The NESTS grid-connected and off-grid switching device can realize the fast and automatic switching of the energy storage system in the grid-connected and off-grid operating states, which is suitable for the application scenarios with power guarantee requirements.
The STS Switching Device, with modular design, suits for NESI series energy storage converter and SINY series optical storage integrated machine. STS siwtching can realize fast switching between the grid connected and off grid state within 20ms, and can effectively protect important information loads such as servers. For realizing automatic operation of energy storage station without duty, the STS transfer switch can cooperate with EMS and PCS. Each module is only 2U in height, small in size and high in power.
