About the BYD B-Box Premium
Safe Battery Chemistry
The BYD Lithium Iron Phosphate (LFP) chemistry is recognised as one of the safest Lithium chemistries currently in use.
Safe Battery Construction
Built with the same battery modules as BYD's Electric Vehicles gives these 'stationary' battery systems the durability of devices designed for motive and high vibration applications.
High Power Output
BYD's High Peak Discharge capability makes them ideal for off-grid applications where surging loads are used.
Usable Energy Ratio
With smart design the B-Box can deliver a usable energy ratio of 96%!
Easy Installation
The B-Box systems have been carefully designed to simplify installation. The modular nature of the system components means they can be installed by a single technician.
Flexible Extension
The modular design also allows for flexible expansion of system sizes over the whole lifetime of the system!
Natural Cooling
Using natural convection cooling allows the B-Box to achieve the highest system efficiency as well as enabling operation without the noise of fans or pumps.
