I think what's happening is my charge controller doesn't react too terribly quickly to a voltage spike at the battery while they are receiving a strong solar charge. A voltage spike occurs in my instance from dropping a load from my inverter while the batteries are approaching full and humming along at the bulk/absorption setpoint. Combined with that is the fact that I have a cheap inverter that probably does have components designed to have a high voltage disconnect fault at 15V, but since it is made on the cheap it has a large standard deviation and it trips at voltages approaching but less than 15V. A temperature compensated charging voltage, as well as the slow response to a voltage spike from dropping the load on an inverter, will approach or exceed 15V and my inverter trips.
