Hi,
If the alternator is 160 amps the most you want to "send" to the inverter batteries, on a continuous basis, is about 40 to 50 amps. I'd suggest a continuous duty solenoid in series with a 50 amp automatic circuit breaker. Use appropriate wire size.
I'd far rather replace the circuit breaker than replace the alternator.
I prefer to be "in control" so I have toggle switches that activate my solenoids. By doing that I have a "poor man's boost system for the chassis battery. It also allows me to "give the alternator a rest" if I feel it is working too hard.

I had a RV shop wire it for me earlier, but the only used a 100 amp isolator which did not last long. (alt. is 160 amp) I have it hooked up now with a 200 amp battery isolator, but sometimes my inverter goes into a default mode. I am scared it could do permanent damage to the inverter.
