If I want to plug my shore power cable into my inverter I need to switch of the converter correct? Where might I find it in my 2000 Airstream Land Yacht?

Look for a circuit breaker marked CONV or CONVERTER and see what all it shuts off. You may notice the lights dim a bit when you shut it off.
Also shut off the Refrigerator or lock it on GAS and turn off the water heater

This.

I would go a step further and turn off all the breakers and then only turn on the breaker for the item you are using. Otherwise, you may be powering items you don't care about burning thru battery power for no benefit.

Motor home or Trailer? What Brand and Model Inverter? What size Inverter? Is it a Inverter/Charger or just an Inverter? WHAT Battery bank are you using to power the Inverter? What are you attempting to power with the Inverter? Doug

YES.
Look in or near the cabinet with the 120v breakers or the stack of 12v fuses.

Indeed, for the sake of your electrical system, if you do decide to plug your shore power cord into the inverter OUT, turn off all the breakers that you do not want to power from your inverter.

It would be easy for someone to forget and turn on your roof A/C. NOT a good idea!

Much, much safer to either wire the inverter OUT to a sub-panel or directly from inverter OUT to just those outlets you want powered by the inverter.

Since an inverter changes 12 volt battery power into 120 volt, why would you plug 120 volt shore power into an inverter?

I don’t understand the point of this. Is it to not have to wire the inverter into the AC breaker box?
Because surely you’re not plugging a live shore power cord into something that effectively generates “shore power.”
Going to need to explain better, for me at least, what it is you’re trying to accomplish.

Thanks for the replies. Yes I found the breaker for the converter. I'd only be using it for a coffee machine. My TVs etc are all 12v. I got the inverter mainly to charge the eBikes we just bought.

If you are considering only two "outlets" able to be powered by the inverter, consider just wiring the inverter OUTPUT to two outlets.

What is amp draw to charge your eBikes?

What size battery bank do you have?

Wonder if generator run time to recharge the batteries will be any less than generator run time to charge the eBikes directly-- neither charging nor inverting process are 100% efficient, so you are loosing efficiency at both ends.
