Merging a Xantrex SW2024 to a Tesla Lithium battery

This is a wonderful example of thinking controlled by the “box.” Until Mr. Wizard threw out the idea of shutting off the AC going into the Xantrex, I was completely focused on breaking the link between the charger and the battery as my “safety valve.” This solves a major problem. By the way, no the BMS is separate from the Tesla battery. The Tesla BMS isn’t suitable for our application. Thank you for a wonderful suggestion. I don’t think I ever would have thought of such a simple solution.
