LCoE down


Better LCoE

With 3420 kVA, one of the largest central inverters in the market, achieving overall cost reduction by using less units per project.

Design with best-in-class component guarantees less probability of failure and therefore less operational cost (materials and workforce).

Market leading inverter efficiency of 99%.



Smart liquid/air cooling system that allows critical components to work at temperature level far below the limit, guaranteeing product lifespan.

Tier I suppliers for critical components (power semiconductors, capacitors, inductances and control cards) with best-in-class MTBF values.

“Easy to support” concept, with heavy components in removable trays, reducing maintenance and repair time (MTTR) installed worldwide in both solar and wind.



High DC/AC ratio (up to 2) to be prepared for bifacial modules, achieving higher production values.

Enhanced MPPT algorithm that provides outstanding MPPT efficiency values at static and dynamic states.

More yield in challenging sites: operating up to 122ºF and 6561 ft without derating.

  • Two full power test benches available with 3.5 MW and 5 MW capacity
  • Upgrade to 6 MW by end of 2019
  • Each test bench has:
    • High speed drives made in house (motors and drives)
    • Virtual grid to perform 50/60Hz, PQV curve characterization, HVRT/LVRT and weak grid tests
    • Water-cooled systems and close-loop transformers to minimize grid losses consumption
  • Outdoor design IP54 & NEMA 3R C4H
  • Up to 60ºC operating
  • Water + Air Cooling System
  • Better for dusty environment
  • Selective Cooling
  • Continuous Temp. monitoring
  • H <= 2000 m
  • Tier I suppliers for main components
  • Field-Proven Components: CCU
  • Control Unit (CCU) MTBF: 40 years (over a 2.000 units population*)

    * Currently there are more than 6500 units in operation (G5x, G10x and PV Inverters). Study has been carried out on 2.000 units and more than 40 million operating hours.

  • Easy Access to main components
  • Easy to Maintain
  • MTTR
  • Reactive power generation with constant power factor in the inverter
  • Variable reactive power according external control/commands:
    • To maintain PCC voltage
    • To maintain PCC power factor
    • Night reactive generation
    • To compensate power factor of an installation connected to common PCC
  • Gamesa Electric Inverter is able to generate reactive power at night up to nominal power with an active power consumption < 2% of the generated reactive power
