[RE-wrenches] Outback GTFX errors

[William Miller]

Jon:

1. Outback inverters are notorious for reporting errors incorrectly.  Often 
the errors are a clue, but not the actual error. As an example, a shorted 
AC output might report a "Low Battery Voltage" error because when the 
output is shorted, the battery draw is momentarily very high, reducing it's 
voltage.  Look for a related symptom.

Have you been able to monitor the AC voltage during inverter sell 
operation?  High AC voltage in a grid-tie system can be caused by actual, 
intermittent high grid voltage and/or inadequate feeder size, allowing the 
inverter to push up the voltage at the inverter end of the feeder.  I've 
seen a bad breaker cause this as well.  In any of these described cases, 
the inverter error reporting would be accurate.

2. Outback sends out a standard kit of three field-replaceable boards.  You 
rarely need to replace all of the boards.  You need to figure out which 
board(s) to replace or, ask tech support.  I guess when in doubt, one could 
replace all three.  It appears you have narrowed the problem down to not 
one of the three boards.

Good luck.
