A global technology developer of uninterruptible power supplies (UPS) requested an energy storage system to backup their power supply for mission critical applications. They wanted a system that was more reliable than lead acid and with less maintenance. They also preferred to have a more efficient static solution over that of a more wasteful rotary UPS.

Valence provided a solution that allows the UPS equipment to be dependably used for over a decade with limited maintenance. In this case, each 480 VDC UPS battery cabinet is able to support a 275 kVA load for 1 minute of backup utilizing only 20 standard U-Charge P40-24 modules. Three cabinets in parallel meet the 1 minute rating of a 750 or 825 KVA load. Since they are half the weight of VRLA battery cabinets, the Valence solution allows for an easy floor installation.
