But isn’t the whole concept of RS to prevent the energizing of say a metal roof?The inverter sees a ground fault or ark fault. Trips off line, the RS activate and now it’s less than 80v. Isn’t that what it’s supposed to do?What is the purpose of grounding the metal roof?JayOn Jun 6, 2023, at 10:09

How about extending your bonding wire out to the adjacent panels in roof areas with S5 clamps and attaching a ground lug to each instead of an L foot? I know it sounds a bit ridiculous, but an inexpensive and easy solution?Michael D NelsonMD Electric & Solar, Inc.707-684-0064 mobile707-884-1862
