Hi Jon_k welcome the forums
you cant use the 600V wire, it would melt probably. lol
you will need to use a 2 awg quality wire with a 75 amp fuse as close as you can get it to the battery.
50 may do but if you get a direct short it will blow a 75 amp pretty quick also. that way it wont blow unless its a direct short.
the ground you can terminate as close as possible to the inverter.
just drill a hole and grind off some paint to get to the metal on the body if you cant find a bolt close by. try to stay no longer then 18 inchs.
so you dont need to run the ground all the way to the battery.
and you dont need to ground the battery if it has a decent ground wire running to the body from the battery.
for the 110 volt plugs up in the dash i would use a flexable 12 gauge wire found in most automotive or stereo stores.
solder your connections so they dont come off ever and seal them so you will be sure they never groun on the dash metal.
hard telling what all 110 volts will do to a 12 volt system, but i promise it wont be good.
the liquid electrical tape works well but be patient and use plenty of coats of it. just look carefully and double, triple check all connections beofre applying power to it.
you could use the 600 volt wire for the plugs in your dash but it would be hard to work with.
and make sure you dont ground the 110 side of the inverter into the 12volt system, its not the same.
you can get a one way electrical switch which will only allow electricity yto travel one way and not back, however the more complex you make it the more things to go wrong.
i let my inverter sit for 2 months without starting my truck and had no problems.
what i would suggest as a cheaper route would be a smaller pulley on the alternator.
easy swap and gets you more charging power, you should be fine with one battery with that inverter.
the inverter has a low voltage cut off anyways so it will shut itself off before your battery gets so low you cant start your truck, assuming it fires up ok and doesnt need to be cranked over 100 times.
let me know if i can answer any other questions, and post pics of your project as you progress.
very cool, i love my 110volts in my truck
