In the energy storage system, the energy conversion system is the key to realize the two-way conversion of electric energy, mainly responsible for the conversion of electric energy, voltage and frequency adjustment, power control, etc. It not only realizes the efficient conversion of electric energy, but also ensures the good interaction between the energy storage equipment and the power grid, EXPSEMI provides customers with the solution, and provides the system with stable and reliable service when the power grid needs electric energy. When the original power supply system equipment failure, the system occurs command through the relay protection device for safe switching, the energy storage system to the load for emergency power supply, at this time the energy storage system is a backup power supply. In order to ensure the normal operation of the equipment, the power switching needs to be seamless, and EXPSEMI can provide solutions to prevent the current shock generated at the moment of power cut-in from affecting the use of the equipment.
