PV Installation Best Practices:

Learn how to do it right with techniques and recommendations from PV experts, as well as basic installation considerations and best practices. Industry-expert tips and techniques will help you minimize risk and deliver a top-notch install, worthy of being inspected by the very best. Reduce installation time and labor, and avoid unnecessary call-backs and red-tags from your AHJ. A fun-filled presentation on residential, commercial, and utility-scale PV systems that will make you groan, gasp, and, at the same time, have some “a-ha” moments. Ideal for PV installers and inspectors, especially for those interested in quality control and risk reduction.

Point of Interconnection

Get insight on the most updated rules-of-the-game for designing the point of interconnection (POI) for a grid-tied PV system according to NEC 2017 (and learn about what may be updated for the next revision of NOM-001-SEDE-2018!). NEC 2017 POI requirements include sections that can greatly benefit your PV designs. In this class we present them through diagrams, examples and calculations in real sizing situations. Learn how to size distribution panels based on PV watts being installed, or understand the limitations in sizing a PV systems according to existing panels; learn how to size panels connected in series and panels for parallel connection of many inverters in large solar farms.

Ground Faults (GF) Troubleshooting and GF Protection Retrofit

Ground faults are unfortunately relatively common, dangerous and difficult to troubleshoot, and are one of the leading causes of downtime in PV systems. Most are caused by oversights during installation, bad raceway design or installation, and other factors that can be reduced or avoided with proper training. In this class we will learn about ground faults, how to avoid them, and how to locate them once fault detection systems trigger an alarm. Following that, we will cover the requirements and options for ground-fault protection in different inverter topologies, and what are the main concerns around ground fault protection blind spots. Finally, we will delve on retrofitting and improving ground fault protection systems in existing PV systems.
