EG4 Split Phase 6K off grid inverter ATS questions

My inputs would be the grid and PV, my output would be AC to loads. I'd have a solar array and EG4 batteries.

When the grid goes down does the AIO keep putting out power as long as the batteries are above the minimum?

When the grid goes down and comes back up is there any kind of a manual reset required?

When the grid goes down and solar is below the battery minimums: When either solar catches back up or the grid comes up is there any kind of a manual reset required?

Thank you!

I have 4 3000w growatts in parallel make 12000 watts at 240 volts.
They are grid tied only for pulling power from the grid for winter.
They can be set to behave in a number of different ways.
I have mine set to sbu meaning Solar, Battery, then Grid.
Mine switches each day in the winter twice once around midnight to the grid and once
in the morning around 8 or 9 when there is enough sun.
The lights flicker once on the transfer and that is all.
If the grid fails it just switches back to battery.
If the batteries are too low then the inverters will shutdown if no grid.

a proper power up using precharge resistors is needed when the batteries completely turn off.
I use a product called solarassistant to control transfer to/from by battery state of charge.
It also logs everything power user, solar in , battery in/out grid in
