This class will be a small study session type of class with just a few students, so you can get more personalized help. We can move the days around ot make the program just as you need it for you or your company. These are the best classes and are instructor direct. Instructor has ISPQ Master Trainer Certification and is a NABCEP Entry Level provider. This class can provide NABCEP PV credits for the PV Installation Professional Certification.
PV currents flow backwards to the grid and with conditions that can be greater than the current and voltage that the PV is rated for, which leads to tricky calculations that we will simplify in this course. This course is a translation of the NEC into language real people understand. This class will cover the 2011 NEC, including PV ac and dc conductor ampacity calculations, when to and when not to apply the 1.56 correction factor on PV dc circuits, voltage drop (rise) calculations, combiner and recombiner fuse size calculations, when fuses are not required in a combiner, grounding and bonding, voltage temperature calculations, transformerless inverters, bipolar inverters, power factor correction inverters, the 120% rule in subpanels and some comparisons to the Canadian Electrical Code. PV currents flow from the modules to the grid in a backwards direction causing many differences, such as voltage rise causing higher voltages at the inverter than the grid and higher voltages at the PV than the inverter.
