those with the Xantrex Freedom XC2000 inverter…

Great post, Craig!

Battle Borns gone.  Epoch’s installed.  Hold down straps aren’t on yet.

Mike, very happy for you, on your 600 Ah upgrade!

It looks like you used the bolts that came with the Epochs on all 4 posts. I found when the 4/0 lugs were doubled up that the OEM bolts only had a few threads to hold on. Yours might be fine, depends on the thickness of the lugs, but on two I used M8 bolts 5mm longer (see pic).

John, thanks.  I’m using 2/0 cables.  I asked the Epoch guy and he said 2/0 or bigger.  I also have some longer M8 bolts that I ordered just in case.  The bolts that came with the batteries work fine.  I’m happy with the upgrade!

Excellent Mike! hard to determine cable size in a picture.

It’s more the load to spec wire gauge and fuse amperage vs. battery type or Ah. If you have a 2KW inverter, 2/0 wire and 250A fuse are fine. 4/0 wire and higher fuse amperage are required to run a 3KW inverter at full capacity. 😎
