As the solar industry continues to grow and more consumers move from conventional Lead Acid batteries to lithium battery banks safety concerns arise. As videos of lithium batteries catching fire spread across social media consumers cannot help but wonder, are these backup lithium systems safe? As complex as these systems are the anwser is not as strait forward as yes or no. If installed correctly these systems pose little to no threat whatsoever. However if installed incorrectly the outcome could be catastrophic. As battery manufacturers compete to produce the most efficient lithium battery compareitively some pose much less threat of thermal runaway than others. So far the chemical composition of LFP "lithium Iron Phosphate" prove to be much less prone to thermal runaway than the compareitive NMC "lithium nickel manganese cobalt oxide". However there are some cons to LFP batteries. LFP batteries are not as resistant to cold weather and can't store as much energy as NMC Li-ion batteries. One of the most beneficial traits of the LFP battery is that it is much easier to produce due to the more domestically available materials. One of the most attractive traits to us at A-Z Solar Services is that it is not composed of cobalt like NMC batteries. Cobalt is a very toxic chemical that is hard to recycle and could poison the ecosystem which works against our main goal to help maintain homeostasis.
