After solar goes dark, the battery voltage goes down too not just the current from solar.
The inverter needs voltage from the battery to work and has a low voltage shut off. If your wires from inverter to battery are not fat enough for their lengths, or if you don't have enough battery to hold the voltage up with that inverter draw when the battery is starting out at less than full (which it acts more like full with the solar backing it up in the daytime) then you will go below that voltage shut off when trying to run big things off the inverter.
