BYD Battery Storage Systems

Battery Storage Options For Home Or Business.

Battery stroage is now more relevant than ever, with ever increasing energy prices and consumers looking for ways to maximise their PV systems. The good news is systems are better and now priced at a range that consumers can now make a financial case to add Battery Storage to an exisiting sytem or include with a new system.


BYD Lithium Iron Batteries

BYD B-Boxes features a modular design allowing flexible battery storage sizing, extension throughout its lifetime, easy installation and uninterruptible maintenance.

Different versions for both 48V (LV) and high voltage (HV) storage systems.

Features a modular design allowing flexible battery storage sizing, extension throughout its lifetime, easy installation and uninterruptible maintenance.

Safe Battery Chemistry
B-Box uses a LiFePO4 chemistry battery which has been widely recognized as one of the safest battery technologies. This features a stable structure with a thermal runaway temperature of over 480℃. It is designed for residential and commercial applications with absolute safety.

High Power Output
B-Box is able to reach a peak 2C rate to support critical loads such as A/C and pumps, etc.

  • Suitable for Emergency-Backup and Off-Grid applications

Natural Cooling
B-Box is designed with natural cooling providing optimumefficiency.

Temperature derating: Like many lithium batteries temperature effects how fast the battery can change and discharge. These latest BYD batteries have a very wide operating temperature range and will work at their peak performance ratings most of the time in most installations. Discharging isn't effected much by temperature, charging is effected mostly: below 5°C charge rate will reduce to 0.3C, below -2°C 0.05C.
