Disconnect Alternator from House Battery Charge

I wanted to disconnect my alternator from charging my house batteries while I drive. Is there a simple connection or fuse located in the Battery Control Center or other location that I can simply disconnect?

If I turn off my battery disconnect switch, the alternator does not charge the house batteries. Disconnecting the main ground wire on the battery bank would also do it.

Why some ask.. I just upgraded to lithium house batteries and solar. The 2 reasons i have are
1. Per Battleborn, RV alternator cannot fully charge batteries (Alternator charges at a lower voltage.) I do not ant to run the risk of damage to my Alternator or batteries if possible without having a solution. The solution recommended to me was to buy a DC-DC converter to take care of issue. I dont have the $400 plus for the recommended part at this time.

2. Our solar can keep up with our demand, & we have a generator with the proper converter that can charge the lithium batteries if needed.

My thinking is to disconnect the current Alternator from the Control Center so I do not charge the batteries OR potentially damage one or the other UNTIL I get the funds or push comes to shove and I feel I need the alternator to charge while I drive.

To change the alternator on my FR3 was just priced at $500 for the Alternator & $200 Labor. I dont want to pat that either.

Im open to suggestions just trying not to break, or damage items if I can avoid it.

Put a switch on the BCC isolation solenoid coil. If it can't energize it won't charge the house from the alternator.

Disconnect...

Thanks for the explanation, Robo44...this is way above my expertise, but extremely interesting in any event. ScottBrownstein's suggestion sure sounds like a good option -- otherwise the master disconnect as also suggested above should do it? Please report back as time evolves to let us know how the system is working out for you -- it sure sounds great!

There is also a circuit breaker under the hood. It is mounted just beyond the grill. It should be visible as soon as you open the hood in the front left corner. That is the connection from the Chassis system to the house system. Either open the C/B (some have a button to do this) or disconnect the heavy cable from the C/B to the chassis battery.
