Request for component choice 48v system

[Joshgabel]

I am in the process of building out a International box truck as a camper/toy hauler.

This is my first go-round with solar and was hoping someone could look over what i am thinking and tell me I've missed something or am completely stupid before my wallet tells me so.

The plan is to run the typical 12v stuff (basic lights, h2o pump, and a fan)
The non typical is a Mini-split AC/Heat pump system.

There are two flavors i have found for mini-split systems are as follows (spec sheet pictured in thread)

One is a 48vdc unit peaking at 980w and <500w normal
The other is 115vac 1050w

1. which would be more effeceint? Dc or Ac system.
2. Which would be more cost effective from a solar standpoint if i was to run it 16hrs a day year round (south texas)
3. Would the below gear handle such a task with 5hrs sunlight a day?

Solar parts im preparing to order unless someone tells me otherwise

4 -370w residential panels (santansolar)
1 -60a mmpt controller
16 - 280ah lifePo4 alibaba cells (build 4 12v batteries)

Possibly no inverter if the 48vdc A/C is a winner in yalls opinion. Maybe just a small one for chsrging cameras/laptop.

Why are you going to build four 12v batteries instead of one 48v battery?

Toy hauler?
Want to run any power tools? Air compressor? Welder?
With that big a truck you could put in a massive inverter able to power anything you want.

1kW DC or AC is small enough people would usually recommend 12V.
For an air conditioner, 1kW is pretty small. I do have a window air conditioner less than half that size.
The truck parked in the sun may be quite a bit of heat load for an A/C to get rid of. Start by figuring out how many BTU you are going to need, possibly using insulation and shade (e.g. awnings) to reduce it.
