The image says 45W, not 450 in your list, and it also list the other parts draining power summing up to less than 300W. However, a medium storage battery won’t last long once the sun goes down.
At the bottom of the screen you’ve got a summary of how much your batteries are charged (9%), and when there’s a change there’s also an indication of how long it will take to fill/drain the batteries at the current rate. Since that indication isn’t there, my guess would be that the solar panel isn’t exposed to the sun (under a roof [as in a barn or building] or it being night), and the devices aren’t turned on (they’re off when built, so they have to be turned on manually).
Note that static “vehicles” have to either be outdoors or be hooked up to another “vehicle” via a jumper cable, so your freezer unit would be inside your building while the one with the solar panels and main batteries would be outside, either beside the building or on the roof. Note that I’ve yet to make such a construction, though.
