Okay folks, I am going to re-iterate. The fridge is set to shut off at 11.4V, this is the "medium" setting as per ARB manual. The Fridge will restart at 12.2V, which would be when alternator is supplying. The dual battery management system is voltage isolator design, where it senses if main battery has 13.4V, which would be yes. If this voltage drops below 12.7V on the main battery when alternator is running, it stops feed to the optima yellowtop and feeds to the main starter battery.
I have not reached 10.5V ever, but I have mentioned this voltage due to confusion over what is considered deep discharge, Optima themselves say that a 10.5V is deeply discharged, but as per the ARB fridge it would not let the yellowtop reach that due to the setting on the fridge.
Diplosat, that power bank system is phenomenal, but for me it is a no go, 600AH with 500W of solar. Reason is that we drive 90% on sandy desert terrain, where every extra kilo works against you. We also do not have the same retail expertise, for example, just yesterday I talked to the sales person for the Optima batteries, and he kept suggesting that I use a normal battery, I don't believe he knew that I needed a deep cycle to run my fridge, and don't need the FLA's mass current in bursts for the fridge.
The ARB fridge has a 0.87A/hr rating as per their own website.
As I limited in space and don't want to add more weight to the car, I am going to change the way that I use the fridge.
