Power Limitation Messages - ABB PVS-100-TL-B-SY2 Product Manual

- Error code
- Error message Name of Alarm and Cause
- LED status
Error during the automatic check of the string
voltages (only in models with the "fuse-control"
board):
E046
In some inverter models it is possible to carry out the
- Str. test failed
check test of the polarity of the strings connected to
- No LED
the input.
This error signal occurs when, during the test stage,
an inverted string is recorded
E049
Error in the "AC feed-forward" circuit:
- Internal error
Error inside the inverter
- Yellow LED
E051
- Safety mem. Fault Error inside the inverter.
- Yellow LED
Input voltage (Vin) higher than booster voltage
E057 (Vbulk):
- Vbulk reading The error occurs if the input voltage exceeds the
-
Yellow LED Bulk voltage (voltage on the DC-DC circuit inside the
inverter)
Error in the check of Pin vs Pout:
E058 The error occurs if the difference between the
- Internal error measured value of input power and that of output
- Yellow LED power is greater than the limit imposed internally to
the inverter.
Communication error inside the inverter:
E074
The alarm occurs when there are communication
- Internal error
problems between the control devices inside the
- Yellow LED
inverter.
E077
Error in the system configuration:
- Internal Error
Error inside the inverter
- Yellow LED
E078
Riso test error:
- Riso Test fail
Problem detected during the Riso test phase.
- Yellow LED
E079 Incorrect Phases connection
- Wrong Sequence (Only triphase models) The phases have not been
- Yellow LED connected correctly to the AC output
Return current to photovoltaic field:
E084 The error occurs if the input voltage is particularly low
- BackFeed OC
(typically in the evening in conditions of low irradiation)
- Yellow LED and indicates a return current from the inverter to the
photovoltaic panels).

Solution
• Section the inverter and check the polarity of the string(s)
which the inverter has recorded as inverted.
- Once all the strings have been correctly connected, activate
the system once again; the inverter will once again check the
correct polarity of the string inputs at the end of which it will
carry out the checks for the grid connection.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• Error inside the inverter and cannot be checked externally.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• Error inside the inverter and cannot be checked externally.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• It is necessary to measure the input voltage inside the
inverter with a voltmeter.
- If it is higher than the maximum voltage of the operating
range, the alarm is genuine and it is necessary to check the
configuration of the PV generator. If the voltage has also
exceeded the maximum input threshold the inverter could be
damaged.
- If it is lower than the maximum voltage of the operating
range, the alarm is caused by an internal malfunction and it is
necessary to contact customer assistance.
• Error inside the inverter and cannot be checked externally.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• Error inside the inverter and cannot be checked externally.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• Error inside the inverter and cannot be checked externally.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• Error inside the inverter and cannot be checked externally.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
• Invert two of the phases of the network wiring to the AC
terminal block of the inverter.
If the error occurs in the evening or in conditions of low
irradiation, it must not be considered a problem but a
protection intervention for the photovoltaic field.
- If the error occurs with good irradiation conditions, switch
the inverter off and back on again; if the error persists, contact
customer assistance.
The equipment can signal possible output power limitations which may
occur on the basis of:
- settings made by the user
- settings required by the grid standard of the country of installation
- protective devices inside the inverter
