Gday Bush,
I agree with Pete, I also had a change over switch on the house when we bought the place, it was grid and generator With hi and low power generator inputs 32A and 15A, we used the generator one quite abit when we had grid power that often blacked out, since removing the grid connection and cutting the power pole, the change over switch on some occasions gets used, I wanted to replace the main switch before the inverter, so just plugged the shed power into the gen input on the changeover switch, so no outage of any sort.
I'm sure there are many hybrid inverters that will switch back to grid with a low battery, most of the older design's used battery voltage parameters to trigger, will have to check which inverters use SOC to determine when to switch back to grid and charge....and you would likely need a battery with communication cable to the inverter, so lily a rack mount battery would do this, there should be some types of BMS that would also do this if building your on battery setup.
My other dislike is the ability for a lightning strike to come along the Grid connection and screw the whole thing up.........YES had it happen.
Edit:
It might be better to have a decent quality standalone inverter, away from the grid and a battery charger that is connected to grid and only triggered to charge the battery at your desired set point.
