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.

NEC Overview

Before we dive deep into NEC articles specific to PV and ESS, we are going to get more familiar with the rest of the NEC, from a PV and ESS point of view. We will save the Bill Brooks segments for the deep dives into the more advanced material.

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

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.

In 2025 there seems to be a lot of negative with PV from the outside. But I assure you. It's the future. Utilities are not always on the customer side and dinosaurs will die. Power to the people baby

I love the course. It's a great way to stay abreast of all the code changes and the reason for the code changes. I always feel more confident after I've reviewed the course materials.

I take all my PV/ESS related courses here. I find Sean and Bill's communication style light, informative, and highly effective. I always leave their courses with a much better understanding of the material. I feel fortunate to have access to such high level experts. Thank you both!
