High-Density C&I Energy Storage Solution
As global industries transition to sustainable energy, the demand for reliable and high-efficiency Commercial & Industrial (C&I) energy storage has never been higher. The ProeM315 Series Liquid Cooling BESS represents the next generation of energy management, specifically engineered to deliver superior thermal stability, safety, and energy density in a compact outdoor footprint.
Optimized Performance with Advanced Liquid Cooling
Unlike traditional air-cooled systems, our Liquid Cooling BESS utilizes a precision-engineered thermal management system. By maintaining a uniform temperature across all battery cells, the ProeM315 series significantly reduces the risk of hotspots, extends the battery cycle life, and enhances overall system efficiency. Designed for a charging and discharging rate of ≤0.5P, this cabinet ensures stable power delivery for peak shaving, load shifting, and microgrid applications.
Uncompromising Safety & Protection
Safety is the cornerstone of our outdoor energy storage cabinet design. The ProeM315 is equipped with a multi-level fire safety system, integrating:
- Aerosol & Combustible Gas Detection for early warning.
- Active Ventilation to prevent gas accumulation.
- Water Extinguishing System as a final safety layer.
With an IP55 ingress protection rating and C4-M anti-corrosion grade, this system is built to withstand harsh environments, from coastal regions with high humidity to high-altitude installations up to 4000 meters.

Liquid Thermal Management for Enhanced ROI
Thermal consistency is the "secret sauce" of battery longevity. In a standard air-cooled cabinet, temperature gradients between cells can exceed 5°C to 10°C, leading to uneven aging and premature capacity fade. Our liquid cooling plates are engineered to maintain cell-to-cell temperature differentials within a strict ±2°C range. By ensuring every cell operates in its "sweet spot."
Furthermore, this liquid-cooled architecture reduces the system's internal auxiliary power consumption. Traditional fans consume significant energy and pull in outside dust and humidity; our sealed liquid system operates with minimal noise and maximum efficiency, even in extreme ambient temperatures ranging from -20°C to 55°C. For C&I users, this translates to more usable energy delivered over the life of the project and a much faster return on investment.
FAQ
Q: What is the expected Round-Trip Efficiency (RTE) of this liquid-cooled system?
A: Thanks to our precise thermal management and low internal resistance of the cells, the system achieves a DC-side RTE of ≥95%. The liquid cooling significantly reduces auxiliary power consumption compared to air-cooled fans in high-temperature environments.
Q: Is the system compatible with mainstream PCS (Power Conversion System) brands?
A: Yes. The ProeM315 series utilizes **Modbus TCP/CAN communication protocols, making it fully compatible with Tier-1 PCS brands like SMA, Sungrow, Growatt, and Kehua. We provide a pre-configured communication map for seamless integration.
Q: What is the C4-M anti-corrosion rating, and is it suitable for coastal projects?
A: C4-M (High) refers to ISO 12944 standards for industrial and coastal atmospheres. With a high-durability powder coating and stainless steel fasteners, our cabinet can withstand salt-mist environments for 15+ years without structural degradation.
Q: What is the maintenance cycle for the liquid cooling system?
A: The system is virtually maintenance-free. We recommend a simple visual inspection of the coolant level and a pressure check once every 24 months. The coolant itself typically has a service life of 5 to 8 years.
Q: Can I monitor the health of individual cells remotely?
A: Absolutely. Our BMS provides real-time data for every cell (Voltage, Temperature). This data is accessible via the cloud or a local LAN, allowing for predictive maintenance and remote troubleshooting.
