Battery Backup Power UPS For Load Shifting And Backup Power
Battery Backup Power, Inc. provides UPS (uninterruptible power supply) systems for commercial and industrial backup power applications. As load shifting is becoming more desirable for electrical utility rate reduction, these UPS systems can serve both purposes flawlessly with the addition of a 3 pole contactor and digital timer (see above diagram).
If a power outage occurs or the timer triggers the contactor to open during peak hours (typically 4 p.m. to 9 p.m.), the Battery Backup Power, Inc. UPS will power the facility. The contactor and timer allow the UPS to continue to act as a backup power system (primary purpose) and load shifting power source for rate reduction (secondary purpose). The power consumption from the utility will drop to 0 during the time the UPS is operating when the contactor on the input side is open. The timer should be set to close the contactor after peak hours pass allowing the UPS to recharge during lower rate hours. This setup is significantly more cost effective and less time consuming to implement than an ESS system with bi-directional inverter as the UPS will not back feed the utility in the event of a power failure so no utility approval is required. Battery Backup Power, Inc. UPS systems are all double conversion (online) which means that they constantly regulate voltage and eliminate and disruption of power during a power failure or transition to backup only (0 ms transfer delay). Even the most sensitive electronics will not be impacted by the switching.
Two considerations must be made before implementing a UPS as a dual purpose backup and load shifting system.
1. The UPS size/capacity (KVA/KW rating) must be greater than the facility's peak load.
2. The UPS system battery capacity (Amp Hours or KWH) should be 2 to 4 times the size needed to provide power during the peak rate hours. For example, if the load is an average of 4,000 watts from 4 p.m. to 9 p.m., that is 20,000 WH (watt hours) or 20 KWH (kilowatt hours). The battery capacity should be at least 40 KWH. Alternatively, this system can be scaled down and used on a sub panel rather than the main panel.
Below is a list of single phase and 3 phase UPS systems that have expandable battery capacity options using external battery packs or cabinets.
