Rackwall 15 | LIO 15.0-IP20 Lithium-ion Battery

14.3kWh High-Capacity Rack-Mounted LiFePO₄ Energy Storage
The Rackwall LIO 15.0-IP20 is a powerful rack-mounted lithium iron phosphate (LiFePO₄) battery designed for residential, commercial, and industrial energy storage systems. With a total energy capacity of 14.3kWh (51.2V, 280Ah), it provides long-lasting reliability, scalability, and superior performance for both hybrid and off-grid applications.

Built with A-grade prismatic LiFePO₄ cells, the Rackwall 15 ensures over 6000 cycles at 90% DoD, offering extended service life, excellent thermal stability, and 10+ years of calendar life. Its smart Battery Management System (BMS) includes full protection against overvoltage, undervoltage, overcurrent, temperature extremes, and short circuits, ensuring safe and efficient operation.

The system features a 4.3-inch touchscreen LCD for real-time monitoring, along with RS485 and CAN communication for seamless integration with leading inverters. Designed for modularity, it supports parallel expansion of up to 15 units, delivering scalable energy storage solutions for larger setups.

Housed in a 19” standard rack-mount enclosure with quick-release terminals, the LIO 15.0-IP20 is easy to install, maintenance-free, and optimized for long-term use in demanding environments.
