APR 143G Fundamentals of Battery-Based PV Systems

Lecture Hours: 4
Credits: 4

Builds a foundation for understanding many battery-based applications, in which the complexity far exceeds that of a grid-direct PV system. Addresses load analysis along with other critical design criteria such as battery bank design, equipment options, and electrical integration of system components. Covers component options in detail, including batteries, charge controllers, and battery-based inverters. Investigages different battery chemistries, associated pros and cons, and cost comparisons along with safety and maintenance considerations unique to battery-based PV systems.

Student Learning Outcomes:

Define electrical characteristics of battery systems and identify common battery types for PV applications
Discuss load profiles and modes of operation, including: peak load shaving, time-of-use, zero-sell, self-consumption prioritization, demand-side management
Complete a load estimate for different system types and for seasonal loads; evaluate electrical requirements of loads
Discuss different overcurrent protection devices and equipment disconnects and when/where they are required
Explain the relationship between real power, apparent power, and reactive power
List features, options, and metering available for different types of battery chargers
List basic commissioning tests which should be completed before and after a system is operating
