1 amp = ?? Watts?
Watts = amps times volts

1 amp at 120 volts = 120 watts.

The 160 watt solar panel will product 160 watts of power in direct sun, with 90 degree incidence on the panel. Since this may only happen for a second or two on any given day (without a gear driven solar tracking mount), you will get much less than 160 watts during periods of sunlight.

Of course at night or cloudy days you won't get much if any charging. So, on a sunny day you can expect about half the rated output of your panel (or less on a cloudy day).

80 watts is better than none. but will not replace what is used all day. The generator will still be needed; just less often.

If I only run the outside fridge for 3-4 hours during diner time, would I still need to turn on the generator?

I guess it would depend on how warm the inside of the fridge got the other 20 - 21 hours of the day. The fridge would be running constantly for those 3-4 hours till it cooled everything off.

The solar panels will be running at 1/2 efficiency but all the time. So when the inverter is not supplying power to the fridge, it is charging the battery. I think you will be fine; with the generator for a few hours a day.

Suggestion that I see guys do at the NASCAR races if fridge has little freezer in top get unit cold by plugging it into 120 source along with whatever will be in it. Then put a couple peices of dry ice in freezer they claim keeps cold for days

Mine recently quit working, it runs but does not get cold or even close to freezing like it used to? It has vents into the trailer so even with the door closed it should have enough ventilation... Any ideas?

My ok does not have vents so even that shouldn't be an issue.
Sounds like the fridge just might be headed south.
