[RE-wrenches] Outback inverter firmware mismatch

[William Miller]

Bill:

I am not sure how your point applies. This occurs on systems that have been running for some time.   I would hope equipment in this price range and this application does not need frequent rebooting.

After five visits to site (3 hours drive one way) Tech support eventually told me there had been a bad batch of comms boards on FXR’s but I had already swapped inverters out for VFX’s at last visit and issue ceased.  Definitely some sort of comms glitch causing the Mate3 to loose info on devices.
