BYD B-Box Premium LVL IP20, 15.4 kWh Lithium Battery - LVL15.4

Overview

The BYD Battery-Box Premium LVL 15.4kWh is a premium lithium iron phosphate (LFP) battery module designed to pair with a compatible external inverter for residential, commercial, and industrial energy storage applications. Delivering 15.36 kWh of usable energy per module and near 100% nominal-to-usable capacity, the LVL platform provides efficient, safe, and highly scalable storage for modern power systems.

With an integrated control and communication unit (BMU), the Battery-Box Premium LVL can be expanded from a single 15.4kWh module up to 983 kWh via parallel interconnection of up to 64 batteries—making it suitable for everything from home backup to large-scale hybrid and microgrid projects.
