Production Processes

Established in 1942, FIMER is a Company unique in the world.

Indeed, we have a completely new integrated systems of internal Logistic and Operations. FIMER integrates all the steps of the Supply Chain & Plant Construction.

Starting from design to production of semi-finished products, such as electronic boards, cables, metal works, up to the production of finished products, such as Inverters, Parallel boxes and combiner box, and to the realization of the complete Conversion Units, such as Welding Machines and Electric Vehicle Charging Stations. All over the world there are no other industrial Companies able to do that. Able to integrate in the best way every activity with the purpose of better controlling the whole production process and, above all, assuring the maximum flexibility and Quality standards to the Customer. In Europe, FIMER has the only Laboratory for Tests able to simulate any condition of the Connection grid at a global level. Thanks to this plus we can always be ready to reply to any connection rule of the market and be Compliant before the competition.

carpentry productionCARPENTRY PRODUCTION

Our internal carpentry department is fully robotized.

Thanks to this investment we can boast the most complex and advanced system currently present in Italy.

Each operation is computed, the punching, the stock sheet, the bending cells work in an autonomous way without operator, organised in three shifts.

automatic warehouseAUTOMATIC WAREHOUSE

Fimer Group has adopted a fully automatic and robotized internal logistics service. The main warehouse, with a capacity of 3860 pallet places, works automatically and in an independent way without operators’ intervention, as well as a secondary boxes storage for small parts. Even in this case, 4800 boxes are handled in a completely automated manner. Thanks to forklift trucks, unmanned and satellite-guided, goods move among various production floors independently. By scheduling orders daily, the system moves to feed steadily the assembly lines by continually providing the finished products to the warehouse.

Even in this department, FIMER is an absolute excellence. The Panasonic lines are able to mount up to 85,000 components/hour with absolute precision. All the welding process was assured by wave soldering to 3 preheating bodies to ensure a top-level lift tin QUALITY. Each FIMER card, to maintain maximum durability and reliability over time, after assembly operations is subjected to a rigid process of “conformal coating” where each piece is covered by a special protective resin.

This process is controlled by a completely robotized system.

renewable energy assemblyRENEWABLE ENERGIES ASSEMBLY

In addition to all the processes that make us 100% self-employed in the production, Fimer assemblies the finished product and its accessories as well. By string inverters, modular central inverters up to the entire 7.8 MW Conversion unit, everything is assembled and manufactured inside our facilities. This guarantees control of the processes and the highest quality finished product. A guarantee that characterized our Solutions for all their cycle of life. Today we have a production capacity, certified, of 4,12 GW/YEAR.

FIMER has been one of the first worldwide company to apply in 1983 such a technology in the field of welding. Thanks to our experience, we are now manufacturing 80.000 Welding Machines per year guaranteeing maximum inverter Technology reliability and performances even in the most severe use.


Fimer is the sole Company which has internalized the Conversion Unit production in its production System.

We are indeed the only ones in the global market who fully manage a complete Conversion Unit, and System Integration Projects from raw container to the finished product. This peculiarity has allowed us to gain a leadership position in the equipment utility market providing competence to the entire system, production flexibility and especially the ability to adapt to customer’s specifications.

services qualitySERVICES – O&M and QUALITY

Within our R&D Departments in Vimercate (Italy) we develop every day new products, technologies & advanced Solutions. Thanks to the design FW, SW, HW and internal mechanics, every day, we improve the “core” of all our products. FIMER has an internal division of Service and O&M that guarantees with the most advanced traceability Systems the perfect support for our customer, this is the reference point to for all the clients. The whole process is controlled and monitored since the first demand. Timing is scanned in order to reduce the response time.


Starting from approval to dispatch handling is fully committed to a series of robots for validation, storage and transport reducing to ‘0’ a possible human error. Warehouse area is therefore composed of a loading and unloading area where 5 monorail shuttles carry the goods inside and outside the warehouse. Storage area is divided into two areas: pallet storage to store bulky material and boxes storage to store small material and small parts. Everything is completely managed and handled through 4 stacker cranes that store the material up to a 22 meter height. Instead in the production areas material is transported by laser guided carries without operator. During each process handling step products are severely checked in order to avoid any possible human error increasing the product’s quality and process efficiency.
