Discover BYD's high-voltage batteries: HVS & HVM

What makes BYD batteries special? Their compatibility. The HVS and HVM batteries can be used with various inverter brands, which is not the case with all manufacturers. This also makes these batteries excellent as a retrofit option for customers with an existing PV system.

BYD has chosen to develop a High Voltage Small (HVS), a High Voltage Medium (HVM) and a High Voltage Large (HVL) battery, covering the full spectrum of system sizes. The batteries are suitable for residential and commercial use and are modularly expandable. It is important to know that the HVS and HVM modules are not interchangeable.

The similarities and differences

The HVS and HVM battery modules look identical, but differ in the maximum number of stackable batteries per tower. The right model depends on your customer's needs. Both models come with the same Battery Control Unit (BCU) , consisting of a grey base and a grey top cover. The HVM series has a maximum height of 2160 mm, while the HVS line is max 1461 mm high.

Both the HVM and HVS have internal wiring, making them easy to use and install. These batteries can operate both on- and off-grid, depending on the battery or hybrid inverter used. Furthermore, the HVS/HVM batteries meet the highest safety standards (VDE 251050), an IP55 rating and are developed with cobalt-free lithium iron phosphate (LFP), currently the safest technology for home batteries. This LFP technology does make them heavier on average than other storage batteries. They can operate in temperatures as low as -10° C. Not all batteries can do that, so this is a significant advantage.

BYD B-BOX premium HVS

The BYD battery from the HVS series, which stands for High-Voltage Small, has the smallest capacity, as the name suggests. A standard package consists of 2 battery modules with a combined capacity of 5.1 kWh. The HVS is expandable to a maximum of 5 modules. This gives you a total capacity of 12.8 kWh. Each individual module has a capacity of 2.56 kWh with an internal voltage of 102.4V. Whether you can use a total of 5 modules depends on the battery or hybrid inverter that is used. You can connect a maximum of 3 battery towers in parallel - so 3 x 5 battery modules - which gives you a maximum capacity of 38.4 kWh.

BYD B-BOX premium HVM

The BYD HVM battery, or High-Voltage Medium, is larger in terms of power than the HVS. A basic package consists of 3 battery modules with a combined capacity of 8.3 kWh. This model can be expanded to a maximum of 8 modules with a combined capacity of 22.1 kWh. Each module has a capacity of 2.76 kWh and an internal voltage of 51.2V.

There is also a minimum for this model. You must use at least 3 modules for a functioning battery. A maximum of 3 identical systems can be connected in parallel - so 3 x 8 - which achieves a maximum capacity of 66.2 kWh.
