BYD B-Box Premium HVM 2.76kWh Lithium Battery - BYDHVM

Overview

STOCK EXPECTED TO ARRIVE IN NOVEMBER. The BYD Battery-Box Premium HVM is a high-voltage lithium iron phosphate (LFP) battery system designed for use with compatible external hybrid and battery inverters. Each HVM tower consists of 3 to 8 battery modules connected in series, delivering a usable capacity from 8.3 kWh to 22.1 kWh.

Up to three identical HVM towers can be connected in parallel to achieve a maximum system capacity of 66.2 kWh. The modular design allows future expansion by adding additional HVM modules or parallel towers, making it ideal for residential and small commercial applications requiring higher storage capacity, backup power, and increased energy independence.
