E056
Over Temp. (from
external box)
Excessive temperature mea-
sured inside the inverter’s wiring
box:
High internal temperature.
This error relates to the tempera-
ture measured on external boxes.
Check that the inverter is not exposed to direct
sunlight. Wait for the temperatures to which the in-
verter is exposed to return to the operating range
and for the inverter to cool down.
If the problem persists (once the ambient tempera-
ture has returned to the range), contact customer
service.
E057
Vbulk reading error
Input voltage (Vin) higher than
booster voltage (Vbulk):
The error occurs if the input volt-
age exceeds the Bulk voltage
(voltage on the DC-DC circuit in-
side the inverter)
Measure the input voltage inside the inverter
with a voltmeter. If it is higher than the maximum
voltage of the operating range, it is necessary to
check the configuration of the PV array.
If the voltage has also exceeded the maximum in-
put threshold the inverter could be damaged.
If it is lower than the maximum voltage of the op-
erating range, the alarm is caused by an internal
malfunction and it is necessary to contact customer
service.
E058
Pin vs. Pout check
error
The error occurs if the difference
between the measured value of
input power and that of output
power is greater than the limit im-
posed internally to the inverter.
Error inside the inverter that cannot be checked ex-
ternally. If the problem persists (after switching the
inverter off and then on again), contact customer
service.
W001
Sun Low
(Low input voltage
during switch-on of
the inverters)
Insufficient sunlight. Wrong con -
figuration of the PV array or a
configuration “at the limit” as re -
gards the minimum input voltage
of the inverter.
Check the inverter input voltage.
If it does not exceed the Vstart, check that there is
sufficient sunlight and that the composition of the
system is correct. If it exceeds the Vstart, contact
customer service.
W002
Input UV
(Low input voltage
during switch-off)
Insufficient sunlight Wrong con -
figuration of the photovoltaic ar -
ray or a configuration “at the limit”
as regards the minimum input
voltage of the inverter.
Check the inverter input voltage.
If it does not exceed the Vstart, check that there is
sufficient sunlight and that the composition of the
system is correct. If it exceeds the Vstart, contact
customer service.
W003
Grid Fail
Grid Fail (grid volt-
age parameters
outside the limits)
This error warning appears dur-
ing normal operation of the in-
verter when the grid parameters
fall outside the limits set by the
grid company.
No grid voltage (after the warn-
ing, the inverter goes on “No
Vac”) Unstable grid voltage
(downwards and upwards) Un-
stable grid frequency.
Check the grid voltage on the inverter. If absent,
check for the absence of grid voltage on the sup-
ply. If the voltage tends to rise (when the inverter
is connected), it means there are high line or grid
impedances. Check the grid voltage on the supply
as well; if it is high, it means there is high grid im-
pedance. In this case, ask the grid company to ad-
just the grid voltage. If the grid company authorizes
a change to the inverter parameters, arrange the
new limits with the customer service.
If the voltage at the supply point is much lower than
that measured on the inverter, the line must be ad-
justed (inverter- counter). If the grid voltage and fre-
quency fall within the limits (even when the inverter
is connected to the grid), contact customer service.
