[RE-wrenches] Midnite AIO Random Unexplained Shutdowns

[Maverick Brown]

I have the same issue, but a single inverter installation. It happened a few times at night. 

No log entry. 

Tech support suggested upgrading to version 7. I asked for release notes. I haven’t upgraded yet, I haven’t had time to go babysit it for the customer. I’ve been trying to train the customer to do it himself. (bypass mode, standby, etc. I did install a bypass switch and I also installed a bluetti battery on the router.) 

Release notes would be nice. 

Thank you,

Maverick

The inverters will simply shut off, going into standby with no power to the loads, and absolutely nothing in the fault logs. Turning them back on with the master inverter power switch or remotely with app restores normal operation for some random period of time before it happens again.
