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.<br><br>
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.<br><br>
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.<br><br>
Good luck.<br><br>

out, but the same error occurred again. We called Outback support

again but did not get a satisfactory answer on how to fix it.<br><br>
Has anyone else run into this problem ? I suspect the Mate may be
