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.
The industry is moving from us being electricians to becoming computer
techs. Retirement looks better each day.

Very strange that all the programming is scrambled.
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.

I have no reason to believe anyone has been meddling. No one knows the
password. It does look like some serious glitch.

Colleagues:
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.
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.
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.
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.
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.
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.
Thank you in advance for any input.
William Miller
