Energy storage system switches from on-grid to off-grid

March 12, 2017 // By Nick Flaherty
AEG Power Solutions has launched an energy storage system with an outdoor enclosure to reduce global installation costs and simplify designs with any type of battery.

The Protect SC.600 bi-directional power converter is based on the 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).

The Protect SC. 600 provides conversion efficiency for both the charging and discharging phases. With a wide DC input range, it can be used with any state of the art battery technology currently available.

This version allows a seamless transition between off-grid and on-grid mode 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 and provides 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 aimed at battery energy storage  remote areas or islands where grid reliability is uncertain or for full off-grid applications in similar geographies.
