negativeThe busbars are like the risers.
The circuits are like the rungs.
The battery should have over-current protection as close as possible to the battery positive terminal.
All the other circuits(branch circuits) should have over-current protection as close as possible to the positive busbar.
The branch circuit over-current protection is intended to isolate a fault to that particular branch circuit.
The battery fuses is the last line of defense to prevent catastrophic failure.
This is an example of a fused busbar which makes it easy to follow best practice.

Easily and economically satisfies ABYC 7 circuit protection rule by mounting on a 3/8 battery post, battery switch or bus bar.

That is the where the battery is attached and the battery is fused as close as possible to the batterty positive terminal.

Hi Taffy,
The fuse for the inverter is to protect the inverter. You also need to fuse the wiring from the battery to the inverter. To protect the wiring from meting and causing a fire.
For a start what voltage system do you have, what size wattage of the inverter and what is the wattage of the largest appliance that you will be using.

Hi ausie welshman lol (tim tim)
Its. 12v system, 135ah battery and 500w inverter……im only going to be charging tool batteries, nothing to more than 28w charger

The fuse in your inverter is to protect the inverter. The fuse on your wire is to protect the wire. Yes you need the fuse on the wire.
