BYD Battery-Box HVM+ 2.76 kWh | Single Module for Retrofitting

Battery-Box HVM+ Battery Module for Retrofitting

Scope of Delivery
1x battery module

New Features at a Glance

The Battery-Box Premium HVM+ (High Voltage Medium storage) is the latest generation of BYD battery storage systems and, compared to its predecessor, not only offers all previous functions but also enables trouble-free expansion without having to adjust the state of charge beforehand. This is made possible by the new and improved Battery Management System, which handles the SoC matching.
In addition, clear, modular network connectivity including app-based commissioning and remote updates is now possible thanks to the included WiFi/LAN module.
The new battery storage system also has protection class IP55.
This means the BYD B-Box Premium HVM+ can also be installed in a sheltered outdoor area.

Flexible and Scalable

Since the BYD battery has a modular design, the storage system can be expanded later in 2.76 kWh increments.
Unlike the predecessor model, no prior adjustment of the individual batteries' states of charge is required here.
Expansion is now done via simple plug-and-play with a new battery module.

You can still connect up to 3 battery towers into one system. Each battery is also able to deliver its rated capacity as power output.
Please note that the HVM+ complete storage systems are not compatible with the existing HVM system.

The BYD B-Box Premium HVM+ is compatible with, among others, the popular Kostal Plenticore inverters as well as Solis S6 inverters.
A detailed compatibility list can be found under the "Downloads" tab.

Advantages

• Automatic balancing of states of charge during initial installation and storage expansion
• Highest safety standards such as VDE 2510-50
• Compatible with leading inverter manufacturers
• Cobalt-free lithium iron phosphate battery (LFP): maximum safety,　lifespan and performance
• The patented modular plug-in design requires no internal wiring and enables maximum flexibility and ease of use

Further Innovations in the BYD Battery-Box Premium HVM+

• Significantly higher and longer peak output:
  The HVM+ now delivers 80 A for 15 seconds (previously 75 A for 3 seconds), which better absorbs load peaks in larger systems and three-phase inverters. Continuous current remains at 50 A.
• Adjusted voltage window:
  The upper voltage limit is around 2–4% lower depending on capacity (e.g. HVM+ 22.1 kWh: 320–460.8 V instead of 320–472 V).
• Changed dimensions and weight:
  The new modules are wider (610 mm instead of 585 mm) and flatter (282 mm instead of 298 mm) as well as heavier (41.4 kg instead of 35-38 kg). Complete towers weigh 20 to 50 kg more depending on size, which should be taken into account for mounting and load-bearing capacity.
• Unchanged proven features:
  Capacities from 3–8 modules (8.3–22.1 kWh), lithium iron phosphate technology (LFP), protection class IP55, temperature range from -10 to +50 °C, CAN and RS485 interfaces, as well as a 10-year warranty with at least 60% remaining capacity.
