Have not heard of bluetti but it looks like a nice power station.
I have a goal zero 1250 in my van chained to two 125 amp agm batteries. All my lights, fans, water pump, stove ignition are wired to the house batteries. I use the goal zero for my 12v fridge, phone charging, and solar input. It works well for my needs.
I would of liked to go lithium but I didn't want to pay for it lol
