Overview
The BYD Battery-Box HVS+ and HVM+ are modular high voltage lithium iron phosphate (LFP) battery packs for use with an external inverter. Battery-Box HVS+ One Battery-Box HVS+ is composed of 2 to 5 HVS battery modules, together with a BCU and Base, that are connected in series to achieve a usable capacity of 5.1 to 12.8 kWh*. Additionally, direct parallel connection of up to 3 identical Battery-Box HVS+ allows a maximum capacity of 38.4 kWh*. Battery-Box HVM+ One Battery-Box HVM+ is composed of 3 to 8 HVM battery modules, together with a BCU and Base, that are connected in series to achieve a usable capacity of 8.3 to 22.1 kWh*. Additionally, direct parallel connection of up to 3 identical Battery-Box HVM+ allows a maximum capacity of 66.2 kWh*. Capable of High-Powered Emergency-Backup and Off-Grid Functionality Highest Efficiency Thanks to a Real High-Voltage Series Connection The Patented Modular Plug Design Requires no Internal Wiring and Allows for Maximum Flexibility and Ease of Use Cobalt Free Lithium Iron Phosphate (LFP) Battery: Maximum Safety, Life Cycle, and Power Compatible with Leading 1 and 3 Phase High Voltage Battery Inverters Two Distinct Modules to Cover the Complete Range of System Sizes Highest Safety Standards like VDE 2510-50 IP55 Operating temperatures between -10°C to +50°C. Power derating will occur between -10°C and +5°C.

How to read this datasheet
BYD Battery-Box HVS+/HVM+ is listed with 11 published specifications from BYD, including system battery voltage of HV, nominal storage capacity of 2.56 kWh, connection of Tooless and height of 240. 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 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, 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. 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.
Before you buy a battery
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.
- 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.
- Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
What people get wrong
- Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
- 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.
Price and availability
BYD Battery-Box HVS+/HVM+ is listed at £ 805 (GBP). 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 your country: 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 HVS+/HVM+ — frequently asked questions
How much does BYD Battery-Box HVS+/HVM+ cost?
BYD Battery-Box HVS+/HVM+ is listed at £ 805 (GBP). 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 HVS+/HVM+?
We hold 11 published specifications for this battery, including system battery voltage HV, nominal storage capacity 2.56 kWh, connection Tooless, height 240 and width 610. The full table is on this page, listed under model BYD-HVS-PLUS-MODULE.
Who makes BYD Battery-Box HVS+/HVM+?
BYD Battery-Box HVS+/HVM+ is a BYD product, listed under batteries with model reference BYD-HVS-PLUS-MODULE. The BYD brand page lists the rest of its range so you can compare across the catalogue.
Is BYD Battery-Box HVS+/HVM+ 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. Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
Where can I buy BYD Battery-Box HVS+/HVM+?
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 — buying in-channel is what keeps the manufacturer's warranty valid.
