There are hybrid (grid tie/stand alone combo) inverters you can buy which will either work in parallel with the grid or off grid. Those are nice because they are bidirectional and will either charge the battery or provide additional current if your day in a 15A circuit trying to run the a/c and micro. But theyre expensive and FR doesn't offer them.

The additional specs you provided are mostly for the inverter function and are pretty typical. None of that tells us what the voltage or frequency limits are that trigger the ATS to operate. That might be covered in the UL standard that the ats was presumably listed under. I'd guess the limits would be pretty loose if they existed, UL standards are safety not performance standards.

Of course, a total power failure would trigger it. My feeling is that if you feel you need brownout protection, hanging an EMS in front of the inverter/ATS would do it, because the EMS setpoints would determine when the ATS sees an outage. Short of that if you have a visibly low grid voltage situation you can just disconnect and manually trigger the transfer.

With the inverter/battery available, you only need an autotransformer if you don't have a generator and want to run the a/c or expect the low voltage condition to last a long time, the inverter/battery will take care of your low power appliances and short duration voltage drops.

Thanks offgrid,
I'm totally with you now.  If the grid power goes low, the EMS will kill the power to the pod, but life in the pod goes on (other than AC & Microwave) thanks to the Inverter's ATS.

And I've got all winter to look for an EMS Smile  ... Cry dang, winters coming...

If you have the same inverter I do, then if the EMS kills shore power you would have to switch the inverter on...I don't believe it's automatic.  The battery won't last too terribly long if you're powering more than the lights and low-amp 120-volt items.  Using the hair dryer and coffee maker will be an issue.

If you're worried about low-voltage scenarios I would look at the autoformer option, which as I mentioned above just came in very handy when we encountered a low-voltage situation for the first time.

We have a Renogy 1000watt inverter hooked to our twin 12volt LA batteries. It will handle a small 4 cup coffee maker and a couple of pieces of toast. I wired seperate outlets for the inverter (to keep things simple) and it all works fine.
