TripleLynx
TripleLynx sets new
standard for string inverters
 Wide operation specifications
Voc: 1000v max., 250-800v MPP
range. 3x12 A DC current
 Max efficiency: 98%
 High MPP tracker efficiency
99,9% at static and 99,4% at
dynamic irradiation
 Three DC string input –
strings working independently
With TripleLynx, string
inverters have become an
attractive alternative to
central inverters for large
applications
