Energy storage system cost analysis: batteries and energy storage inverters are the main parts

The cost of the energy storage system is mainly composed of batteries and energy storage inverters, which account for 80% of the total cost, of which the energy storage inverter accounts for 20%. The key component in the energy storage inverter is IGBT, whose performance directly affects the performance of the energy storage inverter and accounts for 20%-30% of the inverter value. IGBT plays the role of voltage conversion, frequency conversion and alternating conversion in the energy storage system, and is an indispensable component.
