I’m not super up on the Bluetti offerings and how they work, but here is a link to a post we made here about our solar setup.
its super similar to what’s mentioned above, three 100w flexible panels, a 1500x, and we are running a CFX 35, even with running Starlink, lights, charging cameras, drones, computers and so much more (we live full time in our truck) we never have an issue with power.
The only thing that we have changed really since we made that is that we have added the YetiLink Vehicle Integration Kit which allows us to charge the 1500x quickly from the alternator; however, it doesn’t allow simultaneous charging from the alternator and the panels, it picks what ever is delivering the most power input.
