Gamesa Electric has signed an agreement with Elecnor Atersa to supply its Proteus 4300 inverters for the Portón del Sol solar project being developed by Enerfin in the Colombian department of Caldas.
The agreement involves delivery of 28 inverters, integrated in 13 PV Stations of 8.3MVA and 2 PV Stations of 4.15 MVA, with a total power of 116.2 MVA. It is Gamesa’s largest project to date in Colombia.
In addition to having to comply with the Colombian grid code, the equipment was also required to have RETIE certification, the mandatory technical regulation for electrical installations in Colombia. The inverters feature seismic reinforcement, CH4 corrosion protection and a design temperature of 45ºC in order to adapt to the demanding conditions of the location.
“We are delighted to collaborate with Elecnor on one of its photovoltaic projects in Colombia,” commented Enrique de la Cruz, Sales Director for Solar & Storage at Gamesa Electric. “This project is another example of how competitive the Proteus PV inverter is for large-scale projects. This is mainly due to its high-power output, which requires less equipment. Moreover, its record efficiency level and low harmonics allow a plant’s production to be optimized”.
The Proteus inverter is one of the most powerful on the market at 4700 kVA and offers a record efficiency of 99.45%, with an extremely low harmonic level (THDi) of 0.7%.
The high rated power, outstanding electrical efficiency and low harmonic values lead to significant improvements in LCoE by reducing the number of inverter units per project, thus saving on logistics, construction, cabling, commissioning and maintenance costs. In addition, the higher efficiency values and lower losses result in higher energy production at the solar plant level, contributing to a further reduction in a project’s LCoE.
