CAUTION
Troubleshooting for the inverter must be performed by qualified personnel in compliance with the general safety
instructions in this manual.

Alarm
Description
Solution
Vdc1 overvoltage
Overvoltage in DC input number 1
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.
Idc1 overcurrent
Overcurrent in DC input number 1
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.
If the error persists, contact the Technical Service.
Vbus overvoltage
Overvoltage in the bus
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.
If the error persists, contact the Technical Service.
Inst. Overcurr. Vac
Instantaneous overvoltage at the
AC output
Check the connections of the AC side. Check that the voltage of the
electricity grid is within range.
Vac out of range
AC output voltage out of the
defined range
Inst. Overcurr. Iac
Instantaneous overcurrent at the
AC output
Check the connections of the AC side. Check that the voltage of the
electricity grid is within range.
Iac out of range
AC output current out of the
defined range
Fac out of range
AC grid frequency out of the
defined range
Check the connections of the AC side. Check that the frequency of
the electricity grid is within range.
DC/AC pwm fault
Firmware fault in the DC/AC
conversion phase
Check the installation in the DC and AC part.
If the error persists, contact the Technical Service.
DC/AC hw fault
HW fault in the DC/AC conversion
phase
Temperature alarm
Temperature out of operating
range
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. Ensure the inverter's ambient
temperature is within the operating range.
Fatal error
Fatal error
Disconnect the DC and AC inverter. Wait until the LEDs go off and
re-connect. If the problem persists, contact the Technical Service.
Manual stop
The inverter has been manually
stopped.
Start the inverter by means of the display.
Hardware error
The inverter displays a hardware
error
Disconnect the DC and AC inverter. Wait until the LEDs go off and
re-connect. If the problem persists, contact the Technical Service.
Residual current
Residual current out of range
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.
FW update
Inverter shutdown due to firmware
load
Normal shutdown due to inverter firmware update.
Grid consumption
Grid consumption power out of the
permitted range
This may be due to a low irradiance level. Otherwise, check the PV
array.
Low pow. PV conn.
The generated power in the PV
array is not sufficient to connect to
the AC grid
Fault elect. supply
Fault in power supply to the
electronic circuit boards
Check the correct connection of the DC cables. Open the unit and
check the correct connection of the control board.
