F23 AI Over
Frequency
Automatic Over-frequency anti-
islanding, caught by the
AC qualification limit.
No action required. The
inverter stops selling and
disconnects from the grid.
When the fault clears, a
five-minute timer begins
counting down. The inverter
does not sell again until grid
voltage and frequency are
within range for five minutes.
F24 AI Under
Frequency
Automatic Under-frequency anti-
islanding, caught by the
AC qualification limit.
See F23.
F25 AI Over
Frequency
Automatic Over-frequency anti-
islanding.
See F23.
F26 AI Under
Frequency
Automatic Under-frequency anti-
islanding.

F29 AI L1L2 Over
Voltage
Automatic Over-voltage anti-
islanding fault, caught by
the qualification limit,
voltage difference
between L1 and L2.
See F23.
F30 AI L1L2 Over
Voltage
Automatic Over-voltage anti-
islanding, fast
disconnect, 270 V.
