Power supply systems provider AEG Power Solutions has introduced the latest version of its Protect SC. 600 Storage Converter, now with a new outdoor enclosure which reduces global installation costs and simplifies system usage for any type of battery storage energy application, on or off-grid.
The Protect SC.600 bi-directional power converter is based on AEG's established 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 maximising profitability), or voltage control (often used to balance the voltage instability generated by integration of renewables in the grid). And its wide DC input range means it may be used with any state of the art battery technology currently available.
This enhanced Protect SC.600 version allows a seamless transition between off-grid and on-grid mode — this function is available as an option. It 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.
And this new option is seen as a 'must' 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.
Protect SC. 600 can be easily implemented in a turnkey solution including batteries and medium voltage transformers. The new outdoor enclosure has been designed to house one Protect SC.600, an optional AC low voltage circuit breaker, a communication interface as well as an auxiliary power supply. The outdoor enclosure — which can decrease the cost by 20 per cent compared to container solutions — replaces the use of containers whose weight and size make it difficult to transport and handle. With Protect SC.600, up to four units of the new outdoor system can be loaded onto a truck, and transported where on site, the complete units can be moved with a forklift truck replacing the need for heavy load cranes.
