Grid frequency is outside the limits ("Table 2" in the
„A02 Fac outrange‟
appendix)
„A03 Low Vac‟
Grid voltage is outside the limits ("Table 2" in the
appendix)
„A04 High Vac‟
Average grid voltage is outside the limits ("Table 2"
„A05 High avg Vac‟

The inverter is limiting the output power because the
„A06 Weak grid‟
grid voltage is greater than the threshold set using
the software („VPD‟ function).
The input voltage exceeds the "Maximum no-load
„A07 High Vdc‟
voltage"
No grid voltage present. If the condition persists for
„A08 No Grid‟
more than 1s, the single phase inverters will switch
off.
Grid voltage or frequency are outside the limits in
„A09 Grid anomaly‟
the "connection" line of the regulations that envisage
it ("Table 2" in Appendix).
The inverter is limiting the output power according to
„A10 Overfrequen.‟
the grid frequency („FPD‟ function).
The inverter has interrupted feeding due to the
„A11 Emergency‟
emergency command received from the grid
operator.
„F01 High V_bulk+‟
„F02 High V_bulk-‟
Internal voltage is too high
„F03 High V_bulk‟
„F04 Bulk balance‟
The internal bulk capacitors are not balanced
„F05 High °C‟
Temperature is too high
The inverter does not detect one or more internal
„F06 Link fail‟
devices
Verification of PV generator isolation resistance was

negative.
„F09 GFCI leakage‟
Current leakage toward grounding
The inverter has input a direct current on the grid
„F08 DC injection‟
that is too high

Proposed action
Wait for reconnection
Check the AC system, contact your energy
distributor
Verify system size.
Wait for reconnection
Check the AC system, contact your energy
distributor
No action required
None, the inverter will restart by itself.
Wait for the inverter to cool down, check
requirements in the
installation site paragraph
Contact technical assistance
Check the system if the problem persists for
a few days. On 4.6~6kW inverters, verify the
input configuration according to the chapter
CONFIGURING THE DC INPUTS.
Wait for reconnection to the grid
