10 Installation 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
common connection.
All PWRcell inverters are shipped from the factory in
compliance with all UL1741 requirements, including
IEEE1547. If permission to operate (PTO) is dependent
on compliance to a specific utility standard, follow the
steps covered in Installer Configuration Tool section in
this manual.
Voltage Trip Thresholds
See Table 3-2 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.
Frequency Trip Thresholds
See Table 3-2 for the default fixed frequency trip set-
points. All over frequency and under frequency trip condi-
tions result in a 300-second restart delay time after the
trip threshold has been exceeded for the listed number of
cycles.
*Value of 999 indicates a disabled threshold for voltage trips
**Value of zero indicates a disabled threshold for frequency trips
