The paradigm of requiring 15 minutes of battery backup for UPS system reliability is an antiquated and flawed perception. When properly integrated, standby generators can and will reliably take load in 10 seconds or less. This eliminates the need for lead acid batteries and extended backup time. The intolerance to the "graceful shutdown" also render 15 minutes of backup moot. The UPS system can be designed with much higher reliability and predictability using more reliable backup energy methods and applying proper design techniques. This paper discusses the issue and methods of implementing a short ride through system with higher reliability and predictability than with traditional methods.
