Solution
Check the connections of the PV array, ensuring the
series-parallel configuration of the panels is correct,
and that the maximum voltage of the inverter has
not been exceeded.
Check the installation in the DC part.
If the error persists, contact the Technical Service.
Check the connections of the PV array, ensuring the
series-parallel configuration of the panels is correct,
and that the maximum voltage of the inverter has
not been exceeded.
Check the connections of the AC side. Check that
the voltage of the electricity grid is within range.
Check that the AC varistors are not damaged.
Check the installation in the AC part.
If the error persists, contact the Technical Service.
Check the connections of the AC side. Check that
the frequency of the electricity grid is within range.
Check the installation in the DC and AC part.
If the error persists, contact the Technical Service.
This may be normal if the room temperature
exceeds the maximum of the unit. Check the
functioning of the fans. Protect the inverter from
direct exposure to sunlight. Cool the room where the
inverter is installed.
Disconnect the DC and AC inverter. Wait until the
LEDs go off and re-connect. If the problem persists,
contact the Technical Service.
Start the inverter by means of the display.
Disconnect the DC and AC inverter. Wait until the
LEDs go off and re-connect. If the problem persists,
contact the Technical Service.
Check that there are no insulation faults in the PV
array. Check that the stray capacity of the PV array
does not exceed the maximum permitted.
Normal shutdown due to inverter firmware update.
