We have a generator – do we still need a UPS?
An auxiliary generator provides back-up power just as a UPS does but requires much more time to kick in and stabilize before it can start supporting your critical loads. Hence, a UPS is required to ensure that the equipment stays running until the generator kicks in. In addition, the UPS also improves the quality of the power produced by the generators.
