Gamesa Electric Technology
Gamesa Electric has the necessary know-how, experience and resources to offer cutting-edge inverter technology for large-scale grid-connected solar plants.
The 2400+ photovoltaic central inverters installed around the world are a fitting testament to their outstanding performance. Such optimum performance is only possible through absolute control of both the technology and the product.
The company began operating in the photovoltaic sector in 1993, when the first 450 kW central photovoltaic inverter was designed and manufactured. The same year, the company rose to the technological forefront through the launch of Europe’s first photovoltaic inverter using 100 kW-capacity IGBT technology, which still remains in operation today.
LCoE oriented processes
Gamesa Electric has a comprehensive, LCoE optimized, process for designing, manufacturing, operating and maintaining its central solar PV inverters.
The development and application of cutting-edge technologies are balanced against a solutions cost optimized to maximum robustness, reliability and performance of all models. Research, development and innovation intertwined to form an essential DNA of all the processes and products offered by the company. This is continued throughout a product’s value chain as the company strives to achieve higher satisfaction for its customers.
The company product solutions are serviced by an extensive worldwide aftersales service network of employees and partners who understand the advanced control systems and product architecture, minimizing downtime.

Renewable energy market trends
Markets demand new products with reduced time-to-market goals
Products are required to accomplish with latest grid codes that increase the product performance
Prototype validation before field testing becomes critical to reduce commissioning time and project risks
New product size (several MWs) demands high capacity test benches that are hardly accessible
Product customization and component supply development demand test benches with full power capacity.
Electrical drive test benches demand enhanced capabilities such as LVRT (Low Voltage Ride Through), HVRT (High Voltage Ride Through) and Weak Grids
