The Fronius IG 2500-LV is a compact grid-tie inverter with time-proven Fronius technology that gets the most out of all PV module types. Engineered to be smaller and lighter weight that other inverters in its class, the IG-2500-LV provides 208-volt, 3-phase power and is perfect for smaller commercial PV systems (under 2.5kW).

Fronius IG 2500-LV Inverter Features

  • Fully programmable operation
  • LCD display tracks more than 20 system performance parameters
  • 208V, 3-phase output
  • Operates reliably at full power without de-rating over a wide range of temperatures
  • Unique phase-shift technology maximizes switching efficiency and minimizes losses from switching
  • High-frequency transformer provides galvanic isolation
  • Integrated DC and AC disconnects (DC breaker is pre-wired to a heavy-duty terminal block that accepts up to eight #8 AWG conductors)
  • Convenient installer-accessible wiring compartment
  • WiFi interface
  • Module Manager™ software tracks and locks onto the array's maximum power point to optimize the energy output of the array
