Recommended Fuse Size Missing from MultiPlus 500VA - 1600VA Manual

I've just been reading the Wiring Unlimited document and in section 4.1 it states:

Though this does not appear to be in the Rev 06 MultiPlus 500VA - 1600VA Manual:

I've scoured the document for "recommended", "fuse size" etc and cannot find any references for this for any of the models

Is there a reason why these are excluded from the manual here as I'm missing or misunderstanding something?

Specifically I'm looking for the 12/500/20 recommended fuse size if someone knows that in the meantime.

Thanks.

@netweb

I suppose because most people who buy the smaller ones dont fuse? Just guessing.

Anyway there are different types of fuses for DC. 500va ÷ 12V is 41.666A so a fuse rated for that will work.

16mm²cable fine strand battery cable can carry 100A. So 100A one will work as well. Since fusing is there for cabling I would go with that. The victron midi fuse has a neat one in that range

Thanks, I've gone for a 63A Noark DC Circuit Breaker where I'm using 100A cable from the inverter DC output to a positive busbar
