KRL-B261 Applications & Solutions

Mountainous areas and islands
Establishing true energy independence requires equipment that defies unpredictable weather. The IP65-rated completely sealed cabinet of the KRL-B261L effortlessly resists salt spray, high humidity, and dust on islands or mountains. Paired with its massive 120kW MPPT, it rapidly captures solar energy to build a self-sustaining micro-grid without relying on expensive diesel transport.

Gas station
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
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
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
