Why You Need A High Voltage Lithium Battery System?

  • Higher Conversion Efficiency
  • Increased Independence from the Grid
  • Provides Greater Flexibility
  • Lower Cost, Larger System
  • Faster Charging and Discharging
  • Better Suited for Peaking Applications
  • Can Save Energy

Taking the field of solar lithium storage systems as an instance, picture that when an 10kW hybrid solar inverter is utilized with a lithium battery as a low-voltage storage system, the DC voltage of the battery for house solar applications is commonly 48V or 51.2 V. Even if we utilize a relatively large nominal present, claim 200A, the optimal power that the battery can provide is 10kW (51.2 V x 200A = 10.24 kW), a value that does not meet the optimal result power of the inverter.

On top of that, there are lots of commercial power storage applications with power system results of 30kW, 60kW, 100kW or even 500kW power ability. In these application scenarios, we need to utilize high-voltage lithium battery systems to lower the discharge existing.
