6 FAQs about [Photovoltaic energy storage control code]

What are the key codes for solar PV & battery storage?

This article highlights the key codes and some of the top sections contractors working with solar PV and battery storage should be familiar with. The most common code system designers, installers, and inspectors refer to for PV and ESS systems are NFPA 70, or the National Electrical Code ( NEC ).

What NFPA codes are used for PV & ESS systems?

The most common code system designers, installers, and inspectors refer to for PV and ESS systems are NFPA 70, or the National Electrical Code ( NEC ). PV systems have requirements that span multiple Code articles, so technicians need to navigate throughout the NEC to install code-compliant PV and ESS systems.

What is a solar Code Article?

Another Code article that will be nearly universally referred to during the design and installation of PV systems is Article 705, Interconnected Electric Power Production Sources. This article covers the requirements for all power production sources interconnecting together, so it isn’t unique to solar.

Are PV systems regulated by fire codes?

Outside of the NEC, technicians need to be cognizant of the fire codes their jurisdictions enforce and how PV systems are regulated within those codes. The most common fire codes are NFPA 1, Fire Code and ICC’s International Fire Code (IFC). These codes typically impact the physical layout of PV modules on the roof of a building.

Which code articles Impact PV installations?

Additional Code articles that impact PV installations include 691, Large-Scale Photovoltaic (PV) Electric Supply Stations; Article 706, Energy Storage Systems; Article 480, Storage Batteries; and the entirety of Chapters 1 through 4, with Article 250 and Article 300 being commonly referenced.

How do fire codes affect energy storage systems?

Fire codes also regulate the use and location of energy storage systems (ESS). Chapter 15 of NFPA 855 provides requirements for residential systems. In particular, ESS spacing, unit capacity limitations, and maximum allowable quantities (MAQ) depending on location. PV systems also have structural requirements and codes associated with them.
