The project will be implemented throughout 2025 and includes the replacement of the existing inverters with 59 next-generation FIMER units. All plants are equipped with single-axis trackers to maximize efficiency. Furthermore, a sequential regeneration approach has been applied to oil transformers to extend their lifespan and enable sustainable reuse of existing components.
To date, four out of the seven plants have already been reconnected to the grid, with full completion expected by the end of the year.
"Puglia is a strategic region where we have operated for many years with great commitment. It continues to lead the way in the development of the photovoltaic sector in Italy. Our goal is to make our plants increasingly more efficient and high performing, strengthening our leadership in the sector and working alongside highly qualified partners in Italy and Europe", said Gian Luca Teodori, Head of Operations at EF Solare Italia.
Giovanni Manchia, Chief Technology Officer at FIMER, added, "We are pleased with this project. Together with EF Solare Italia we once again demonstrate that revamping is not just a technical upgrade but a strategic opportunity to enhance the value of solar assets and ensure long-term investment sustainability.
"With our PVS-100-TL string inverters—a cutting-edge technology in terms of efficiency, reliability, and flexibility—we guarantee long-lasting performance and accelerate the energy transition in Italy.”
This project highlights the shared commitment of EF Solare Italia and FIMER to advancing sustainable, high-performance solar energy. It is a concrete example of the joint strategy between the two companies to enhance local communities, optimize renewable energy production, and contribute to Italian national decarbonization goals.
Inverter data sheet:
The PVS-100/120-TL is FIMER's cloud-connected, three-phase string solution designed for cost efficient decentralized photovoltaic systems for both ground mounted and large commercial applications.
This platform, for extreme high power string inverters with power ratings up to 120 kW, maximizes the ROI in large-scale applications. With up to six MPPT, energy harvesting is optimized even in shading situations.
The high-power module saves installation resources and costs as few units are required. Its compact size also generates additional savings in logistics and in maintenance. Thanks to the integrated DC/AC wiring box — featuring 24 string connections, surge protection, and fuses — no additional boxes are required.
Standard wireless access from any mobile device makes the configuration of inverter and plant easier and faster. The mobile APP for installers, available for Android/iOS devices, further simplifies multi-inverter installations.
