The Out-Door Air Cooled BESS All In One (120kW-215kWh) is a high-performance, integrated energy storage solution built for commercial and industrial outdoor applications. Unlike indoor systems that require separate enclosures or climate control, this unit combines a 215kWh LiFePO4 battery bank, a 120kW rated PCS (Power Conversion System), and an efficient air-cooling system into a single, weather-resistant package—ready for direct outdoor deployment.

Designed for reliability, it uses LiFePO4 battery cells (known for thermal stability and long life) with a rated capacity of 280Ah and a rated voltage of 768Vdc (voltage range: 672V~864Vdc). It supports a maximum charge/discharge current of 140A (0.5C), enabling fast energy storage and release—critical for meeting commercial peak demand.
With a protection rating of IP54, the system resists dust and splashing water, making it suitable for most outdoor climates. It also operates across a wide temperature range: discharging from -20℃ to 55℃ and charging from 0℃ to 45℃, ensuring year-round performance in regions with seasonal extremes (e.g., cold winters or hot summers).

The integrated structure eliminates the need to install separate batteries, PCS, and cooling systems. You can place the unit directly on a flat outdoor surface (e.g., beside a commercial building or solar array) and connect it to the grid or renewable sources in hours—not days. This reduces labor costs and gets your system operational faster.
With a 120kW PCS and 215kWh battery energy, the system handles the high demands of commercial spaces. It can power office buildings, retail stores, or small factories during peak hours (when electricity rates are highest) and store energy during off-peak hours (low rates) or from solar panels—cutting monthly energy bills by 20-30%.
The dedicated outdoor air-cooling system keeps the battery bank and PCS at optimal temperatures, even in hot weather (up to 55℃ for discharge). Unlike liquid-cooled systems, it requires no coolant replacement or leak checks—just occasional filter cleaning (every 3-6 months). This lowers long-term maintenance costs and reduces downtime.
The IP54 rating ensures the system is protected against dust buildup (no harmful accumulation) and splashing water (e.g., rain, sprinklers). This means no additional enclosure is needed, even in rainy or dusty environments—saving on installation costs and simplifying setup.
For offices, shopping malls, or hotels, the system performs “peak shaving”: storing energy during off-peak hours (low rates) and releasing it during peak hours (high rates). This reduces reliance on expensive grid power during peak times, slashing energy costs. It also acts as backup power for critical systems (e.g., elevators, security cameras) during short outages.
Solar plants often struggle with intermittent energy output (e.g., cloudy days or nighttime). This BESS stores excess solar energy during the day and feeds it back to the grid in the evening—boosting the plant’s energy utilization rate by 15-25% and increasing revenue from grid sales.
Hospitals, data centers, and fire stations need reliable backup power. The 215kWh capacity can power critical equipment (e.g., medical devices, servers, communication systems) for 2-4 hours during grid failures—minimizing downtime and preventing costly or life-threatening disruptions.
An IP54 rating has two key protections: 1) Dust protection: No harmful dust enters the unit (prevents component damage); 2) Water protection: Resists splashing water from any direction (handles rain, sprinklers, or accidental spills). It’s not waterproof (don’t submerge it), but it’s ideal for most outdoor settings.
Yes. The system discharges efficiently in temperatures as low as -20℃—critical for winter use in cold regions. However, charging below 0℃ is not recommended (it can damage batteries), so the system automatically pauses charging if temperatures drop below 0℃ and resumes once it warms up.
Charging time depends on input power. With a maximum charge current of 140A (0.5C) and rated voltage of 768Vdc, the charging power is ~107.5kW (768V × 140A). At this rate, the 215kWh battery fully charges in ~2 hours (215kWh ÷ 107.5kW ≈ 2h). Charging may take slightly longer in cold weather (below 10℃) as battery efficiency dips.
The system monitors itself automatically. It tracks battery temperatures and adjusts fan speed to maintain optimal conditions (0℃~45℃ for charging). If the cooling system malfunctions, the unit sends an alert via its built-in communication tools (e.g., email or app notification). You only need to clean the air filters every 3-6 months to keep it running efficiently.
