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.

I have a customer with an Outback GTFX 3048 that has an"over voltage
AC in" warning but when I check the voltage with my Fluke meter it
shows a normal range 122 - 126 V . In the Mate grid menu the AC high
Volts is set at 140 V . The customer called Outback support before I
could get to him and they told him he needed to have me change all 3
boards out. They sent the boards so I went ahead and changed them
out, but the same error occurred again. We called Outback support
again but did not get a satisfactory answer on how to fix it.
Has anyone else run into this problem ? I suspect the Mate may be flaky.
