Description
System malfunctions
Grid frequency is outside the limits ("Table 2" in the
appendix)
Grid voltage is outside the limits ("Table 2" in the
appendix)
Average grid voltage is outside the limits ("Table 2"
in the appendix)
The inverter is limiting the output power because the
grid voltage is greater than the threshold set using
the software („VPD‟ function).
The input voltage exceeds the "Maximum no-load
voltage"
No grid voltage present. If the condition persists for
more than 1s, the single phase inverters will switch
off.
Grid voltage or frequency are outside the limits in
the "connection" line of the regulations that envisage
it ("Table 2" in Appendix).
The inverter is limiting the output power according to
the grid frequency („FPD‟ function).
The inverter has interrupted feeding due to the
emergency command received from the grid
operator.
Internal voltage is too high
The internal bulk capacitors are not balanced
Temperature is too high
The inverter does not detect one or more internal
devices
Verification of PV generator isolation resistance was
negative.
Current leakage toward grounding
The inverter has input a direct current on the grid
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
