Fault Type Cause
Automatic Over-frequency anti-
islanding, caught by the
AC qualification limit.
Automatic Under-frequency anti-
islanding, caught by the
AC qualification limit.
Automatic Over-frequency anti-
islanding.
Automatic Under-frequency anti-
islanding.
Automatic Over-voltage anti-
islanding, fast
disconnect, 135 VAC.
Automatic See F27.
Automatic Over-voltage anti-
islanding fault, caught by
the qualification limit,
voltage difference
between L1 and L2.
Automatic Over-voltage anti-
islanding, fast
disconnect, 270 V.
Automatic Over-voltage anti-
islanding, slow
disconnect, 130 V.
Automatic Over-voltage anti-
islanding, slow
disconnect, 130 V.
Automatic Over-voltage anti-
islanding, slow
disconnect, 260 V.
Automatic Under-voltage anti-
islanding, slow
disconnect, 108 V.
Solution
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.
