Voltage drop on inverter
I have a Samlex 3012 inverter charger that is powered by 4 x 100 ah LIFEPo4 batteries. Each of the batteries is wired separately to a bus bar using 00 welding cable, this bus bar feeds another one tha...

based on the reading from the marine website. it says to fuse for the size of the wire, not for the load on the wire. fuse can cause a voltage drop even when working properly, never thought of that till he mentioned it.
glad to see the voltage drop test worked for you, it found something for me as well. just learned about it a year or 2 ago, and i thought i knew alot of about electricity.
Fuse tutorial.
"#1 Fuses should be sized to not exceed a continuous current of more than 80% of the fuse or breakers rating. Doing so will lead to short fuse or breaker life and the potential for nuisance trips. It also leads to excessive voltage drop across the fuse.
#2 When sizing for charging systems it is often best to use a fuse that more closely approaches the maximum ampacity of the wire. Doing so will still protect the wire but will also result in less voltage drop across the fuse. In other words it will be helpful, from a voltage drop perspective, to use the largest size fuse the wire can handle. Doing so will minimize any added voltage drop across the fuse."
