Hi, We have an SB 6000 US Sunny Boy inverter manufactured and purchased in 2008 that recently died. It is giving the "Disturbance, fac-bfr" error for line frequency. Line frequency is fine and powering down/power it back up does not clear the error, so I called SMA and they said they do not repair inverters that are out of warranty. I am looking at replacing it with either a new SMA or a SolarEdge inverter. I have two questions:
1) Is 11 years service within the normal range for an inverter?
2) Which brand inverter do you recommend?
