Here is the drawing, BUT I do not know enough about the inverter purchased needs or the vanner out put....if the vanner is a 10 amp output...I do not think that is enough to power a 3000-watt inverter. I think the most a Vanner can put out is 50 amp...if that's the model installed.
Further, if all that is being powered is a tv and a few lights and smaller items a smaller inverter would do the job.
Would a smaller inverter drain the battery less....i don't know without further research....i know a 400 watt inverter will eat a car battery (with the motor not running) powering a lap top in not much time at all....the cooling fan eats more battery than the laptop computer.

to get 100 amps you need two vanner converters....like i said.. i don't know enough about the limits of the vanner or the inverter...

you could just wire it and see what you get...

i just wouldn't try all the loads at once ...

Jim -  keep in mind that the catastrophic fuse is for the battery bank only.  The inverter would be best fused on the + side.  Any device running on the DC side should be fused on the + side with the batteries fused on the negative side.

Sean,

I'm tempted to give up trying to understand the system you are proposing, but perhaps it has not yet been adequately explained. The 2/0 cables from my battery bank go directly to my inverter. You had me persuaded to move the 300 amp fuse in that circuit from the positive side of the battery bank to the negative side. The much smaller wire (4g I think) to our 24v and 12v loads is fused separately on the positive lead. Now you tell me to fuse the inverter on the positive side.

I don't see how it is possible to fuse the inverter without also fusing the battery bank. You want to take another crack at it?

You can get roughly 500 watts out of a Vanner after losses through the inverter, so that's a little silly for a 3,000 watt inverter.   It won't work well at all.  Either toss the current inverter and get a 24 volt model, or work out a way to supply 12 volts from a dedicated alternator.  Or get a 500 watt or less inverter.  You need to calculate your loads to know which answer is right.
