Protect SC UL Bi-Directional Energy Storage Power Converter

1/1

Protect SC is a bi-directional power converter from AEG Power Solutions with IGBT technology. The converter is the core element of any battery energy storage system as it charges and discharges batteries to store or provide power according to the application requirement (frequency control, peak shaving, energy shifting), or voltage control. Protect SC provides an outstanding conversion efficiency factor for both the charging and discharging phases. Thanks to its wide DC input range, it may be used with any state of the art battery technology currently available. The latest option available features a seamless transition between on-grid and off-grid mode. This extends the battery energy storage system’s usage beyond its core functions to back-up in the event of a black-out. The system can also be provided as a turnkey solution including battery and medium voltage transformer.
