Our lithium-ion solar cells use BYD, CATL, Ganfeng Lithium A grade lithium iron phosphate (LiFePo4) cells, designed to last up to 15-20 years. The duration of the battery depends on various factors. Experience shows that BSLBATT energy storage battery can assume a service life of over 20 years and more than 6000 charging cycles.
The storage capacity should be selected depending on the power consumption as well as the installed PV power. Battery storage should:
