Photovoltaik -Inverter
Quality power distribution
The range of inverters for Sirio photovoltaic plants uses high
quality innovative technologies and components, having a large
margin compared with normal operating conditions, and reaching a
high level of reliability (Mean Time Between Failure > 100.000
hours). These technologies and components mean that the periodic
maintenance of the equipment can be avoided without compromising the
operating flexibility of any photovoltaic system and any electrical
grid. Sirio inverters integrate protection against input and output
overvoltage and are equipped with redundant control and protection
devices, especially in the output phase (double relay with double
control microprocessor), giving further guarantee of operability and
continuity of operation.
High conversion eficiency
In small photovoltaic plants reduction of energy loss during the
conversion process is essential. In the search for maximum
efficiency to reduce losses, inverters of the Sirio series up to
10kWp are made without transformers and moving parts. This
construction philosophy allows for the reduction in the footprint
and weight of the inverters and increases reliability over time by
eliminating the parts subjected to mechanical wear. Thanks to this
“transformerless” technology, Sirio photovoltaic inverters guarantee
a conversion efficiency up to 97% which is amongst the highest
levels in this category.
Easy installation and use
Light, compact and with an attractive design, the Sirio series
inverters are easy to use and simple to install. An LCD display on
the front panel provides a simple and intuitive display of all the
main data: power, energy produced and any failures. The display can
also show other parameters such as grid voltage, photovoltaic module
voltage and grid frequency.
Reduced noise
The Sirio series of photovoltaic inverters have been designed with
static electronic devices without the use of rotating components and
cooling ventilators, thus reducing noise considerably.
Simple communication
All models in the series have a standard RS232 serial connection
(RS485 optional) enabling all information accessible locally on the
display to be available from remote locations. The optional remote
device SOLAR VIEW allows the acquisition and display of the main
electrical parameters (voltage, frequency, current, instantaneous
power and total energy transferred on the network) besides
information on operation and on any
inverter alarms (up to 5 units).
