Location and Compliance

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)

Voltage Trip Thresholds

See Table 3-3 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 Table 3-3 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.
