Inverter question.. How many/big do I need?

[DHudson]

I know nothing about inverters beside they convert 12v to 110.
My 2000 Dutch Star DP does not have a inverter. I would like to add 1?, 2? I think.
It has 2 Brisk 15,000 ac units, 2 TV's, Coffee pot, 2 Computers, 2 phone chargers.
Gas stove top, gas furnace, gas, 12v refrigerator.
I know that we will not be running everything at once. But may need both AC's at the same time and have a tv and computer going.

It has a 7500 watt generator, but just wondering how long I cold run mostly ac's on battery power. And would I need 1 inverter for each AC,
and maybe another on for other stuff?

How many converters would I need (2 6000 watt?) and how long would my 4 - 6 volt golf cart batteries last with out a charge.
How long would the batteries last if I ran 1 ac will driving?

Any input would be appreciated.

Thank you in advance,
Danny

Danny, I just looked at the brochure for your coach and saw that Newmar offered a 400W inverter as an option to run the TVs. In case you haven’t seen it, here is a link to the brochure. https://newmar.imgix.net/wp-content/uploads/2019/02/27073547/2000-dutch-star-class-a-diesel.pdf

Your coach, and nearly all others, do not have the battery capacity to run ACs off of an inverter. I have read of some folks who have installed robust lithium battery banks and been able to do it for short periods, but those are rare instances as far as I know.

If you want to run ACs while on the road, you’ll have to fire up your generator to supply the proper amount of 110v AC.

Yes, I have the brochure. Saw that about the TVs.
Didn't know if running the AC off batteries would be a thing or not. Didn't really think so because of the draw they would pull. But never know until you ask. Thanks for the reply.
