Inverter + Bluetti ac200max, how to connect?

I want to add an inverter and a Bluetti solar generator to my Prius. What would be the most efficient way to connect these so that the Bluetti generator is charged by the Prius system in the best way possible? (I plan on having all electronics plugged into the Bluetti, not the inverter.) Would it be to connect the Bluetti to the inverter? So in that way, the Bluetti battery is used first, then the Prius battery system, then the engine kicking on to recharge in the opposite order?
Or, no inverter at all and just plug the car charger from the Bluetti to the 12v plug of the Prius? Would that be a much less efficient/slower way of recharging the Bluetti?
I’m thinking the inverter route is the better option as it also gives a backup plan if the Bluetti ever fails.
I want to utilize the Bluetti in my Prius camping set up (long term car living actually) so that I have even more capacity and the ability to take the Bluetti anywhere I please away from the car itself.
As for solar panels, my idea is using those only as a supplement to the Prius hybrid system. Perhaps just one 100w on the roof and a 400w suitcase set eventually. But even with that, my desire is to utilize the hybrid Toyota system as foundational for charging and obtaining electricity.
As for electronics I plan on using often: 12v fridge, kettle, induction stovetop, 250w heater, electric blanket, charging phone/power bank/laptop/headphones/etc.
Thanks for any help, ideas, comments and suggestions

 

I would be connecting a 1500w pure sine wave inverter to the 12v battery of the Prius. Then connecting the Bluetti to the inverter. Is this the most efficient set up to charge the Bluetti. Has anyone done this kind of thing before? The main reason I want to do this is to add capacity to the system. So that the engine has to turn on less when the car is stationary or off completely to run the fridge while I’m away from the car for 12-24 hours. I drive a lot so hopefully that will charge the Bluetti a good deal. And also, to have the portability of the Bluetti.

 

I see what you mean. In your opinion, would it be more efficient to just plug the Bluetti into the 12v factory outlet and that’s it? What would you do yourself for this situation? My mind still wonders, however, isn’t the factory 12v outlet a much slower charge for the Bluetti than an inverter set up? Thanks for your help

 

Really, my only goal is to charge the Bluetti AC200MAX generator. The Bluetti can be charged through the Prius factory 12v outlet. The Bluetti is designed to and comes with a cable to do so. So no worries about that. It’s possible and safe and so on. My question is, would it not be a much faster charge of the Bluetti to plug it into an inverter that is connected to the Prius 12v battery? I’m not an expert on this and have no experience with such a set up. So, factory Prius 12v outlet vs. inverter set up to charge Bluetti generator, which is better?

 

Thank you for your insight. It seems so obvious now. I looked up the specs on the Bluetti site. Charging through the 12v would be 100w and 10-20 of charging for a full charge. With the inverter it would be 500w and 5.5-6 hours of charging for a full charge. There’s even an option of dual ac charging at 800w and 3-3.5 hours for a full charge. This is the route I’m going to do for sure. As it also is a back up plan if the Bluetti ever fails.
I mean, I already knew that the inverter would be a way faster method of charging. I just wanted to hear if anyone has ever done this kind of thing before. Many have gone the inverter route and even a second 12v battery. But I’m yet to find a thread where a large capacity generator like the Bluetti has been added. The Bluetti ac200max has a little over 2000Wh of capacity and can be expanded further. With a 2200w inverter built in. Plus I will add some solar panels to add to the charging. All that must make it far superior than a second 12v battery, right?
Also, a big question I have is:
While remaining in ready mode. If I have the Bluetti connected to an inverter that is connected to the 12v factory Prius battery; will the Bluetti discharge first, then the 12v Prius battery, then the hybrid battery pack and then the engine would kick on? You see, I am trying to expand the capacity of using the factory Prius batteries so that the engine turns on less often. Am I on the right track of thinking here with this idea? I’m new to this form of electronics and need some advice from those with more experience. Thanks again

 

Thank you all for your insight. Very helpful. If anyone has any other tips or ideas it would be much appreciated.

I would never draw more than 800w through the inverter connected to the 12v factory Prius battery. The only thing I ever plan on using it for is 2 ac connections to the Bluetti generator for charging it. That is the only thing I would be using the inverter for.
Otherwise, all my electronics and electricity needs will be utilized from the Bluetti itself with its own 2000Wh capacity and 2200w inverter. The other stand alone inverter connected to the Prius 12v battery will only be used for charging the Bluetti generator. I just want to be clear on that. That is the heart of my design and I would like the opinions of those more experienced than me on it.
