[RE-wrenches] Midnite AIO Random Unexplained Shutdowns

[Tyrone Houck]

I recommend doing the v7 update and following the installation tips pdf.
With parallel inverters do the update onsite and clear the data/5 minute
shutdown per  recommendation.  With single inverters it works fine remotely
if you can keep internet on(I've just had the customer put it in bypass
until the update was finished). V7 also includes an arc fault firmware
update. V7 firmware has appeared to fixed this issue at the sites I've had
issues with. I have yet to have an unexplained shutdown at any of my sites
on v7. Hope that helps. It sure has helped me sleep better at night!
