Built for the C&I Sites.

Designed for backup power, peak-demand reduction, and solar integration, all housed in a compact outdoor cabinet and maintained at a consistent operating temperature by liquid cooling, even in the harshest conditions.

Liquid-Cooled Cabinet Design

Integrated liquid cooling keeps every cell within its optimal temperature range across India’s hottest operating days.

AI-Powered Energy Management

The built-in EMS reads your load patterns and automatically decides when to store, when to discharge, and when to draw.

Multi-Layer Safety Protection

Built-in protection against overcharge, over-discharge, overcurrent, and thermal events, keeping the system and the people around it safe at all times.

IP54 Cabinet Enclosure

IP54 Cabinet Enclosure

The cabinet is rated IP54 for outdoor use, with the battery pack independently rated IP65 for a higher level of protection against dust and water ingress.

Modular and Scalable by Design

Start with one cabinet and connect multiple units in parallel as your facility grows, with no redesign or reconfiguration needed.

Peak Efficiency and Performance

Continuously optimised to deliver consistent output, ensuring your system performs at its best under any load condition.
