The Protect SC.600 bi-directional power converter from AEG Power Solutions with IGBT technology is based on their Protect PV solar inverter platform. The core element of any battery energy storage system, the converter charges and discharges batteries to store or provide power according to the application requirement such as frequency control, peak shaving, energy shifting (temporary storage to re-inject power when maximizing profitability), or voltage control (often used to balance the voltage instability generated by integration of renewables in the grid). Thanks to its wide DC input range, it may be used with any state of the art battery technology currently available.
The enhanced Protect SC.600 version allows a seamless transition between off-grid and on-grid mode. This function is available as an option. This extends the battery energy system’s usage beyond its core functions, such as peak shaving for system back-up in the event of a grid blackout. This presents an additional benefit for any industrial or commercial customer who invests in battery systems primarily to decrease their energy costs and have an all-in-one installation that also integrates the security of their power supply.
This new option is a must according to AEG when battery energy storage is used in remote areas or islands where grid reliability is uncertain or for full off-grid applications in similar geographies. The outdoor enclosure decreases the cost by 20 percent compared to container solutions, said AEG. Combined with outdoor transformers this is a smart solution for building battery storage installations. The new Protect SC. 600 is currently running at several sites around the world in various types of energy storage installations.
