Inverter install

Hello,

So we are dry camping for the first time and I am going to install an inverter for small electronic gadgets. I have my house cables going to a disconnect switch and a block stud. From the switch and stud the cables then go to my battery bank. My question is, could I simply run the cables from the inverter to the disconnect switch, stud? I would prefer this method? Or would I have to run the inverter directly to the battery bank? The inverter is a 600w pure sine, would I need some sort of fuse? Thanks all in advance and my apologies if question is repetitive. Additionally, would I need two in-line fuses or just one? I have a pair of 6V batteries?

    my inverter is mounted above the battery box. I used 1 gauge cable with a run of about 10 inches. Both cables run through rubber grommets coming out of box. I felt a fuse was not necessary.

    I'd prefer connecting direct to the battery bank with a fuse at the positive terminal. The inverter should be kept as close to the battery bank as possible without it being in the same compartment.

    If the inverter is right there and the wire is short and in plain view with sufficient ampacity I would skip the fuse. If the wire is longer than a couple feet or twists into blind areas or through a panel then I would have a single fuse on the positive side close to the source(switch stud).

    The closer your inverter is to the battery bank, the shorter and the heavier gauge those cables are, the better. Here's a cable gauge guide that may help ... and yes, you should properly fuse the + cable feed from the battery to the inverter.
