For more than two decades a market leader in the design and production of supply systems, Siel SpA has extended its range introducing “SOLEIL”, a line of inverters that convey photovoltaic energy to the power line.

Ranging from 10 to 500 kWp, the Soleil line is designed for installation in civil and industrial systems to be connected to the public power network.

“Soleil” units operate in fully automatic mode; once it has made sure that the voltage supplied by the cells is appropriate, the unit draws energy from the modules and starts the conversion process. After connecting to the network, the inverter begins to deliver energy to it.

To maximize the injected power, the MPPT (Maximum Power Point Tracker) control system continuously searches for the optimal operating point.

Soleil features a control panel that displays the inverter’s statuses and alarms. Displayed information includes, among other measurements, data regarding the photovoltaic field and the AC line section.

Thanks to different connection options and specific software programs, “Soleil” can be monitored remotely via PC.

Data are transmitted through fiber optic cables for higher immunity to disturbances and longer transmission distance.

Designed for use with photovoltaic fields with a wide range of output voltage, the inverters enable the use of a variety of photovoltaic modules.

“Soleil” is designed to comply with the following Italian and international standards: CEI 11-20, LVD, EMC, DK5950.
