This document describes the design of a modular, scalable, and redundant UPS system. Key features include a 2000W UPS module that fits in 1U of rack space, hot-swappable power and battery modules, N+1 redundancy, ability to parallel multiple modules for increased power capacity, and flexible output connector options. The system aims to provide reliable backup power while being compact, lightweight, and cost-effective.
