What is a Solar Lithium Battery?
A Solar Lithium Battery is a rechargeable energy storage device used in solar power systems to store electricity generated by solar panels. These batteries typically use Lithium Iron Phosphate (LiFePO₄) or Lithium-ion (Li-ion) chemistry due to their high energy efficiency, safety, and long life.
Working Principle
Daytime Operation: Solar panels generate DC electricity → Charges the lithium battery through a charge controller. Energy Storage: Excess energy not immediately used is stored in the battery. Nighttime / Power Outage: Stored energy is discharged to supply electricity via an inverter (DC to AC conversion). Battery Management System (BMS): Monitors temperature, voltage, current, and controls charging/discharging for safety and performance.
