[0002] Energy storage inverter, also known as energy storage converter, is an important energy conversion device. Its function is to convert electrical energy from one form to another and ensure efficient use of energy. The key function of this inverter is to convert DC to AC or AC to DC to meet the needs of different power systems. Energy storage inverters are widely used in energy storage systems. In the field of renewable energy, such as solar and wind power generation systems, energy storage inverters play a vital role.

[0003] The current energy storage inverter usually consists of a host and a junction box.
