What is an Array According to NEC?

In the realm of electrical installations, clarity and precision are paramount, especially when referring to specific terms outlined in the National Electrical Code (NEC). One such term is ‘array’. According to NEC Article 100, an array is defined as a mechanically and electrically integrated grouping of modules, which includes not only the support structures but also any attached system components.

The Importance of Arrays in Electrical Systems

Arrays play a significant role in solar power systems, serving as a fundamental component in translating sunlight into usable energy. The definition elucidated in the NEC emphasizes the importance of considering all elements involved—modules, inverters, DC-to-DC converters, and associated wiring. This comprehensive understanding ensures that electrical professionals can design systems that are both efficient and compliant with safety standards.

Components of an Array

When reviewing an array, it’s essential to recognize its composite parts. Each module is typically designed to work in unison with its counterparts, enhancing overall performance and functionality. The attached system components, such as inverter(s) and DC-to-DC converters, serve critical roles in optimizing energy conversion. Therefore, knowing the intricacies of these components under NEC Article 100 not only aids in compliance but also fosters innovation in electrical design and installation.
