I have one of the Fronius 5.0 models but not sure which one. The Fronius has served me well although it has malfunctioned several times over the 8+ years that I have had it. However, each time that it malfunctioned, SunStar Energy repaired or replaced it completely free of charge and under warranty. This inverter was installed in 2005 along with 27 Sanyo PV panels generating 3.9kwh. In 2012, I added 9 Trina panels, increasing total max. production to 5.1kwh.
