What size fuse
Going to add a 1000 watt pure sine wave inverter. Want to install a ANL fuse between inverter and battery. What size fuse should I use? Will be nothing more than Cpap machine or tv.

Assuming #4 or #2 wire I would be about 125 to 150 amps.
If you are going smaller on the wire the fuse would need to be reduced.
Neither #4 (85A) or #2(115A) will safely carry 125 amps.
What does the mfg. recommend?

I assume your ampacity is bundled 60C building wire as romex or in conduit.
Doubt the OP will see more than 30 amps with the load described. Still I recommend a proper install to use full capacity because usage may change.
