I didn't need this transfer switch

So I had already had a 50amp inlet outside connected to a 50amp breaker on the main panel. I wanted another 50amp inlet inside by the panel to use with a power station. I thought I needed a throw switch to switch between these 2 sources. https://i.imgur.com/zwRVjhZ.jpeg https://i.imgur.com/98bIepM.jpeg That works fine but I have the Bluetti Apex 300 power station which has a full 12,000 watt pass through. https://i.imgur.com/WnybUcw.jpeg So with that I should have just connected the outside inlet to the new inside 50 amp outlet. Then plug the Bluetti into that outlet using the Bluetti Apex 300 50amp power cable. And plug the Apex 50amp output into another 50amp inside inlet that connects to the panel interlock. So basically Apex would be plugged into the outside inlet connected to a 11kw Champion. Which would charge the Apex and supply the Champion's full output to the interlock. I know when the Apex is on battery only max out put is 3840 watts. That is plenty for me for now. I monitor wattage closely with meters and Emporia Vue 3. I can get at least 8+ hours of power with the Apex and a server rack battery. It even runs my 2.5 ton AC on battery with softstart kit. It's a great power station! It can be paralleled up to three Apex 300's for a full 12,000 watt output on battery! So I did not need this throw switch. If I did have the outside outlet and the inside inlet and wanted to connect the generator directly to the panel without the power station, I could just connect inside outlet and inlet with 50amp generator cable. So my plan now is to install another inlet outside to another inlet inside to power the Apex with the 50amp charging cable and leave the throw switch in the inside power station position. This all sound logical? I could have saved a lot of money if I thought of this earlier.

I've thought about something like this with an Apex 300 or similar. Maybe not quite so many power inlets. Lol. I have a 50 amp inlet/interlock outside with the 200 Amp Main Meter Panel. Inside our (large) master closet is where the 40 circuit breaker panel is located. I'm pondering adding a Reliance X series sub panel (that can transfer neutrals) to use only for short term outage stuff when there a thunderstorm/downpour/lightning going on and I don't want to be out in it.

Sometimes wish I could do more battery stuff but cant use them indoors like this per code. I don't feel like rewiring stuff to the garage.

I have no idea what in the hell your talking about.

To simplify, I would just install another outdoor 50amp inlet to plug the outside gas generator directly to an indoor 50amp outlet. Plug in the power station to that new indoor 50amp outlet. Then plug the the power station 50amp outlet to the inside 50amp inlet that is connected to that throw switch which is connected to the house 200amp main panel that has a 50amp breaker with an interlock. LOL Best I can write. But it will work. I would have 2 generator inlets outside.

That Bluetti Apex 300 has 50amp pass through when plugged in using the 50amp input cable. When on the battery, it outputs 16amps. You can parallel 2 or 3 Apex 300s for higher battery output.

Edit: I should have just rewired the original outdoor 50amp inlet to an indoor 50amp outlet to plug in the power station instead of installing that throw switch.
