INTRODUCTION
This document describes the features of the Three-phase Solar Converters of the SIRIO series without
isolation transformer dedicated to medium voltage connection.
The SIRIO inverter is used to transfer the energy produced by a photovoltaic generator to the three-phase
power distribution system. The MPPT (Maximum Power Point Tracking) feature ensures that the power is
drawn from the photovoltaic modules with the operating point continuously optimized in relation to the
irradiation conditions, the characteristics of the panels, their temperature and the converter
characteristics.
The system is designed to allow it to feed into the network a current with a sinusoidal waveform and
uniform power factor in all operating conditions.
The operating parameters and electrical values can be displayed locally, by means of the alphanumeric
LCD display.
The functions listed above are obtained by means of power electronic architecture of the PWM (Pulse
Width Modulation) type using semiconductors of the IGBT (Insulated Gate Bipolar Transistor) type and a
microprocessor-based control logic which can carry out all the required processing in real time.
As example the figure below shows the K500 HV MT inverter block diagram:
•EMC filters: these are used to reduce conducted radiofrequency emissions on both the
photovoltaic modules and on the AC network
•Power Module: this is the section in which the energy from the photovoltaic modules is converted
from direct current into alternating current.
•AC filter: its function is to recreate a sinusoidal current waveform by eliminating the high
frequencies generated by the inverter stage.
•Contactor: separates the inverter from the AC network during periods of non-operation.
•DC disconnector: disconnects the photovoltaic field from the inverter to allow maintenance to be
carried out on the inverter. K330 and K500 models use an automatic DC disconnector with motor.
•AC disconnect switch: disconnects the inverter from the AC network in the event of maintenance
and is triggered to protect the network in the event of an internal fault in the AC section of the
device
•Control system: this is the heart of the entire system that manages all parts of the equipment.
•Communications: for local monitoring (LCD display with touch screen) of inverter operation or
remote monitoring by means of appropriate electrical connections.

STORAGE
If the inverter is not installed immediately, it should be stored with its original packaging and protected
from humidity and the elements. The storage premises should comply with the following characteristics:
Temperature: -25°C ÷ + 60°C (-13°F ÷ 140°F)
Relative humidity 5 - 95%
Recommended storage temperature is between +5°C and +40°C.
INSTALLATION ENVIRONMENT
The equipment has been designed for indoor installation. The choice of premises for installation should
comply with the points set out below:
avoid dusty environments;
ensure that the floor can support the weight of the inverter;
avoid narrow environments that could hinder normal maintenance operations;
avoid placing the device in areas exposed to direct sunlight or heat;
ensure that the ambient temperature, with inverter operating, is less than:
operating temperature: -20 ÷ +50°C
maximum temperature for 8 hours a day: + 45°C
average temperature for 24 hours: + 35°C
Relative humidity 5 -95%
N.B.: the operating temperature recommended for the lifetime of the inverter is between 10°C and 35°C.
A heat dissipation system is required to keep the temperature in the installation site within this field (the
value of the power dissipated by the inverter is shown in the section “GENERAL CHARACTERISTICS).
PRELIMINARY OPERATIONS
Checking the packaging
•Upon receipt of the inverter, check that the packaging has not been damaged during shipping.
•Check that neither of the two impact resistant devices on the packaging has turned red; if one of
them should be red, follow the instructions on the packaging.
•Care should be taken when removing the packaging in order to avoid scratching the inverter
cabinet.
•The device must be handled with care; it may be damaged if knocked or dropped.
•This technical user manual is supplied with the inverter.
The device should only be handled by appropriately trained personnel. It can be unloaded from the vehicle
and put into place by lifting the box or the wooden deck to which the equipment is secured with a fork-lift
truck. A trans pallet or fork-lift truck should be used for the permanent positioning of the equipment, in
accordance with the instructions provided below.
