Right Angle Bending 1/0 Wire?

I get that however my configuration is due the necessity of how the inverter will be used. There will be no way to place the fuse any closer to the actual battery array I'll be tapping into.

Naturally I'll have to be far more careful to avoid placing the jumper cable-like clamps during use. For the most part that won't be a problem as most big truck batteries are very much out in the open air.

You can certainly put a fuse close to the clamp.

Ultimately you will have to decide on the risks and whether there is a hazard with these unprotected jumper cables. I have never seen a set of jumper cables with an inline fuse, but generally, jumper cables are only in service for a brief period.

The fuse on the board is a triple-redundant safeguard for the inverter as the inverter probably has built-in ANL fuses in addition to its normal function. This added fuse is protecting the wire from the fuse to the input of the inverter (from a short) but if that needs protecting then it begs the question about the rest of the cable which is probably much more exposed.

Indirectly I'm questioning the necessity of that onboard fuse and not having one at the clamp? You either put one at the clamp or none at all. The invertor already has one.

I know your configuration "looks" safer with an external fuse, but is it really?

If this was a permanent install, you would go from battery to busbar through a fuse leading out to an invertor. All this would be in close proximity and protected. The jumper cables are giving you a lot of exposed and vulnerable cable which is unprotected.

Perhaps some corrugated split tubing around the cables would be more effective if you don't want to fuse the cable at the clamp.
