Maximum energy and versatility for utility-scale projects


Better LCoE

Compact design which allows 2-inverter solution of up to 7.800 kVA in a standard 40ft skid, achieving  overall cost reduction by using less PV station units per project.

Design with best-in-class components that guarentees less probability of failure and therefore less operation cost (materials and workforce).

Market leading inverter efficiency of 99.52%.



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

Tier I supliers 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).


Grid compliance

An extensive list of grid-codes compliance, including the most demanding ones, such as Germany, Mexico, Jordan, South Africa and more.

Full operating range reactive power supply for both day and night operation through the so-called Statcom mode.

Non-characteristic harmonics cancellation over distorted and unbalanced grids (weak grids).


Higher yield

High DC/AC ratio (up to 200%) 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 even in challenging sites: operating up to 55ºC (up to 3.6% more energy production) and 2000 m (6561 ft) without derating.

Different product configurations available to fit any customers' needs
