Sola/Hevi-Duty offers a wide variety of uninterruptible power supplies which consist of four topologies and classes of power protection. the unit that you wish to duplicate – whether it's a generator, UPS, or cooling unit. It enables huge savings to be made in UPS units and therefore contributes to an improvement in the efficiency of the overall system. ‘N+1’ and similar redundant configurations similarly bring resilience to failure at a system level. N+1 redundancy (or parallel redundancy) is a safeguard to ensure a UPS system's availability in the event of component failure — especially in …3N/2 redundant The three-to-make-two or 3N/2 redundant configuration provides nearly 2N reliability with N+1 capital and operating costs, but with added load management challenges. In the world of datacenters, an N+1system, also called parallel redundancy, and is a safeguard to ensure that an uninterruptible power supply (UPS) system is always available
