Table 3. DC Input Warning and Shutdown
• Unit start up voltage (Lo setting): > 10.5 +/- 0.3 VDC and < 16.0 +/- 0.3 VDC
• Unit start up voltage (Mid setting): > 11.8 +/- 0.3 VDC and < 16.0+/- 0.3 VDC
• Unit start up voltage (Hi Setting): > 12.2 +/- 0.1 VDC and < 16.0 +/- 0.3 VDC
ote:N
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

AC output short circuit protection
A short circuit may be applied to the AC output continuously during inverter mode without damage to any components. Unit
will shut down within 10 seconds, and display will indicate ‘E03’ with the buzzer beeping @ 1 Hz.
ote:N 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.
