Features of the Dyness Powerbox battery bank

Banks of lithium batteries are gaining wide acceptance in the photovoltaic solar energy for the advantages that this technology offers.

Compared to old stationary lead acid batteries, lithium batteries have higher energy density (lower weight and volume), lower discharge depth and – most importantly – long service life, with a high number of cycles.

Among the various versions of existing lithium cells, the Dyness chose to work with technology LiFePO4 (iron phosphate), the main advantage of which is high fire safety. While traditional lithium-ion cells can catch fire when overheated, LiFePO4 cells do not present this risk.

Lithium iron phosphate technology is recommended for applications where safety is an important factor. Lithium iron phosphate has excellent thermal and chemical stability. This battery remains cool even in aggressive environments, subject to high temperatures.

O lithium iron phosphate It is also non-combustible during rapid charging and discharging or when there are short circuit problems. Lithium iron phosphate does not normally suffer from thermal runaway as the phosphate cathode does not burn or explode during overcharging or overheating as the battery remains cool.

Another safety advantage of lithium iron phosphate involves disposing of the battery after use. Traditional lithium-ion batteries require special disposal care. On the other hand, lithium iron phosphate is non-toxic and can be disposed of more easily.

Lithium iron phosphate technology is suitable for applications where safety and longevity are desired but do not need extremely high energy density.

In addition to use in electric vehicle traction systems, where high temperatures are typically encountered, lithium iron phosphate is also ideal for stationary applications as the LiFePO4 battery is slightly heavier and bulkier compared to other available technologies. .
