The circuit requirement for photovoltaic (PV) systems are covered in Part II of the 2017 National Electrical Code (NEC). To correctly size the overcurrent protection [Sec. 690.9] and conductors, you must first determine the maximum voltage [Sec. 690.7] and the maximum current [Sec. 690.8].
This suggested practices manual examines the requirements of the National Electrical Code (NEC) as they apply to photovoltaic (PV) power systems.
The way Code treats systems over 1,000V has changed. We are now referred to 690.31(G), a new addition entirely, for the requirements for these higher voltage systems. In the previous Code version, there was a reference to 1,500Vdc systems indicating that they were exempt from Parts II and III in Article 490 when not installed on or in buildings
