In a DC power system, the uninterruptible power system (UPS) takes in primary power — usually utility AC — and outputs DC voltage while providing backup power from the integrated batteries in the event of an extended power outage.
3. Batteries — Depending on the application, a DC system may use VRLA, lithium-ion, NICAD or wet cell batteries, with almost all batteries running in a series due to the amount of power needed.
The components of the dc power system addressed by this document include lead-acid and nickel-cadmium storage batteries, static battery chargers, and distribution equipment. Guidance in selecting the quantity and types of equipment, the equipment ratings, interconnections, instrumentation and protection is also provided.
Guidance in selecting the quantity and types of equipment, the equipment ratings, interconnections, instrumentation and protection is also provided. This recommendation is applicable for power generation, substation, and telecommunication applications. Scope: This recommended practice provides guidance for the design of stationary dc power systems.
Although DC units may vary depending on the type of application they are designed for, most systems consist of five main components: 1. Rectifier / Charger — An electrical device that converts alternating current, the rectifier has two main purposes.
This system, referred to as the PV-integrated battery energy storage system—dc series (PVBESS-DCS), simplifies integration and enhances power density by leveraging the inherent voltage-source characteristics of batteries and adopting the concept of partial power processing.

DC System Sizing Principles
Batteries provide DC power to the switchgear equipment during an outage. Best practice is to have individual batteries for each load/application. *Lead-Acid has a minimum sizing duration of 1min. Why??? The lower limit should allow for maximum usage during discharge. The narrower the voltage window, the larger the battery capacity has to be.
