Safety is paramount in highly flammable environments. The KRL-B261L introduces a true "Zero-Accident" architecture. Its advanced liquid cooling limits battery temperature differences to within 3℃, completely eliminating thermal runaway risks. Furthermore, its <10ms UPS-grade switching seamlessly replaces diesel generators, keeping pumps and payment systems running safely during outages.

Disaster emergency power supply

Disaster emergency power supply

In disaster zones with extreme temperatures or heavy airborne debris, air-cooled units might clog or overheat. The KRL-B261L’s liquid-cooled system operates flawlessly regardless of external air quality, providing instant, life-saving electricity for rescue command centers and medical equipment with absolute reliability and rapid deployment.

Factory power supply

Factory power supply

Heavy manufacturing plants and data centers cannot afford a single millisecond of downtime. The KRL-B261L protects expensive machinery from voltage drops with its sub-10ms transfer time. Crucially, the precise liquid temperature control significantly extends the battery lifecycle, maximizing the long-term ROI for industrial peak-shaving and continuous backup power.

Supermarket Power Supply

Supermarket Power Supply

Protect perishable inventory and ensure continuous retail operations even in scorching summer heat. Because the KRL-B261L is liquid-cooled, it operates ultra-quietly and can be safely installed in outdoor supermarket parking lots directly exposed to the sun. It utilizes rooftop solar to slash daily electricity bills while maintaining a comfortable shopping environment.

PV power generation

PV power generation

Large-scale solar farms are often located in blistering desert climates. The KRL-B261L is the ultimate energy vault for these extreme setups. Its aerospace-grade thermal management ensures the batteries remain at an optimal operating temperature despite extreme external heat, efficiently storing surplus daytime solar energy and maximizing your solar investment.

Engineered for extreme environments and uncompromising safety, the flagship KRL-B261L 125kW/261kWh Liquid-Cooled All-in-One ESS is designed to conquer the most demanding global power challenges.
