The largest solar power inverter in the power-one Aurora product range, the new Ultra 1.4mW unit is designed with large utility-grade installations in mind.

This liquid-cooled, high-powered Aurora inverter is the largest pV inverter available in the market. The compact chassis gives maximum power for the minimum footprint.

industry-leading power conversion efficiencies of up to 98.7%, combined with high-speed maximum power point Tracking (mppT) channels, optimize energy harvesting across a wide array of operating conditions. Up to four independent mppT input channels offer maximum flexibility and energy harvesting.

This large inverter system significantly reduces the wiring requirements and on-site testing thanks to the presence of separated and dedicated compartments for Dc and Ac.

High performance utility grade inverter for large utility pV installations with 98.7% efficiencyoutdoor enclosure for unrestricted use under any environmental conditionspassive liquid cooling with total segregation of internal compartments assuring a 5-year maintenance cycleReduced susceptibility to a single fault. in case of a component failure, a maximum of 350kW will be lostextended mppT input voltage rangeDirect transformerless conversion to the 690 Vac output reduces Ac distribution costmaximum input voltage up to 1100 Vdc, high design flexibility and reduced Dc distribution losses for large scale pV plantsintegrated Dc and Ac distribution and protection. fully equipped for connection, additional accessories not requiredeasy installation and maintenance procedure. front extractible Dc/Ac converters and accessibility to all critical partsethernet communication and two independent RS-485 communication interfaces for inverter and intelligent string combiner monitoringcompliant to BDeW and feRc 661
