Description
Proposed action
System malfunctions
„A02 Fac outrange‟
Grid frequency is outside the limits (“Table 2” in the
appendix)
Wait for reconnection.
„A03 Low Vac‟
Grid voltage is outside the limits (“Table 2” in the
appendix)
Check the AC system, contact your energy
distributor.
„A04 High Vac‟
„A05 High avg Vac‟
Average grid voltage is outside the limits (“Table 2”
in the appendix)
„A06 Weak grid‟
The inverter is limiting the output power because the
grid voltage is greater than the threshold set using
the software („VPD‟ function).
„A07 High Vdc‟
The input voltage exceeds the “Maximum no-load
voltage”.
Verify system size.
„A08 No Grid‟
No grid voltage present. If the condition persists for
more than 1 s, the inverter will switch off.
Wait for reconnection.
„A09 Grid anomaly‟
Grid voltage or frequency are outside the limits in
the “connection” line of the regulations that envisage
it (“Table 2” in the Appendix).
Check the AC system, contact your energy
distributor.
„A10 Overfrequen.‟
The inverter is limiting the output power according to
the grid frequency („FPD‟ function).
No action required.
„A11 Emergency‟
The inverter has interrupted feeding due to the
emergency command received from the grid
operator.
Inverter problems
„F01 High V_bulk+‟
Internal voltage is too high.
None, the inverter will restart by itself.
„F03 High V_bulk-‟
„F03 High V_bulk‟
Internal voltage is too high.
1.5kW – 2kW version: Contact technical
assistance.
3kW version: None, the inverter will
restart by itself.
„F04 Bulk balance‟
The internal bulk capacitors are not balanced.
None, the inverter will restart by itself.
„F05 High °C‟
The temperature is too high or the temperature
sensors are faulty.
Check requirements in the Choosing an
installation site paragraph If the inverter
displays the alarm even after a prolonged
shutdown, contact technical assistance.
„F06 Link fail‟
The inverter does not detect one or more internal
devices.
Contact technical assistance.
„F07 Insulat. KO‟
Verification of PV generator isolation resistance was
negative.
Check the system if the problem persists for
a few days.
„F09 GFCI leakage‟
Current leakage toward grounding.
„F08 DC injection‟
The inverter has input a DC current on the grid that
is too high.
Wait for reconnection to the grid.
