We stilll have a few seats remaining for the PVA Live course at the 2024 NABCEP Conference ☀️!

About this course

The 2023 National Electrical Code (NEC) was first adopted in January 2023 and will be adopted by many different states at different times. In this class, Sean White and Bill Brooks explain the NEC in a way that is as fun as possible for a large, very technical book. This course is jam-packed with 2023 NEC insight, interpretation, and comparison to past versions.

It is recommended that students also purchase the book PV and the NEC by Sean White and Bill Brooks. This book has been updated for the 2023 NEC. It can be purchased directly from the publisher or other online book sellers. 

It also may be helpful for you to get a copy of the 2023 NEC, which you can access digitally online for free.

Module 3 Energy Storage Systems (706) and Interconnections (705)

If you are studying for the NABCEP exams, you do not need to focus as much on ESS. ESS is a hot topic and very important in real life, which is more important than what NABCEP puts on exams. This is subject to change and will be big news here when it does. Article 706 ESS was new in the 2017 NEC and much of it came out of Article 690. It was originally meant to replace Article 480 Storage Batteries, however 480 was kept in the NEC. Article 690 points us to 706 when using energy storage systems and not 480. Different AHJs interpret this differently and the NEC can sometimes contradict itself as we will learn. Article 705 Interconnected Power Production Sources is very important for both PV and ESS and is definitely a part of the NABCEP certification exams.
