I think you said you’ve tried it open and closed loop same issue.
In the open loop are the batteries connected via comm cables between the batteries?
and do you know if they are connected together via comms does that mean they will all shut down if one shuts down?
And you’re sure it’s not some weird load that is shutting the inverter off?

The DC Battery voltage goes to zero on the inverter for a moment, and then returns. The problem is, it requires manual intervention to push the button to turn the inverter back on. It does not happen automatically. That's not good for an unmanned remote site.
