I have a few battery questions.

what kind of high powered electronics you have in your truck ?

 

Carrier APU has 6kwt 120v generator. its the best option for this situation...

 

And can also be purchased as generator only if you don't want the AC system for whatever reason

 

I will repeat what I said, it comes from a lot of years in electronics....


Get a generator.

Get a quality 10kw slow speed generator to give you clean and dependible.

Why?

Because when you are all done with the batteries, the cabling, the monitoring system and other changes, you will have spent more money and added more weight than it is worth it.

 

This is a job for a 120vac honda generator. Gas is cheaper than diesel and the honda engine is cheaper to replace than the truck's. For the amount of power you want there is no sense in wasting extra via inverting DC to AC and then replacing inverters when they die.


If you dont want a generator, and have a midroof sleeper, my advise is to put solar deep cycle batteries under your bunk and build a full roof solar panel wing. Keep the solar battery bank on a separate LCD digital volt display and have a connection between your starting batteries and your solar batteries that is interrupted by a solenoid. The solenoid gets triggered by voltage on the field wire of your alternator. This way you can run your play batteries dead without any load on yoir starting batteries. As soon as you start the truck, the alternator brings both banks up to 14.x at a pace that the alternator can handle via its own internal regulation circuit. You dont need a bigger alternator, you just need to give it sufficient time to charge up.

 

Ok The generators foot print is less than the batteries and simplify a lot.

 

will you drive, listen music and use the kettle? )))) your audio equipment is for 12v correct?
