Internal fan failure
Restart the inverter. If the fault still exists,
contact your dealer.

DCI error
14-01
DCI error of R-phase
Check whether the inverter and PV panel are
grounded reliably. Power off the inverter for 5
minutes and then power it on again. If the fault
still exists, contact your dealer.

AC voltage
error
31-01
One-level under-voltage
of AC power
1. If the fault occurs occasionally, it may be
caused by momentary abnormality of the
power grid.
The inverter will resume normal operation
when the power grid gets back to normal.
2. If the fault occurs frequently, check whether
the power grid is connected properly.
31-02
One level over-voltage of
AC power
31-03
No AC voltage
Check whether the AC power is connected
properly.
31-04
Two-level under-voltage
of AC power
1. If the fault occurs occasionally, it may
be caused by momentary abnormality of the
power grid. The inverter will resume normal
operation when the power grid gets back to
normal.
2. If the fault occurs frequently, check
whether the power grid is connected properly.
