Complete Solar Lithium Battery System ESS Off Grid 20KW 40KWH
Features:
High Energy Density
Lithium batteries can store a significant amount of energy in a compact size, which is particularly advantageous for residential installations with limited space. This high energy density enables efficient utilization of available storage areas while maximizing the energy capacity of the system.
Depth of Discharge
Lithium batteries offer a high depth of discharge, often up to 90%, enabling users to utilize a substantial portion of the stored energy without causing detrimental effects to the battery. This feature enhances the overall efficiency of the energy storage system.
Efficiency and Low Maintenance
Lithium-ion batteries are highly efficient, with minimal energy loss during charging and discharging cycles. Additionally, they require little maintenance, reducing the overall operational costs associated with regular upkeep. These low-maintenance requirements make them an economical and hassle-free solution for long-term solar energy storage.
Safety Features
Modern lithium-ion solar batteries are equipped with advanced safety features, including overcharge protection, thermal management systems, and built-in safeguards against short circuits, overcurrent, and overvoltage1. These safety measures ensure secure and reliable operation, minimizing potential hazards and enhancing overall system safety.
