1.
Unit will shut down instantly and restart automatically if voltage returns to less than 15.5V within 30 seconds
2.
If DC voltage is not less than 15.5V within 30 seconds, unit will require manual reset by power button
3.
Unit will shut off instantly if DC voltage drops below 10V regardless of settings
4.
Unit will shut off if DC voltage is below shutdown for 10 seconds
5.
Unit will shut off if DC voltage is below shutdown for 90 seconds
6.
Unit will shut off if DC voltage is below shutdown for 2 minutes

Manual reset is required to restart Inverter after AC Overload or Short Circuit shutdown. System will automatically
reset AC Overload or Short Circuit shutdown error when utility is available. The supplemental protector or the branch
protection specified in the Installation Guide should be open under bypass short circuit output condition.
