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 Generac PWRcell Inverters are shipped from the fac-

tory in compliance with all UL1741 requirements, includ-

ing IEEE1547. If your installation requires compliance to

a dif

ferent standard, such as UL1741SA, contact the

nearest Independent Authorized Service Dealer (IASD)

or Generac Customer Service at 1-888-436-3722 (1-888-

GENERAC), or visit www.generac.com for assistance.

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.
