BYD B-Box Premium HVS 2.56kWh Lithium Battery - BYDHVS

Overview

ONLY 1 LEFT AT THIS PRICE. The BYD Battery-Box Premium HVS is a high-voltage lithium iron phosphate (LFP) battery system designed for use with compatible external hybrid and battery inverters. Each HVS tower consists of 2 to 5 battery modules connected in series, delivering a usable capacity from 5.1 kWh to 12.8 kWh.

Up to three identical HVS towers can be connected in parallel to achieve a maximum system capacity of 38.4 kWh. The modular design allows future expansion by adding additional HVS modules or parallel towers, making it suitable for residential and small commercial applications seeking high efficiency, backup power, and increased energy independence.
