How does a SatCon PowerGate Plus PVS-50 208V inverter respond to a distribution system fault?
How does a SatCon PowerGate Plus, Model PVS-50 208V inverter respond to a distribution system fault? How fast does the unit go to zero power output?

Hi. I looked up the Satcon PVS-50 on the web and it's UL listed for UL 1741.
With regard to anti-islanding, all UL listed inverters are required to disconnect from the grid if power deviates by some percentage in any direction (frequency, voltage).
In all the standards I've seen the requirement is never more than 2 seconds (2 cycles) in the US. Most ulitities require a wait time of 1 minute before reconnection after operating conditions at met again. All US UL listed inverters I've seen are set from the factory to reconnect after 5 minutes.
In the UL tests I've seen, most inverters take 50-80 miliseconds to disconnect.
So, the PVS-40 should disconnect from 208V service, unless it detects 183 - 229 VAC, in less than 1 second.
Maybe someone can post the UL test data for the PVS-50?
