Solar Training - Solar Electric Design (Battery-Based)

Course ID: PV203Status: Completed
Duration: 5 Days
Start Date May 5, 2014
End Date: May 9, 2014
Instructor: Kelly Larson
Tuition: $995.00


Category: Solar Training (Electric)

Course Description: Apply the National Electrical Code (NEC) to battery-based systems in this in-person solar training course to ensure safe, code-compliant design and installation. This course will build upon the core concepts from PV101, with a specific emphasis on battery-based system design.  Students will work through step-by-step design process for battery-based applications, including stand-alone (off-grid), grid-tied with battery back-up, and hybrid systems. 

Topics such as load analysis, component selection, battery safety, voltage drop, and commissioning procedures will be presented.  In addition to sizing exercises and calculations, students will explore additional design considerations unique to battery-based systems. 

This course is ideal for people looking to design and install battery-based systems, and for solar professionals who have been working in the grid-direct market and need to learn about battery-based systems in preparation for the NABCEP Solar PV Installer Certification Exam.

Prerequisites:  PV101 or PVOL101 (or PV D&I or Grid-Tied PV prior to January 2010)


This PV203 in-person course includes an online component, PV203 PREP that must be completed prior to coming to the in-person PV203: 


Students receive access information shortly after registration for PV203.  PV203 PREP - Battery Based Systems Fundamentals enhances students’ learning experience and allows time to cover more information in the in-person PV203 course.  

PV203 PREP must be completed before participating in a PV203 workshop.  PV203 PREP is an online, on-demand instructorless course, which will require approximately 18 hours to complete and will help you be successful in our PV203 workshop. This PREP course is included in the tuition price of PV203. 

If you are just looking for enough battery-based system information to prepare for the NABCEP exams or SEI's PV301L Battery Based Lab, but will not be working extensively with Battery Based systems,  you may be interested in just taking our shorter, 18 hour, instructorless, on-demand PV203 PREP - Battery Based Systems Fundamentals Online Course, without the full PV203.  

Course materials:  2011 National Electrical Code Book.  You will recieve your copy on the first day of the course. Included in tuition price of the workshop. 

Students who complete the workshop will be able to perform the following:
•    Diagram a battery bank in series and parallel configurations 
•    Identify the proper safety protocols for working with batteries 
•    Draw a three-line schematic of a residential battery-based system, including the array, controller, batteries, inverter, disconnects, overcurrent protection, and grounding (including the equipment grounding conductors, ungrounded conductors, grounded conductors, the grounding electrode(s), and the system grounds)
•    List the pros, cons, and applications of hybrid and AC and DC coupled systems 
•    Define depth of discharge, days of autonomy, equalization, and efficiency of a battery
•    Create a maintenance schedule for batteries
•    Calculate maximum charge rates for batteries and determine state of charge
•    Identify the pros and cons of using valve regulated lead acid (VRLA) verses flooded batteries in specific system designs
•    Specify either a PWM or MPPT charge controller depending on system parameters
•    Specify a battery-based inverter given electrical load and surge requirements
•    Evaluate a client’s electrical load and size a stand-alone system (including inverter, controller, battery bank, and array) 
•    Perform sizing calculations for their battery-based system
•    Size a grid-tied with battery back-up system (including inverter, controller, battery bank, and array)
•    Calculate and diagram appropriate series fusing for a battery-based system
•    Identify appropriate disconnect and overcurrent protection placement
•    Provide all NEC required labeling for a battery-based system
•    List the order of commissioning and decommissioning, as well as potential safety hazards, for battery-based systems

Contact Training Hours (shown on Record of Completion): 

  • 1 week in-person workshop = 40 hours plus 18 hours for PV203 PREP = 58 contact training hours.

NABCEP Training Hours: 
•    PV Installer Certification Requirements: This hybrid course counts for 58 advanced training hours total.
•    PV Installer Recertification Requirements: This course counts for the following:

  • 6 NEC (Code Based) Hours
  • 6 Job Task Analysis Hours
  • 6 Non-Technical Hours

•  PV Technical Sales Recertification Requirements: This course counts for 6 Non-Technical/Other Hours

•  Solar Heating Installer Recertification: This course counts for 6 Non-Technical continuing education hours.

Quotes from students in the November 2012 session of PV203:

  • The comradery of the classmates, the exception depth of knowledge of the instructors and their ability to pass it on to you, being as patient as it took for you to understand the concept or topic. In the end it was the instructors that stood out the most. They were great at building your confidence. 
  • The instructors in the videos really imparted real life experiences into the their presentations. They really brought the course together in a way that PV101 was not able to.
  • As I completed my 4th and final Class for Solar Pro certification, I have to say that I was nothing short of impressed by the quality of presentations, amount of materials presented in nice and organized ways, and instructors' passion for the Solar Industry. I learned more than I expected, and I am looking forward to continued co-oparation with SEI
    Team . Thank you.
  • I am really impressed with how experienced the instructors are and how well the courses are put together. Happy Holidays and I'll see you next year!
