IMPORTANT SAFETY INSTRUCTIONS
This manual contains important safety instructions that must be fol-
lowed during installation and maintenance of the equipment.
SAVE THESE INSTRUCTIONS!
This manual must be considered as an integral part of the equipment,
and must be available at all times to
everyone who interacts with the equipment.
The manual must always accompany the equipment,
even when it is transferred to another user.
Operators are under an obligation to read this manual and strictly
follow the instructions given in it,
because Power-One cannot be held responsible for damage caused
to people or property, or for damage to the equipment,
if the conditions described below are not complied with.
The customer is under an obligation to keep the industrial secret,
and therefore the following documentation and its annexes
non may not be tampered with or modied, reproduced or transferred to
third parties, without the authorization of Power-One.

1 - Introduction and general information
Conditions of warranty and supply
Warranty conditions are described in an appropriate certicate
supplied with the equipment. Moreover, the warranty conditions are
understood to be valid if the Client observes what is described in this
manual; any conditions deviating from those described below must be
explicitly agreed upon in the purchase order.
Power-one declares that the tool complies with legal provisions in force in the European
Economic Community and releases statements of compliance (may be consulted on
the www.power-one.com website or by sending a request to Service Power-One).
Exclusions from the supply
Power-one declines any responsibility in case standards for correct installation are not
adhered to and it is not liable for systems upstream or downstream of the equipment
supplied by it.
It is absolutely prohibited to make modications to the equipment.
The Customer is entirely responsible for any modications made to the system.
It is not possible to provide the multitudes of installations and environments
in which the tool will be installed; for this it is necessary to checked for:
adequate spaces, adapted to accept the tool; air noise produced as a
function of the environment; any conditions of ammability.
Power-one CANNOT be held responsible for defects or malfunctions
as a result of: improper use of the tool; alterations due to transportation
or special environmental conditions; lack of or improper maintenance;
tampering or poor repairs; use or installation done by non-qualied
people.
Power-one CANNOT be held responsible for disposal of: displays,
cables, batteries, accumulators etc. It is necessary that the Client
provides, according to standards in force in the country of installation,
disposal of such substances that are potentially harmful to the
environment.

Field of use, general conditions
Power-One accepts no liability for damage of any kind that may arise
from incorrect or careless operations.
The equipment must not be used for uses that do not fall within the intended eld of
use. The equipment MUST NOT be used by inexperienced staff, or by experienced
staff to carry out operations on the equipment that are not in accordance with what is
described in this manual and in the attached documents.
Intended or allowed use
This equipment is a multi-string inverter designed to:
transform a direct electric current (DC)
coming from a photovoltaic generator (PV)
into an alternating electric current (AC)
Suitable for being fed into the national grid.
Limits of the field of use
The inverter can be used only with photovoltaic modules that do not require one of the
poles to be grounded.
The operating current dispersed during normal operation must not exceed the limits
specied in the technical specications.
Only one photovoltaic generator can be connected to the input of the inverter (do not
connect batteries or other sources of power supply)
The inverter can be connected to the electricity grid in qualied countries only.
The inverter can be used only if all the technical characteristics are observed.
Improper or disallowed use
THE FOLLOWING ARE STRICTLY FORBIDDEN:
• Installing the equipment in environments with particular ammability conditions or in
adverse or disallowed environmental conditions (temperature and humidity)..
• Using the equipment with the safety devices not working or disabled.
• Using the equipment or parts of the equipment by connecting it to other machines or
equipment, unless expressly provided for.
• Modifying the operating parameters that are not accessible to the operator and/or
parts of the equipment to vary the performance or change its insulations.
• Cleaning with corrosive products that may corrode parts of the equipment or gener-
ate electrostatic charges.
• Using or installing the equipment or parts of it without having read and correctly in-
terpreted the contents of the operating and maintenance manual.
• Warming or drying rags and clothes on parts at temperature. Besides being danger-
ous, this would compromise the ventilation and cooling of the components.

General conditions
The description of the characteristics of the equipment allows its main
components to be identied, to rene the technical terminology used in
the manual.
The Characteristics chapter contains information about the models, the
composition of the equipment, the characteristics and technical data, the
overall dimensions and the identication of the equipment.
This manual should be read in chronological order as established by the manufacturer
and the reader assumes responsibility for failure to do so. All the information is
given considering each time that the information of the preceding chapters has been
acknowledged.
In some cases, there may be a need to separately document the
operation of the software or attach supplementary documentation to this
manual for more qualied professional persons.

Characteristics 2
Models and range of equipment
The specic models of multi-string inverter that this manual is about are
divided into two groups according to the maximum output power (20 kW
or 27.6 kW).
For inverters of equal output power, the variant between the various
models is the layout of the wiring box 02.
The choice of model of inverter must be made by a qualied technician who knows
about the installation conditions, the devices that will be installed outside the inverter
and possible integration with an existing system.

Identification of the equipment and the manufacturer
The technical data shown in this manual do not in any case replace
those shown on the labels attached to the equipment.
The labels attached to the equipment must NOT be removed, damaged, dirtied, hid-
den, etc.
N.B. The labels must NOT
be hidden with objects and
extraneous parts (rags, boxes,
equipment, etc.); they must be
cleaned regularly and kept visible
at all times.

Characteristics 2
In addition to the label showing the specications of the inverter, there
are two part identication labels for the inverter and wiring box.
These labels list the following information:
If the service password is required, please use the details shown on the top label (in-
verter)

Efficiency curves
The equipment was designed in compliance with energy conservation
standards, to avoid waste and unnecessary leakage.
The manufacturer has taken into due consideration the current energy
saving standards in Italy.
Graphs of the efciency curves of all the models of inverter described in
this manual are shown below.
The efciency curves are linked to technical parameters that are continually being
developed and improved and should therefore be considered approximate.
