Central Inverters

R7500 TL

With a 270 VAC output voltage and an MPPT voltage range of 485 - 820 VDC, the FIMER R7500 TL centralized inverter with MV connection to the electricity grid is a modular inverter which is ideal for commercial and industrial applications and suitable for all types of revamping projects.
MV central inverter

The FIMER solar product line supports a wide range of grid connected PV applications, from hundreds of kilowatts up to multi megawatts. Based on the FIMER MPS (Modular Power System) technology, this line has been designed with a particular architecture in which the power modules guarantee a greater efficiency than traditional central inverters. The power modules of our inverters switch on gradually, producing energy at low power values (around 700W), providing a rapid return on investment.

Thanks to such technology, FIMER inverters allow the improvement of the three main features of a PV inverter:

Improved performance

This FIMER inverter is modular and this particular feature is due to the inverter’s conversion stage which is formed by more IGBT power modules working in parallel in output on the AC power distribution grid. Taking a FIMER inverter that has to be connected to 750 kWp PV generator as a reference, this machine would be made up of ten 69 kVA modules.

Such modularity is also extended to magnetic devices (inductors), capacitors energy conversion and all cards and electronic devices for control and regulation (of which one piece is always embedded in each power module).

Longer service life

A FIMER inverter provides a longer and more reliable service life! Electronic components need to work at low temperatures to last longer. FIMER inverter power modules turn on and off in a sequential manner in order to always keep them cool (or they operate at low temperatures and are constantly monitored).

Moreover, in this manner the use of cooling fans is also optimized: they absorb and dissipate a reduced amount of energy by progressively turning less, hence ensuring a higher performance and profitability to the PV inverter.

Elimination of machine downtime

The particular power architecture of FIMER inverters ensure that they never stop operating completely because only the failing module inside the converter will stop, while the machine will keep functioning thanks to its multiple modules and multiple magnetic components.
