STS Cabinet and Backup Solutions

The STS (Static Transfer Switch) cabinet contains the UPS (Uninterreptible Power Supply) units, circuit breakers and other supporting devices. The ESS (Energy Storage System) cabinet, connected to the STS, allows for a rapid transition to off-grid mode (within 20 ms) in the event of a grid failure, ensuring that critical loads remain safe and constantly powered.
Our STS systems, integrated with an ESS, enable automatic switching between the electrical grid and backup power in off-grid mode in less than 20 ms. In case of grid interruption or degradation, the STS instantaneously transfers the power supply to the ESS, which provides stable energy to critical loads. This ensures operational continuity, protection of sensitive loads and voltage and frequency stability, while optimizing self-consumption of stored energy and infrastructure resilience.
