I took this course to see if it would be a good fit for our O&M team annual training. The course is absolutely great and will benefit any PV technicians that need more clarity around megger testing and troubleshooting tips for isolating different system types. Highly recommend!

This class upped my game with knowledge and ability to use digital multimeter (DMM) and Insulation Resistance tester (IRT) to systematically located faults (safely). It also increased my confidence to solve problems that were too overwhelming before. Now I have a strategy and know what to do to tackle these problems. When I was a designer and installer I did not encounter the same problems that I now face all the time as an O&M technician. The PV industry is maturing and we are all having to learn to fix aging systems whether we like it or not (as they are probably on our own houses if not our customers' and under warranty) This course--especially the trouble shooting flow chart!--has really helped me get a handle on solving these problems.
