Installation and Owner’s Manual for Generac PWRcell Inverter
Voltage and Frequency Trip Thresholds
This unit or system is provided with fixed trip limits and shall not be aggregated above 30 kW on a single point of com
-
mon coupling.
All PWRcell Inverters are shipped from the factory in compliance with all UL 1741 requirements, including IEEE 1547.
If permission to operate (PTO) is dependent on compliance to a specific utility standard, follow the steps covered in the
Set Inverter Grid Compliance (optional)
section in this manual.
Voltage Trip Thresholds
See
for the default fixed voltage trip setpoints. All over voltage and under voltage trip conditions result in a
300-second restart delay time after the trip threshold has been exceeded for the listed number of cycles.
The inverter is disconnected from the grid during this 300-second delay.
Frequency Trip Thresholds
See
for the default fixed frequency trip setpoints. All over frequency and under frequency trip conditions
result in a 300-second restart delay time after the trip threshold has been exceeded for the listed number of cycles.
The inverter is disconnected from the grid during this 300-second delay.
*Value of 999 indicates a disabled threshold for voltage trips.
**Value of zero indicates a disabled threshold for frequency trips.
