Learn about the ground reference and isolation requirements for bipolar arrays from the 2017 National Electrical Code (NEC) related to solar photovoltaic (PV) systems and identify the difference between past system and current system designs.
On the shortest Day of the Year Dec 21, at Sunset, we pull a DC Arc from 8 x newly installed 395W solar panels in series (400V). Showing you how important it is to choose the right DC breaker for your Solar, and how easy it is to get killed in ignorance.
