備用電源
能量存儲系統可在電源能量短缺的情況下提供備用電源。在掉電期間，由儲能系統維持用戶設備運行。
直流母線電壓一直保持不變，以確保不會發生過電壓和欠電壓。同時通過與市電的固定連接不斷地給電池充電，因此即使短暫的電壓突降，電池可正常使用。
峰值
在工業電網中，可將存儲的能量用作冗余電源。這也意味著用戶可以在額定負載下運行電機，并使用電池供電來滿足峰值需求。這樣做的好處是，設備在滿負載下運行發電機比在部分負載下運行更有效率。因此，您可以減小發電機的尺寸，并獲得高的投入產出比。
降低成本和設計時間
丹佛斯的工業直流備用電源系統提供備用冗余電源，能夠確保應用程序的大正常運行時間，避免因供電不足造成原材料浪費現象的產生。
同時，電池存儲可以為峰值負載供電，從而可以減少發電機的尺寸，降低企業支出成本。更重要的一點是，系統可以通過直接向臨界逆變器設備部分供電而不是為整個系統供電，達到節約能源的效果。
