It seems in Ireland there's a requirement to have the DC side of a PV setup be disconnected in the event of a fire
Most of the automatic disconnects I've seen will cut the DC connection if there is a grid AC failure (from the firefighters switching the house's power off at the meter box)
This doesn't seem to work well with anti islanding since it would disable your PV in a grid failure
I'm wondering is there a way to accomplish a firefighter disconnect while still having power in a grid failure. I'm thinking perhaps a firefighter switch in the meter box which will open relays to isolate the PV, battery and Quattros would be suitable
Does anyone have any experience in this area?
