I second uprading all firmware on all devices. I had a recent FXR
install that was dropping one of the inverters (and its leg)
whenever the system tried to sell. Latest firmware cured the
issues. <br>
The industry is moving from us being electricians to becoming
computer techs. Retirement looks better each day.<br>

<p>Very strange that all the programming is scrambled. <br>

<p>Recently we had a FXR system which had been working fine for
nearly six months come up with an incompatibility error with
the slave inverter even though the firmware was the most
recent and the same for both inverters. After several failed
attempts to re-upgrade the inverter firmware, we took a shot
at upgrading the Mate 3 firmware which did work. We then again
tried the inverters and it worked. System is now working again
(for now) and the programming is all still valid.</p>

<div>I maintain an off-grid, 8 stack FX Outback
system with 3 charge controllers. The system has
been on line for about 6 years. It got upgraded
about 7 months ago with 2 Mate3s.</div>
<div><br>
</div>
<div>About a week ago the system shutdown, leaving
the customer without power. A maintenance worker
started a generator and power was restored. I did
not hear about the situation for several days.</div>
<div><br>
</div>
<div>A maintenance supervisor was dispatched
yesterday to work with me over the telephone to
see if we could restart the system. The system
would only run if the inverter output breakers
were all off. </div>
<div><br>
</div>
<div>I examined the system via Optics. I was very
surprised to see that the system programming was
absolutely scrambled. This was so much so that
even the stacking settings were wrong. For
example, inverter 2 was set as a Master, which we
all know will crash any system. Other settings
were also found with very random values.</div>
<div><br>
</div>
<div>This system was running prior to last Friday,
so the stacking at least must have been right
prior to the outage. I am completely mystified as
to how this could have happened. </div>
<div><br>
</div>
<div>I am in conversation with Outback who is taking
this seriously. I have not heard back from them
yet but I am curious if anyone else has
experienced this or anything similar. I'd like to
broaden my knowledge on this situation to enhance
my understanding and to share any findings with
the group.</div>
<div><br>
</div>
<div>Thank you in advance for any input.</div>
