Anyone who has worked with the National Electrical Code (NEC®) knows that abiding by its requirements often means not just understanding what the code says, but grasping why it says it.

SEI’s new on-demand course Comprehensive 2026 NEC® Requirements for Electrotech: PV, ESS, EVs, PCS, and More (CE549) was designed with that in mind — developed and presented by Solar Tech Collective, whose team members serve as active voting members on panels responsible for the NEC articles governing PV, energy storage, EV charging, and power control systems. That means the people teaching this course were in the room when these requirements were written. The result is training that goes beyond compliance checklists and into the reasoning, interpretation, and real-world application that doesn’t just satisfy code requirements, but helps produce installations that are safe, efficient, and built to last.

What the Course Covers

The 2026 edition of the NEC brings significant changes across the articles that affect solar and energy storage design and installation. CE549 covers the full scope through six modules and approximately 80 short video lectures, each paired with knowledge check questions, now available on demand through SEI’s online training platform. Topics covered include:

  • Significant changes across the NEC impacting PV, energy storage, EVs, and power control systems
  • Article 690: Solar Photovoltaic (PV) Systems
  • Article 691: Large-Scale PV Electric Supply Stations
  • Article 705: Interconnected Electric Power Production Sources
  • Article 706: Energy Storage Systems
  • Article 480: Stationary Batteries
  • Article 130: Energy Management Systems
  • Article 702: Optional Standby Systems
  • Article 625: Electric Vehicle Power Transfer SystemsArticle 710: Stand-Alone Systems
