I'm sorry, I have to chuckle in regards to this discussion.Cable must be 4 awg at that length
What seems to be lost here is comparing apples to apples.
As much as the Victron Orion XS can potentially output 50A, it does not have to; you can easily configure it to output a lesser current.
If charging from the alternator was the primary battery charging source, maybe then I would consider running the XS at its maximum output, but if it is just a supplemental charging source then I probably wouldn't.
Charging from the alternator, be that while you are driving to a location or when you are stationary, this would be a 100% reliable charging solution, unlike a wind turbine, that requires a decent velocity of wind, that is unlikely to be available 100% of the time.
Also... I'm pretty sure that the wind turbine you are looking at does not output anywhere near 50A, so making a direct comparison between this and an alternator charging alternative seems ludicrous to me.
As I said... apples VS apples
Working to a budget is not a bad thing, but in my opinion, scrimping on necessary items is not a good idea.
As I see it, a wind turbine is a nice concept, in theory, but being a practical solution in a mobile scenario seems a little questionable to me.
This wind turbine is quite large, probably not suited to a mobile installation and has a limited current output. Compare that to the XS, which is small, light weight and something that can reliably output up to 50A.
Sure, the XS may be a bit more expensive, but it also offers a lot more than a wind turbine.
A mistake that I see many people making on DIY builds is focusing on individual costs of items, opposed to looking at the overall cost of the project.
Saving a couple of hundred bucks on a specific item is inconsequential when looking at the overall project cost.
Things will cost what they cost. DIY builds will normally cost more than you have planned for; that's just a fact.
Accept that and your stresses will be less and after the build is completed you won't even remember what the small item costs were.
