More independence for your home
More energy and possibilities with KOSTAL PLENTICORE and BYD Battery-Box HVS+
BYD Battery-Box HVS+: The smart high-voltage battery for private applications compatible with KOSTAL inverters from the PLENTICORE series
The BYD Battery-Box HVS+ is a powerful, scalable high-voltage battery system for private and commercial applications. Thanks to its modular design, the storage capacity can be flexibly adapted - from 5.1 kWh to 38.4 kWh per system.

More capacity, more efficiency: the new generation of the BYD Battery-Box HVS+
The HVS+ impresses with maximum safety with lithium iron phosphate cells (LFP), intelligent functions such as automatic SOC adjustment and remote maintenance via OTA as well as a maximum charging/discharging capacity of 12.8 kW per tower.
Installation is particularly easy thanks to the plug-in module system - without any internal cabling. Compatibility with the single-phase and three-phase KOSTAL inverters from the PLENTICORE series makes the HVS+ the ideal solution for single-family homes with medium energy requirements.
