Lithium energy storage batteries are mainly used in Large Scale ESS / Low Voltage Residential ESS / High Voltage Residential ESS and other similar application, with low leak current, long calendar life and cycle life. The system can be widely deployed in the grid level energy storage, higher capacity PV
energy storage and data center power backup.
In recent years, more and more people choose to use Lithium Iron Phosphate Batteries for their solar system. They can serve as a backup source, as an energy storage centre or as a battery of daily usage in stand-alone systems (daily charge and discharge) just like they will do using lead acid-batteries. That’s because Lithium Batteries have far better performance than the Acid ones and they can handle better the task of storing and delivering the energy we need every day.
Here we share with you the advantages that Lithium Iron Phosphate Batteries have and why they are ideal for energy storage:
Battery Life: Lithium iron phosphate batteries used in solar systems have a lifecycle six times longer than the AGM conterparts. This is because the lithium iron phosphate option is more stable at high temperatures, so they are resilient to over charging. Additionally, lithium iron phosphate batteries can be stored for longer periods of time without degrading. The longer life cycle helps in solar power setups in particular, where installation is costly and replacing batteries disrupts the entire electrical system of the building. Solar panels and energy management systems currently have a life cycle of up to 20 or 30 years. A battery that remains efficient after more cycles will better match the lifespan of the solar power system as a whole.
Depth of Charge: The DoD of a battery is the amount of the stored energy in the battery that has been used, as compared to the total capacity of the battery. Most batteries come with a recommended DoD in order to maintain the health of the battery.
Lithium ion solar batteries are deep cycle batteries, so they have DoDs around 95%. Many lead acid batteries only have a DoD of 50%. This means you can use more of the energy that’s stored in a lithium ion battery without having to charge it as often.
Lower Environmental impact: Lithium iron phosphate batteries are built with non-toxic materials: iron, graphite and copper. They are easily recyclable, even able to be repurposed as new batteries. The longer lifespan of lithium iron phosphate batteries naturally makes them better for the earth. Manufacturing new batteries takes energy and resources, so the longer they last, the lower the overall carbon footprint becomes. Additionally, the metal oxides in the normal lithium-ion batteries have the dangerous potential to leach out into the environment. While batteries are intended to be disposed of safely, many wind up in landfills, causing severe health issues for anyone living nearby. Lithium iron phosphate batteries contain phosphate salts instead of metal oxides, which have a substantially lower risk of environmental contamination.
Safety: In solar applications, where batteries are often housed in residences or in close proximity to highly occupied office buildings, safety is an extremely important factor to consider. Lithium iron phosphate solar batteries are slight larger than the normal Lithium ones (but still much smaller and lighter than the AGM counterparts) because its energy density is designed to reach the maximum safety. Moreover, the built-in Battery Management System is monitoring constantly the voltage, current, charging and discharging state of itself. When it detects abnormalities, it can take correspondent actions to avoid any danger. The lithium iron phosphate solar batteries can even communicate with the inverters/chargers and tell them how to charge themselves correctly to be safe and extend their lifespan!
For reliable, efficient solar energy storage, it’s hard to beat lithium ion batteries solar. Despite the higher initial cost, greater longevity and enhanced performance make lithium-based batteries a more cost-effective option for many applications. Instead of replacing your batteries every few years, you may only need to replace lithium ion solar batteries once over the entire lifespan of your solar energy system.
