What is LiFePO4 solar battery?
Lithium iron phosphate (LiFePO4) batteries are best known for their strong safety profile, the result of extremely stable chemistry. When subjected to hazardous events, such as collision or short-circuiting, they won’t explode or catch fire, significantly reducing any chance of harm.
Why choose lithium LiFePO4 battery for the solar application?
The lithium iron phosphate (LiFePO4) battery, also called LFP battery (with “LFP” standing for “lithium ferrophosphate”), once compared to If we compare lithium iron phosphate (LiFePO4) battery to lead acid batteries, offer significant advantages, including improved discharge efficiency, longer life span and the ability to deep cycle while maintaining performance. Indeed they are often more expensive than lead acid batteries but the minimal maintenance and infrequent replacement makes lithium LiFePO4 battery a valuable investment and smart long-term solution. Lithium iron phosphate (LiFePO4) batteries are not new, however latest developments and improvements are making this type of battery natural choice for many applications, including solar industry. Below we will mention several reasons why we believe that lithium iron phosphate (LiFePO4) battery is the best solution for the solar application.
Lithium iron phosphate (LiFePO4) batteries are best known for their strong safety profile, the result of extremely stable chemistry. When subjected to hazardous events, such as collision or short-circuiting, they won’t explode or catch fire, significantly reducing any chance of harm. Useable capacity In contrary to lead-acid batteries 100% of the nominal capacity of LiFePO4 batteries can be used. When you take a 100Ah battery you can use between 30Ah to 50Ah with a Lead-Acid battery, opposed to 100Ah with a LiFePO4 battery.
LiFePO4 batteries have much longer life span than lead acid batteries and they can work perfectly for the period of 5-7 years and cycle life can be up to 2500 cycles. A slower rate of capacity loss compared to other formulations might offset the trade off to some degree. After a year, a LiFePO4 cell typically has approximately the same energy density as a LiCoO2 lithium ion cell. Battery charging time is also considerably reduced, another convenient performance perk.
Both lead-acid batteries and LiFePO4 batteries lose capacity in cold environments. The loss of energy with LiFePO4 batteries is minimal. It will still have 80% of capacity at a temperature of -20˚C, compared to 30 percent when using an AGM battery. For many locations with extreme cold or hot weather the LiFePO4 battery is the best choice.
Comparing to lead acid batteries, LiFePO4 batteries are almost four times lighter. For example, one 150ah lead acid battery is around 50kg /110lbs in weight, on the other side LiFePO4 battery is only 15kg/30lbs. For many solar applications this presents huge benefit that can lower installation cost and speed up the project execution.
LiFePO4 batteries can be charged fast to the full 100 %. A lead-acid battery must be charged with an absorption phase to charge the final 20 percent.
Can we use lithium-ion battery for inverter?
You can charge it with the help of the grid power or by using solar energy. Its integrated Li-Ion battery offers a faster charging speed, longer life and up to 15% more efficiency than lead acid battery. This Luminous inverter is safe for home use as it is devoid of any open wires.
LiFePo4 Battery: What makes it ideal for your Inverters!
Batteries that have lithium as their anode are known as Lithium batteries. Lithium batteries can be divided into three on the basis of the technology used in it. They are Lithium-Ion, Lithium Phosphate and Lithium Polymer batteries. Lithium Iron batteries, otherwise known as LiFePo4 batteries are the most advanced one among lithium batteries. Like any other batteries, Li-iron (LiFePo4) batteries consist of components like cathode, anode, electrolyte, separator and current collector. In a Lithium Iron battery, Lithium Iron Phosphate is the cathode material and a graphite carbon electrode with metallic backing is the anode.
Why LiFePo4 batteries for Inverters?
Its a known fact to all that batteries plays a vital role in determining the performance and life span of home inverters. In comparison with other battery technologies such as Nickel, Silver and Lead Lithium batteries have wide acceptance all over the world. Lithium has a high electrochemical potential and can be recharged repeatedly. Therefore lithium batteries have minimal maintenance cost and a longer life cycle.
Along with the advantages that are common for lithium batteries, Lithium iron (LiFePo4) or Lithium Ferrous Phosphate Batteries have greater thermal and chemical stability hence they got better safety aspects as well. They really can improve your inverter’s overall efficiency as LiFePo4 batteries are more reliable, stable and have zero maintenance as well.
LiFePo4 batteries have high charge and discharge efficiency and a higher capacity than ordinary batteries. They have constant output power.
• They are more lightweight than other batteries. Therefore they can bring considerable changes to the design and overall weight of your power backup system.
• They are environment friendly and non-toxic.
• LiFePo4 have a 10 times longer lifespan than the normal lead-acid batteries with almost zero maintenance. Therefore it can increase the cost-efficiency of your home inverter.
• hey have twice the battery capacity and can handle the temperature variations more effectively.
• LiFePo4 batteries have no memory and they don’t need any scheduled recycling.
• They have a higher energy density along with better safety aspects.
• Lithium Iron batteries need less time to charge.
• They are generally incombustible while mishandling. They have got better stability during short circuits and overcharging. So they are one among the safest batteries available now in the market.
• They have a constant discharge voltage, that stays close to 3.2 V till the battery gets exhausted.
• Like other lithium batteries, Priming not needed for LiFePo4 also.
