanced Hybrid Inverter Integration
Compared with conventional commercial energy storage systems that focus on a simple combination of battery and PCS, this solution is designed with a stronger emphasis on hybrid inverter integration. The system supports PV, grid and battery operation within a single platform, allowing energy to be managed dynamically according to on-site load profiles and grid conditions.
The built-in hybrid inverter architecture, combined with multiple MPPT channels and a wide PV voltage range, enables flexible PV array configurations and improves overall solar energy utilization. This makes the system adaptable to different commercial and industrial system topologies, whether it is a PV-first self-consumption model, peak shaving with grid interaction, or hybrid operation with backup requirements.

Advanced Liquid Cooling System
Thermal management is one of the most critical factors affecting the performance and lifespan of a commercial energy storage system. This cabinet adopts a liquid cooling system combined with forced air cooling, specifically designed for high-power, long-duration C&I applications.
The optimized cooling design allows the system to operate reliably under high ambient temperatures and continuous load conditions, making it suitable for industrial environments where thermal challenges are common. Even during peak charging and discharging periods, the battery system remains within a safe and efficient operating range.
- For EPC contractors and project owners, this means:
- Longer battery cycle life
- Reduced performance degradation over time
- Lower maintenance frequency and operating risk
- Improved system availability for revenue-generating applications such as peak shaving and demand response
By integrating liquid cooling at the system level, this commercial energy storage system delivers higher reliability, predictable performance, and lower total cost of ownership across the full project lifecycle.
High-Integration Liquid-Cooled Hybrid Architecture
Unlike conventional commercial energy storage systems that rely on separated PCS and battery cabinets, this solution adopts a high-integration liquid-cooled hybrid architecture, combining battery system, hybrid inverter, PV input, EMS and thermal management into a single cabinet. This design significantly reduces system complexity and on-site engineering workload, which is a key concern for EPC contractors and project owners.
By integrating liquid cooling with forced air cooling, the system maintains a stable operating temperature and limits cell temperature deviation to within 3°C, even under continuous high-power operation. This directly improves battery consistency, extends cycle life and enhances long-term system reliability. At the same time, the wide PV input range and multi-MPPT design allow flexible PV array configurations, enabling efficient utilization of solar generation in commercial projects.
Compared with traditional air-cooled or modular battery systems, this Commercial energy storage system delivers higher energy density, simpler installation and more predictable performance across the full project lifecycle, making it particularly suitable for demanding commercial and industrial applications where reliability, integration level and total cost of ownership are critical.
