Overview

The BYD Battery-Box HVE is a modular high voltage lithium iron phosphate (LFP) battery for use with BYD's Power Box range of inverters. It features two different capacity modules that can be flexibly combined. Module A has a usable capacity of 6.43 kWh, while Module B has a usable capacity of 4.29 kWh. A single system can be composed of up to four modules , and up to three systems can be connected in parallel, achieving a maximum capacity of 70.74 kWh. Cobalt Free Lithium Iron Phosphate (LFP) Battery: Maximum Safety, Life Cycle, and Power One of the thinnest batteries in the world with a thickness of only 140mm Easy installation thanks to patented internal plug connection and automatic configuration Wall and floor mounting options and an IP65 rating gives maximum installation flexibility Two Distinct Modules to Cover the Complete Range of System Sizes 15 Year limited warranty

Reading the specifications

BYD Battery-Box HVE is listed with 11 published specifications from BYD, including system battery voltage of HV, nominal storage capacity of 6.4 kWh, connection of Tooless and height of 233. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For a battery, the figures that matter most are system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack, cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 and round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.

Choosing a battery: the checks that matter

The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.
Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.
Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.

Where buyers lose money

Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.
Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.

Price and availability in United Kingdom

BYD Battery-Box HVE is listed at £ 1,767 (GBP) for United Kingdom. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in United Kingdom: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports BYD locally before ordering.

BYD Battery-Box HVE — frequently asked questions

How much does BYD Battery-Box HVE cost?

BYD Battery-Box HVE is listed at £ 1,767 (GBP) for United Kingdom. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

What are the specifications of BYD Battery-Box HVE?

We hold 11 published specifications for this battery, including system battery voltage HV, nominal storage capacity 6.4 kWh, connection Tooless, height 233 and width 585. The full table is on this page, listed under model BYD-HVE-A-MODULE.

Who makes BYD Battery-Box HVE?

BYD Battery-Box HVE is a BYD product, listed under batteries with model reference BYD-HVE-A-MODULE. The BYD brand page lists the rest of its range so you can compare across the catalogue.

Is BYD Battery-Box HVE right for my system?

That depends on what it has to connect to. For a battery, check cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4, round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid and communication protocol (CAN or RS485) for talking to the inverter against the rest of your equipment before price enters the decision. Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.

Where can I buy BYD Battery-Box HVE in United Kingdom?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in United Kingdom — buying in-channel is what keeps the manufacturer's warranty valid.
