What is a requirement for microinverters according to Article 690?

Microinverters are designed to convert DC electricity from solar panels into AC electricity at the module level, and they are subjected to the same safety and performance standards as larger inverters. Article 690 of the National Electrical Code outlines various requirements for solar photovoltaic systems, ensuring that all inverters, regardless of size, are compliant with safety and operational regulations.

By adhering to the same requirements as larger inverters, microinverters ensure consistency in safety measures, performance capabilities, and compatibility with the overall grid and electrical system. This standardization helps to facilitate installation and maintenance while ensuring that the devices operate efficiently within the expected parameters.

The other options do not reflect the necessary code requirements for microinverters. Installing them at ground level may not always be practical or safe, and they do not require a separate grounding system distinct from other components of the solar installation. Additionally, the notion that they can be installed without special considerations disregards the importance of adhering to code requirements for safety, efficiency, and reliability.
