Hi All,
I'm planning to pull the trigger on 2 16" 2/0 cables to connect the battery and the inverter tonight.

Am I on target here?
I'm still trying to figure out if I can use my existing 4 gauge wire to connect the house and the starter battery (?), and how much 8 gauge wire I need for the alternator swap etc. (I've been re-reading Mex's / various posts - I think I may need to pop the hood tonight and measure ?) ...

Use a fuse with that 2/0 cable.
I have this:

type of fuse holder. I needed an 8" red cable between this and the battery. One problem is that I had to tape the cover on the fuse holder because the the 2/0 cables were too big.
This may not be the right type of fuse for the 2000W inverter. I use 250A because the max Amp spec for my 1000W is 133A. I would allow at least enough to cover the 4000W peak surge of your inverter. 400-500Amps would protect the 2/0 cable and allow maximum use of the inverter.
I believe the 4Ga cable will be adequate to pass charge current to the Lifeline.
With the engine off, and a battery separator like the Sure Power 13-15, the inverter Amp draw will be limited to the Lifeline. With the engine running, the draw will be shared. Just don't have any extra length coiled up.
Run the numbers through the wire sizing site.
HTH;

OK - sounds like I'm on target with the 2/0 wire, and I need to add a fuse (so - two 8" cables on the red, yes?).
Perhaps I can find a fuse that's better suited for this (so I don't have to tape etc.)? Suggestions?
Also, in the current setup I have the black terminal on the inverter connected to the body of the van. In the new setup with the lifeline, I am connecting it to the black terminal of the battery, yes?
Thanks,
L
PS I will wait to post solar pics/ideas until the cables are set, to keep things simpler
