ALARM
TYPE
SOLUTION
E020
Feeding in a direct
current with a value
higher than the
admitted threshold.
■
Make sure that there is a direct current fed into the grid.
■
If the direct current fed into the grid does not fall within the
permitted range for reasons due to the local grid conditions,
contact the grid operator to request approval for the modifi-
cation to the operating limits.
■
If the direct current fed into the grid it is within the allowed
range, but the alarm persists, contact the technical support
service.
E021
Feeding in a direct
current with a value
higher than the max-
imum instantaneous
admitted threshold.
■
Make sure that there is a direct current fed into the grid.
■
If the direct current fed into the grid does not fall within the
permitted range for reasons due to the local grid conditions,
contact the grid operator to request approval for the modifi-
cation to the operating limits.
■
If the direct current fed into the grid it is within the allowed
range, but the alarm persists, contact the technical support
service.
E022
Converter control
system fault.
■
Switch off and restart the system.
■
Refer to the sections “System switching off” and “System
switching on”
■
Should the problem persist, contact our technical support
service.
E023
DC overcurrent.
■
Check the sizing and connections to the DC inputs of the
system.
■
Refer to the section “Electrical connections”.
■
If the problem persists, contact the technical support
service.
E024
DC overcurrent.
■
Check the sizing and connections to the DC inputs of the
system.
■
Refer to the section “Electrical connections”.
■
If the problem persists, contact the technical support
service.
E025
Loss of isolation of
the PV
generator.
■
Check the DC lines leakage to ground.
E026
DC voltage out of
range.
■
Immediately disconnect the system from the photovoltaic
generator as it could be damaged.
■
Check the sizing of the system.
■
Check the noload voltage of the photovoltaic generator.
E027
BATTERY overcurrent.
■
Check the sizing and connections at the BATTERY inputs.
■
Refer to the section “Electrical connections”.
■
If the problem persists, contact the technical support
service.
E028
Battery not
recognized.
■
Check the connections and polarity at the BATTERY inputs.
■
Check the battery voltage and make sure it is within the
limits allowed for operation.
■
Refer to the section “Electrical connections”.
■
If the problem persists, contact the technical support
service.
