In preparation of submitting a permit application for the PV system I'm constructing I will need a rapid shutdown switch of some kind
-OR-
"IF ANOTHER MEANS OF RAPID SHUTDOWN IS NOT PRESENT, PROVIDE A ROOFTOP DC DISCONNECT * @ ROOF WITHIN 3’ OF PV ARRAY ALONG ACCESS PATHWAY PER HAYWARD FIRE ORDINANCE."
After looking around the rapid shutdowns available are ~$800-$1000. I'm not sure how much a DC Disconnect would run. At the price point of the shutdown switch at least would it be more worthwhile to explore micro-inverters instead? If so, then how to do those play with ALL-in-1 inverter controllers like the LV6548s I have?
