bupkis: I do have that page, but it looks like I can set the disconnect voltage from the BT app after all. You had mentioned that I needed to set the battery type to USER and when I tried that, I was able to change the values in the settings of the app. I changed the Over Discharge Volt and the Discharge Limit Volt to 12.0 before I went to bed last night. I wanted to see if the system would switch over to the AC adapter before morning, but even though the Battery Capacity was only showing something like 60% this morning, the Voltage was still well above 12.0, so I have now set those 2 parameters to 12.5 V, just to see if the system will work like I intended.
Thanks for your patience in waiting for me to discover that I need to follow your instructions to the letter. One thing I still find puzzling, though. The Battery Rated Ah in the settings screen shows 200 and even with the Battery Type as USER, I cannot seem to change it. I will change it to 50 and get a message on screen that the setting was changed, and it will say 50 as long as I stay on that screen, but when I close the app and go back in, it is back to 200. Maybe there is no reason to be concerned, but I would hate to think that the app thinks the battery's capacity is 4 times what it actually is.

Ok, I guess I don't need to worry about the BT app showing the wrong battery capacity. The BT transmitter has apparently died. When I open the app, I immediately get a message "Device Disconnected". When I go to the Device Info screen and choose Search Device, it will find my device, but when I try to confirm that is the device I want to pair, the app immediately returns the message "Device Disconnected" and does not seem to try to pair with it. The communication light on the device is not glowing and I tried removing it from the jack on the charge controller and plugging it in again, to no avail. Maybe I will have to return a piece of equipment to Renogy after all. I have checked that the Bluetooth transmitter on my phone is turned on, but there doesn't seem to be anything on the Renogy device that switches Bluetooth off or on, so I am left to conclude the device has given up the ghost.
