SIEL is the Italian company which works internationally in two crucial fields of modern civilization: electric power safety and renewable energy production.
In its Italian headquarters of Trezzano Rosa, Milan, for almost thirty years SIEL has been producing emergency supplying systems for public and private customers, providing with “save energy” several highly critical sectors such as infrastructures, finance, telecommunications, health service, mass retail and data centers.
SIEL’s production is certified ISO 9001 and can boast innovative projects and technologies along with top quality components. Its wide product range includes highly performant UPS systems: its various sizes and types dedicated to large and small users can guarantee high performance levels, total reliability, low running costs and a fast maintenance.
In the field of renewable energies, since 2000 SIEL has been dealing with PV and wind powers through its product lines SIAC Soleil and SIAC Wind Wave. Nowadays, SIEL is one of the main world producers of PV and wind inverters and of high-power three-phase inverters. Its range of solar and wind inverters – suitable for stand-alone, grid-connected and hybrid applications – can match every request in terms of power and usage, being supported by a set of services which includes telemanagements, multiannual maintenance, specialized consulting and free-call help-desk.
SIEL has been co-operating with several renown energy suppliers in many successful international installations. SIEL’s commitment in promoting and sustaining new energy involves the whole Company’s life and activity, from production to after-sale services, through the adoption of governance and social responsibility criteria.
