Running two or more UPS units in parallel, by configuring a parallel UPS system, provides a greater power capacity or ensures a resilient system by adding redundancy.
SolarEdge offers a parallel option kit, which contains a communication cable (one per unit), enabling a quick and easy parallel deployment for your critical loads.
A parallel UPS configuration is achieved by connecting the communication cables in a ring arrangement. Parallel communication keeps the all the connected UPS synchronized with each other and controlling is achieved by utilizing a Master/Slave setting. One UPS acts as a master, as its controller determines the operation behaviour, while the other UPS follows accordingly.
A parallel UPS configuration can be connected to a common battery backup (common DC) or to a decentralized DC (each individual UPS unit is connected to its respective battery cabinet).
A designated parallel configuration kit supports its respective product.
- Greater power capacity
- Resilient UPS system
- Load is shared between all the units
- If a UPS is manually shut down (system off), the other units will continue working
