Those voltages you refer to are the specs for the LOAD connections of your SunSaver. These are normally connected to your 12V fuse panel. The load connections will disconnect all power at 11.5V, and reconnect when the battery is charged up enough... which it deems to be 12.6v.
Those voltages have nothing to do with connecting or disconnecting the PV panel. It is always connected.
The manual (page 40) - https://www.solar-electric.com/lib/wind-sun/SunSaver-manual.pdf says that for 12V AGM batteries, the voltages are:
Absorb - 14.1
Float - 13.7
As regards to the BMV not showing charging current, I suspect you have a wiring error on the shunt. There should be only ONE wire connected to the -ve terminal on your battery, and that goes to the shunt terminal labeled "To battery". ALL other ground wires should go to the other side of the shunt, including the output of the Sunsaver.
Does that make sense?
