The role of inverters in energy storage systems
1, energy conversion: the inverter converts the DC electrical energy in the energy storage system into AC electrical energy to meet the demand of the grid or load. It converts the electrical energy in the energy storage system into usable forms of electrical energy to realize the effective use of energy.
2、Control and communication: the inverter can communicate and coordinate with other components of the energy storage system to achieve centralized control and management of the system. It can realize remote monitoring, fault diagnosis and performance optimization of the energy storage system by connecting with the energy management system or monitoring system.
3, isolation and protection: the inverter plays the role of isolation and protection between the energy storage system and the power grid. It separates the energy storage system from the external power grid, preventing the reverse flow of electricity or interference. At the same time, the inverter can also realize the protection of the energy storage system and power grid by monitoring the voltage, current and other parameters.
4, power control: the inverter can control the size and stability of the output power according to the load demand or grid requirements. Through the control of the inverter, the power regulation and optimization of the energy storage system can be realized to meet different power requirements.
