Scalable storage solution with KOSTAL PLENTICORE and BYD Battery-Box HVM+
The BYD Battery-Box HVM+: The powerful energy storage system for private and commercial applications compatible with KOSTAL inverters from the PLENTICORE series
The BYD Battery-Box HVM+ is an innovative high-voltage battery system for private and commercial photovoltaic systems. Thanks to its modular design, the storage capacity can be flexibly adapted to individual requirements - from 8.3 to 22.1 kWh per tower.

More options, more efficiency: the new generation of the BYD Battery-Box HVM+
Equipped with safe lithium iron phosphate technology, the Battery-Box HVM+ impresses with its long service life, maximum safety and impressive performance. The storage system delivers up to 50 A continuous current and 80 A peak current, making it ideal for applications with high energy requirements.
The integrated balancing technology ensures optimum cell utilisation, while the patented plug-in system enables quick and easy installation - without any cabling between the modules. Even after the initial installation, the system can be expanded at any time - regardless of the state of charge.
Compatibility with the single-phase and three-phase KOSTAL inverters from the PLENTICORE series makes the HVM+ the ideal solution for larger homes or small commercial installations.
