For businesses that run in a critical reliability environment, power disruption can be catastrophic. With a single UPS backup, You are often at the risk of losing your operations in case of a single minor failure. For that reason, most businesses in the present times, prefer to deploy a modular UPS to power their functioning.
A Modular UPS System – Eaton Industries is a combination of multiple smaller UPS modules as a single unit. These modules provide redundant power protection that is proportionate to a single large UPS. You can also opt for additional modules to cover the failures and get uninterrupted redundancy. Modular UPSs have become a staple for power-critical units and are increasingly preferred in many industries for the following reasons.

Low Installation Cost
Modular UPSs are drastically different from parallel and scalable UPSs. They often prove to be more cost-effective than their counterparts in several aspects. Installation is one of those aspects where a modular UPS can slash down your expenses significantly. Consider a scenario where a unit has a power protect requirement of 100KVA with N+1 redundancy. When you choose a single UPS you have to go for 2 free-standing 100KVA systems. However, you can easily satisfy these requirements with 6 20KVA modules making it a 120KVA modular solution.
Ease of Delivery and Positioning
A single parallel or standalone unit is bulky and can be difficult to deliver and rightly install at a given site. Their size and weight impede their mobility and cause issues in installation. On the contrary, a modular UPS comes in parts. The parts are delivered and then assembled at the site. This ability increases accessibility and reduces the cost as well.
Scalable Load and Greater Efficiency
UPS working with 100% load do not deliver their best performance efficiency. Modular UPS allows you to maintain a high value for the ratio of load and UPS capabilities. The elevated value of this metric helps to achieve optimum efficiency even when you are scaling up.
Low MTTR (Mean Time to Recover)
In case of overload and failure, a standalone UPS will go onto a bypass and will have to be isolated to repair. While working with modular UPSs, you only need to remove and replace the faulty unit. Replacement can be done very quickly and only takes a few seconds. The process can be performed in live conditions without cause loss of power.
Same Infrastructure More Power
Modular UPS dramatically increases the backup capability of your existing infrastructure. Imagine your unit already has 2 x 100KVA standalone UPSs deployed. The maximum power you can draw is 100KVA to ensure that the UPSs are not overloaded and provide the necessary redundancy. However, you can install one 20KVA additional modular unit and utilize the whole 200KVA power of the system.
Affordable Batteries
Installing more than one parallel or standalone UPSs would require separate batteries for each one of them. On the other hand, modular UPSs, as a general rule, have a centralized battery that is shared by all the modules. This significantly reduces the amount you need to spend on batteries and also reduces the overall cost of ownership over the lifetime of these systems.
