Lithium battery BYD B-Box HV 7.7 kWh | High voltage storage

Efficiency and safety in high voltage: BYD B-Box HV 7.7

The BYD B-Box HV 7.7 kWh represents the cutting-edge engineering in the sector of lithium batteries. When working in a range of high voltage (240V - 338V), this system drastically reduces the passage currents and heat losses, achieving that the use of the energy generated by your photovoltaic plates be much more efficient than in conventional low voltage systems.

Modular and scalable design

On Tienda Solar we value the growth capacity of your projects. The B-Box HV series allows a flexible configuration; The 7.7 kWh model can be extended by adding additional modules of 1.28 kWh to reach a maximum of 9 units per tower (11.52 kWh). This scalability ensures that your storage system can be adapted to future increases in the electrical consumption of your home or trade.

Security LifePo4 without maintenance

Thanks to the chemistry of Iron and lithium phosphate, This battery is intrinsically safe and stable, eliminating the risks of thermal leakage. In addition, it is a team designed to "install and forget", since it does not require any type of maintenance newspaper. Its elegant and compact design (580 x 1014 x 380 mm) allows it to integrate it aesthetically into any interior space.
