Dyness Powerbox is a lithium battery solution with LiFePO4 (lithium iron phosphate) technology, suitable for energy storage applications in hybrid photovoltaic systems. Lithium battery banks are gaining wide acceptance in the photovoltaic solar energy market due to the advantages that this technology offers.
Compared to old stationary lead-acid batteries, lithium batteries have a higher energy density (lower weight and volume), a lower depth of discharge and – most importantly – a long service life with a high number of cycles. Lithium iron phosphate technology is recommended for applications where safety is an important factor. Lithium iron phosphate is non-combustible and will not catch fire in the event of defects or short circuits in the batteries.
