I have a FWC fleet with a 1314A battery isolator which I'm looking to change out with a Blue Sea ACR to increase efficiency.
I've been thinking about the operation of any ACR or battery isolator, and perhaps there is an important gap in my understanding of how they measure the voltages of the vehicle and house batteries, can someone please clarify/confirm?
If the engine is running and ACR/isolator is connected and the batteries (house and vehicle) are charging, all is good. When the vehicle is switched off, the voltage at the ACR/isolator will drop and the house and vehicle batteries will be disconnected.
However, if there is a solar charger on the house side, then the voltage as measured at the ACR/isolator will remain high, and the batteries will remain connected until the solar charger also drops its voltage?
My assumption is that when connected, the ACR/isolator cannot differentiate between house and vehicle battery voltages until they are disconnected? Is this correct or is there some clever way they can that I don't understand?
Thanks for the education!
