AC Frequency and Voltage Fault Detection
The quality of the power delivered to the utility line must meet or exceed the
requirements as specified in IEEE 1547a. If the utility frequency or voltage shifts outside
the regulatory specified limits, the Inverter will automatically detect the condition and
shutdown. The Inverter is shipped from the factory with a default five (5) minute restart
counter for AC over/under Frequency limit faults and AC over/under voltage limit faults.
