Table 24 (Continuation): Alarm messages description�
Alarms
Leakage current
Description
Leakage current exceeds limit.
Actions
Residual current monitor has detected a current higher than the maximum limit.
High residual currents are an electrical safety hazard.
Check the safety of the installation, both the PV panels side and the grid and AC-
Out side, and fix any insulation defect that are detected.
If the installation shows no defect, and his alarm remains activated, contact Tech-
nical Service.
Heatsink temperature
Description
Heatsink temperature over maximum allowable temperature.
Actions
Check that the heatsink is not blocked, and that the installation meets the require-
ments for a proper cooling.
Battery calibration error
Description
The battery calibration process could not be correctly completed.
Actions
Check that there are no electrical network connection problems. Repeat the bat-
tery calibration process after verifying this point.
Calibration error
Description
Leakage current monitor calibration error.
Actions
Restart the inverter, unplugging all supplies (AC, battery). If the inverter keeps fail-
ing, contact Technical Service.
Daily calibration control
Description
Daily leakage current monitor calibration failed.
Actions
Unplug the inverter from the grid, and plug it in again, to force a residual current
monitor calibration. If the inverter keeps failing, contact Technical Service.
Neutral-earth voltage
Description
There is voltage between Neutral and Earth.
Actions
Check for proper wiring of AC grid and Earth connections.
Check for proper connection of the Eart terminal of the installation.
Insulation resistance
Description
Insulation resistance of PV panels exceeds set value.
Actions
Check that the PV panels are in good conditions and measure their ground insu-
lation resistance.
Check the inverter insulation resistance configuration.
Insulation monitor adjustment
Description
Insulation resistance monitor error.
Actions
Check the inverter insulation resistance configuration.
PV panel current
Description
PV panels current over maximum allowable current.
Actions
Check that the PV panels are in good conditions.
Open the PV switch, and restart the inverter, closing the PV switch.
If the inverter keeps failing, contact Technical Service
PV panel voltage
Description
PV panels voltage over maximum allowable voltage.
Actions
Check that the maximum PV string voltage is not higher then the maximum allow-
able voltage.
Change the PV panels string configuration to meet inverter specifications.
