When I am on my way home, if I stay at a place without electricity, will my inverter run down my batteries too low ?

Yep. You'll need to run your generator or have a lot of solar output.

It depends upon how much power the inverter uses, battery charge and capacity.

For every 120V amp for inverter output it will draw 11 times that many amps from the battery.

Adequate batteries and solar charging would make you independent of an electric hookup. Run the numbers...battery amp hours, fridge and other draws...see what you are using.

Since there are several variables involved in determining how long an inverter can power an AC load, without pertinent info it's likely you will need to replenish your battery bank if staying more than a day, sooner if you only have a couple of batteries. We do most of our RVing off the power grid utilizing solar and occasionally our genny/Iota IQ4 smart converter to quickly restore consumed amphours to our 12 volt reserves.

All inverters will shutdown if the voltage get too low. The question is "What is too low ?" and "Will that damage your batteries ?"

Not enough information ! Make and model of inverter. Make, model, quantity of batteries.

Maybe, maybe not. Two well charged batteries and pre-cooled fridge should make a 12 hour stop with minimal time with the door open. Bad time to chill a case of warm beer. Otherwise the battery will be a bit low in the morning but will begin charging from the alternator as soon as you roll. Battery may arrive home a bit low as charging will be slow to none as the inverter will use most of the power from the truck. So plug in and charge 5+ hours when you get home. Two nights in a row could be more of a challenge with no generator.

How far is home? We have driven 3 days with overnight stopping in between and our fridge was still cold when we arrived. I guess it will depend on how topped off the batteries when you leave, outdoor temp, how many batteries you have and lots of other variables. I will say that our batteries died on one trip, but the fridge and freezer still held their cold.
