Overview

The LR series is a 51.2V rack-mounted LiFePO4 battery for system integrators, telecom and server racks — 5.12 and 11.78 kWh modules that also mount on the wall where rack space is short.

RS232/RS485/CAN communication, user-changeable inverter protocols and support for up to 15 modules in parallel make the LR a flexible building block for storage projects. An LCD display shows status at a glance; models without display are available.
