Uninterruptible Power Supply (UPS), a device that is able to ensure and maintain uninterruptible power supply for a limited period of time, mainly by batteries that come into operation immediately (0.0 seconds) when there is a power outage from the mains.
The standalone configuration (Figure 1), is the most common configuration utilized in UPS applications because it contains fewest number of major components. This system utilizes AC power (typically utility power) and converts it to DC through the rectifier. The regulated DC power is supplied to both bank of batteries and to the inverter.
Over the years UPS designers have come up with ways to harness maximum power capacity within a finite space. This is often achieved by scaling the number of UPS systems in a configuration to cope with the; load requirement, budget, existing infrastructure and risk tolerance.
A capacity or ‘N’ system is the most common type of UPS installation and the minimum requirement to provide power protection to the critical load. Also referred to as ‘power parallel’, It comprises a single standalone UPS module or a paralleled set of modules with a matched capacity to the critical load projection.
It is therefore sufficient to keep the UPS connected to the power supply, even if not in use, so that the batteries remain alive and active . The UPS must always be connected to the batteries and report any disconnections or malfunctions promptly so that it is able to function correctly .
As it is not advised to consistently run a UPS at over 50% load capacity, a parallel redundant, or ‘N+1’, configuration consists of one UPS (‘N’) sharing the critical load evenly with another UPS system (‘+1’).
The global industrial and commercial energy storage market is experiencing explosive growth, with demand increasing by over 250% in the past two years. Containerized energy storage solutions now account for approximately 45% of all new commercial and industrial storage deployments worldwide. North America leads with 42% market share, driven by corporate sustainability initiatives and tax incentives that reduce total project costs by 18-28%.
