Description Solution
Vdc1 overvoltage Orange, 6 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.
Vdc2 overvoltage Orange, 6 Overvoltage in DC input number 2
Idc1 overcurrent Red, 1 Overcurrent in DC input number 1 Check the installation in the DC part.
If the error persists, contact the Technical Service.
Idc2 overcurrent Red, 1 Overcurrent in DC input number 2
Vbus overvoltage Red, 2 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.
Inst. Overvolt. Vac Orange, 2
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 Orange, 2
AC output voltage out of the
defined range
Inst. Overcurr. Iac Red, 1
Instantaneous overcurrent at the
AC output
Check the installation in the AC part.
If the error persists, contact the Technical Service.
Iac out of range Red, 1
AC output current out of the
defined range
Fac out of range Orange, 3
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/DC pwm fault Red, 3 Firmware fault in the DC/DC phase
Check the installation in the DC and AC part.
If the error persists, contact the Technical Service.
DC/AC pwm fault Red, 3
Firmware fault in the DC/AC
conversion phase
DC/DC hw fault Red, 3
Hardware fault in the DC/DC
phase
DC/AC hw fault Red, 3
HW fault in the DC/AC conversion
phase
Temperature alarm Orange, 4
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. Cool the room where the
inverter is installed.
Fatal error Not applicable Not applicable Not applicable
Manual stop
Orange,
constant
The inverter has been manually
stopped.
Start the inverter by means of the display.
Hardware error Red, 1
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 Orange, 5 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
Orange,
constant
Inverter shutdown due to firmware
load
Normal shutdown due to inverter firmware update.
