Take a deep dive into National Electrical Code (NEC® 2014) standards as well as other best practices that pertain to designing grid-direct PV systems. The focus in PVOL202 is on residential and commercial-scale systems, but the Code requirements, design parameters, and best practices are applicable to all types and sizes of PV installations. Detailed lessons address requirements for disconnects, overcurrent protection, and wire sizing; interconnection requirements and calculations; grounding, ground-faults, and surge protection; calculations for system sizing, inverter selection, and electrical configuration; ground and roof mount details; and commissioning and performance analysis procedures.PV202 focuses significantly on the National Electrical Code, including interconnection calculations, grounding, workspace clearances, and disconnect and overcurrent protection sizing and considerations.Prerequisites: PV 101 or PVOL101 (or PV D&I or Grid-Tied PV prior to January 2010)
