zero-point energy

You'll find a zillion discussions of this nature.
It's the sum of the losses in the system.
It's a complex calculation, but you can measure it easily.
Build it.
Disconnect both the inverter and the charger from the positive
battery terminal.  Insert an ammeter.  Measure the net amps flowing out
of the battery.
Calculate the hours from the amp-hour battery capacity and the
meter reading.
Sure, the amps will drop over time, but you'll get in the ballpark
with a simple calculation.
