As far as I understand the 70A rating is for the 12V output, so you would want a 35A maximum fuse for the 24V input.

Thank you for your help. Just want to have everything protected at the battery box and done correctly. Will use an ANL fuse and holding block for this . Thanks again.

One might consider: 85 watts max output at 12V

Puts out max 1020 watts. Divide by 24 = 42.5 amps.

I’ll be using 40 amp fuse on my 24V Lynx to feed it.

I’d put 80 amp fuse where it feeds a Lynx to distribute 12V.
