Fronius Argeno 125.0 – three-phase string inverter


The Fronius Argeno 125.0 is a highly efficient three-phase string inverter designed for large commercial and industrial rooftop and ground-mounted photovoltaic systems.

  • 10 MPPT (with 2 inputs each)
  • Arc fault protection (Fronius Arc Guard)
  • Integrated surge protection type 1+2
  • Communication via LAN, RS485
  • Up to 7 years base warranty (extendable)

Efficiency and flexibility

Thanks to silicon carbide technology, the Fronius Argeno 125.0 achieves a maximum efficiency of 99.1 %, with higher power density and more efficient thermal management, also made possible by the active cooling system.

The 10 independent MPPTs allow high design flexibility, ideal for installations with different orientations and inclinations. In addition, the high input current (up to 30 A per MPPT) makes it compatible with the latest generation of photovoltaic modules.

Safety

The system includes built-in type 1+2 overvoltage protection and the Fronius Arc Guard safety feature, which detects and interrupts arcs in time and thus increases the overall safety of the system.

On the software side, the inverter relies on servers and systems certified according to European safety standards, which guarantees the protection and proper management of collected data.
