BYD Battery-Box Premium HVS / HVM high voltage

BYD manufacturer of batteries for storage systems has developed a line suitable for any application. With modular high and low voltage solutions for residential, commercial and large deployments.

BYD’s cobalt-free lithium iron phosphate (LFP) battery ensures maximum safety, long life cycle and power. The product with a simple and universal design and a sturdy structure adapts to any environment and temperature.

BYD products meet the highest safety standards such as VDE 2510-50 (HVS / HVM / LVS) and have won numerous awards and recognitions in recent years including the TOP Brand PV Storage 2020 Europe.

B-Box Premium HVS / HVM high voltage batteries

The new high voltage batteries of the BYD Premium series, HVS and HVM, are devices composed of several battery modules, connected in series with each other.

They can be combined with both single-phase and three-phase inverters from different brands including Fronius, GoodWe, Kostal, SMA, SolarEdge.

BYD Premium HVS

This series of batteries consists of battery modules of 2.56 kWh that can be connected in series with each other for a total number that can range from 2 to 5 modules, from 5.1 kWh to a maximum of 12.8 kWh per system.

Each of these can also be put in parallel with two other systems, thus generating an accumulation of 38.4 kWh.

Each “tower” can reach 512V of nominal voltage with a maximum current output of 25A.

BYD Premium HVM

These systems, unlike the HVS, can be formed from 3 to 8 battery modules connected in series of 2.76 kWh, for a total of maximum 22.1 kWh. Also, in this case, I can parallel up to 3 systems reaching a total storage capacity of 66.2 kWh.

At any time it is possible to add new battery modules or storage systems to a system with already installed HVM batteries.

The system has an IP55 degree of protection and can work in a temperature range from -10 °C up to 50 °C.

The guarantee, on the other hand, for both systems, is 10 years.


BYD: Battery-Box Premium HVS / HVM – high voltage – from 5.1 to 66.2 kWh

The new high voltage batteries of the BYD brand are devices compatible with many single-phase and three-phase inverter brands.


  • composed of 2 to 5 HVS battery modules
  • capacity of 5.1 to 12.8 kWh


  • composed of 3 to 8 HVM battery modules
  • capacity of 8.3 to 22.1 kWh

These two types of high voltage batteries, HVS and HVM, are distinguished by different characteristics.

The Lithium Iron Phosphate (LFP) battery offers maximum efficiency and durability combined with high safety standards.

Both models can adapt to all types of needs, thanks to the excellent flexibility and ease of use

  • 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
  • 2300A short-circuit current

Battery-Box Premium HVS

The Premium HVS Battery-Boxes is composed of a minimum of 2 to a maximum of 5 modules connected in series, to obtain a usable capacity from 5.1 to 12.8 kWh per single battery pack. In addition, up to 3 series of modules can be paralleled at any time, thus reaching a maximum total capacity of 38.4 kWh.

Battery-Box Premium HVM

The Premium HVM Battery Boxes are made up of 3 to 8 modules in series for an overall capacity of between 8.3 and 22.1 kWh. As in the case of Premium HVS, up to 3 series of modules can be paralleled, for a maximum capacity of 66.2 kWh.

Both products have an operating temperature range of -10 to +50 ° C, with a charge/discharge efficiency of 96%. They have an IP55 degree of protection and a 10-year product guarantee.
