Our Advantages
Applications
Charging station
Relays are applied in critical functions of charging stations, including main circuit switching control, safety power disconnection, and feedback detection. Taorelay high-voltage relays feature high breaking capacity and superior insulation performance, making them indispensable core components for new energy charging systems.
Photovoltaic Energy Storage
Our relays are widely used in the photovoltaic energy storage sector, primarily for inverters, energy storage kits, battery management systems, DC distribution boxes, and similar applications.
Smart Home Appliances
Relays are widely used in smart home appliances, serving as a bridge between control circuits and load circuits. They play a crucial role in automatic control, safety isolation, and remote operation.
Smart Grid
As power grids progressively evolve toward digitalization, automation, and distributed systems, the functions of relay protection continue to expand. This evolution extends beyond traditional power protection into intelligent control domains such as communication, automatic reclosing, and load management.
