General wiring misunderstanding on Nash22H
Hi, I have a 2001 Nash 22h that is new to us. I just modified battery brackets to accept 2 new Trojan 6V T105 batteries. At same time I installed a Pico master disconnect switch rated for 300A continu...

Also consider the Peukert Effect when sizing battery banks.
You can have a .7 volt drop or even say a 1.2 volt drop over the circuit and still get the battery charged. The problem is that it's going to take longer.
As Drew said, all the energy is there but some of it is being lost as heat when the conductors are too small or other resistances are in the circuit. If you were to plug the rig in while stored and come back days later, the battery will still be charged while having the voltage drop. It will just take longer. That's why when running a generator for example you want the system to have very low voltage loss. Saves fuel, wear and noise.
Of course the same is true for solar because you are trying to extract X amount during sun hours. If a large amount is lost in resistance during the given hours then it doesn't reach the battery before sun down. If you were out boondocking for a couple days and you go plug in and your converter only goes to 13.6 volts or the wiring losses hold you at 13.6 volts, the battery will still get charged but it will just take longer.
The same is true of taking energy out with your inverter. If the wire is undersized energy will be dissipated before going to power the device.
The loss in the wiring is your gasoline and wear and being dissipated by the small wire so to speak. The noise portion of the gasoline is being absorbed by all of our ears.
Three things about resistance. 1. Length of the conductor. 2. Size of the conductor. 3. Temperature of the conductor.
The things I have told you are from a boondocking perspective. If you are plugging in after using your rig for weekends or just a night you may be fine with smallish voltage drops because time isn't an issue for you. This is not to say that a poor crimp or bad connection that causes resistance is ok. That poor crimp or bad connection could be a fire or battery explosion hazard if enough amps are pushed through it.
