| Core Advantages: 1. Split heat load design delivers better cell temperature uniformity under high-temperature conditions 2. Single cooling component failure only affects 10% of total capacity, with extreme system redundancy 3. Compact single-cabinet size ensures good ventilation, minimal heat accumulation and fast hot air dissipation |
Core Advantages: 1. Factory pre-integrated design only requires single on-site cable connection, enabling the fastest construction 2. Directly applicable for ocean freight, with convenient dangerous goods declaration, customs clearance and shipping 3. Single integrated fire, monitoring and temperature control system for extremely simple O&M |
| Key Disadvantages: 1.Heavy on-site commissioning for parallel BMS/PCS cluster, with tedious circulating current and voltage equalization debugging, poses high requirements for later matainence 2. Doubled quantity of foundations, cables, busbar cabinets and fire points, leading to higher EPC costs |
Key Disadvantages: 1.Large enclosed containers have mild heat accumulation, causing slight cell temperature deviation and marginally lower cycle durability. 2.Centralized cooling design lacks redundancy; fan or AC failure will shut down the entire system. |

People May Ask
Q1. Will parallel installation of multiple cabinets lead to heat overload?
No, parallel installation won’t result in heat overload if installed per guidelines. Each cabinet has an independent air intake and exhaust system. With the recommended gap reserved between units, hot air can dissipate freely without recirculation. Besides, the built-in intelligent fan speed regulation and over-temperature derating protection further secure stable operation under multi-unit parallel full-load working conditions.
Q2. Air cooling vs Liquid cooling, which one is better for our 224kWh 80-125kW solar energy storage system?
1) Cost: Air cooling has lower cost than liquid cooling. Liquid cooling costs much more on equipment, coolant replacement and pump power, with poor ROI for this small capacity.
2) Maintenance: Air cooling needs simple filter and fan checks by local common technicians. Liquid cooling carries pipe leakage risks and demands professional trained engineers for complex periodic upkeep.
3) Project Suitability: Air cooling is well-suited for standard C&I scenarios. Liquid cooling excels in extreme high-temperature climates, 24/7 full-load operation and large MW-scale energy storage projects
Q3. How does the cabinet resist salt mist and humidity in coastal outdoor installation?
The cabinet features galvanized steel housing with anti-salt fog epoxy coating and stainless steel fasteners for exterior corrosion resistance. It has IP54 sealed structure with EPDM gaskets to block humid salt mist. Internal PTC dehumidifiers prevent condensation, while multi-layer inlet filters trap sea salt particles. All circuit boards are covered with three-proof coating, ensuring long-term reliable operation in coastal high-humidity environments.
Q4. Does the system support seamless backup power for heavy factory loads?
Yes, it fully supports seamless backup for heavy factory loads. The 80–125kW hybrid inverter realizes millisecond-level grid-to-off-grid switching with no power outage. It has strong overload capability to handle large starting inrush current of inductive equipment like motors and compressors, and maintains steady voltage & frequency under variable load conditions. In addition, it can synchronize with diesel generators to build a reliable hybrid emergency power microgrid.
