Designed for Flexibility & Ease

· No Drilling, No Hassle (Roller Design):

  • Weighing in at 161kg, this is a heavy-duty industrial unit. However, the integrated industrial-grade casters (rollers) allow you to easily maneuver the unit into the perfect spot—be it a garage corner, a server room, or a utility closet—without any heavy lifting or wall drilling.

    · Plug & Play Installation:
    The floor-standing design simplifies setup. Just roll it in, connect to your inverter, and you have instant energy storage. It saves time and installation costs compared to complex wall-mounted arrays.

    · Smart & Safe Operation:
    Powered by Tier-1 LiFePO4 cells, it guarantees 6000+ cycles of service life. The intelligent BMS (Battery Management System) with an LCD screen keeps you informed of voltage and capacity, while supporting CAN/RS485 communication for seamless inverter integration.

    · Strong Environmental Adaptability:
    Built to perform. With a wide operating temperature range of -20°C to 60°C, it delivers stable power even in challenging environments, ensuring reliability for varied commercial and residential applications.
