BYD believes self-consumption of renewable energy is the future and says you should consume energy you generate yourself to lower your carbon footprint and avoid increases in electricity prices. To help you optimise self-consumption and save money, the company has developed a battery storage line that includes modular LV and HV solutions suitable for residential applications and a commercial battery fit for large implementations.
One of the benefits of installing a BYD B-Box solar battery is you can start small and add capacity at any time in the future to meet your needs.
BYD B-Box Solar Batteries
BYD has expanded its range of solar batteries to cater for all energy storage applications. Its battery storage line includes high voltage and low voltage options designed to be compatible with off-grid and hybrid inverters.
All BYD batteries are stackable units and cobalt-free lithium iron phosphate (LFP) batteries to maximise safety, life cycle and power. LFP is widely considered the safest lithium chemistry and the better choice for stationary applications and is why so many leading battery manufacturers choose this chemistry for their products.
