Roof Auxiliary Power Tap / Power Feed Specs (48V)

[Petertsai]

Still doesn't stop the bending from fatiguing and possibly breaking the wires.

Also looks a bit thin for 2.3kW at 48V, so 47A. Is there another one maybe?

2.3 kw LED lights would be incredibly bright and powerful. I don’t think the light power bar would be that powerful.

They claim 400 watts for the frunk in the latest T-Sportsline video.

T Sportline: "Confirmed with Tesla, both [roof | frunk] auxiliary power taps are rated to 400 watts. Both are protected with solid state circuits, if you exceed 400w, they shut off."

(400 watts) / (48 volts) = 8.3 amperes

Yeah saw that on the other frunk thread.

Its highly likely they are both 400W as that would match the cable sizing as well.

If so I suspect they won't be bidirectional in any way, and are just simple 48V (10A?) relays. That would obviously also mean there won't be a solar connection using those feed lines.

might go for this and add two smaller side and a rear as well.

Do we have any more information on that constant 10-12v line (green)? Does this turn on/off with vehicle? Or is it a sort of, "you don't have a 12v battery so here's a line that acts like one"? Not clear on that still or what it's capable of.

Context:
Wiring a 12v relay and fuse box with a bank of interior switches for 12v accessories: Warn winch, arb compressor, ditch lights, etc. It appears the green line could power that without setting up my own step down.

? The video stated at 1:08 the details of it.
