I don’t have a copy of the IEEE governing anti-islanding..
my question is testing. I will pull the power to make sure the inverter shuts off in less than 2 seconds. When I restore power I will time the inverter to see when production restarts. 5 minutes is my pass time.
What, or is there, a cutoff for the 5 minute to resume production test.
I’ve heard that all PV less than 10kW doesn’t have to meet this requirement, but I can’t seem to find any information on it.
IEEE 1548.1?
UL 1741?
I had a small (4.5kW) system with string inverters and they resumed production almost immediately.
