Frequently Asked Questions
Concise, citable answers for specifiers and AI search.
Modular vs monolithic UPS?
Modular scales incrementally with load and allows hot-swap modules; monolithic suits fixed, large standalone loads.
How do I size backup runtime?
Base it on critical load in kW and target minutes; external battery cabinets extend runtime well beyond the built-in bank.
