50 Amp hours @ 12 Volts does not produce much power: 300 Watt hours DC maximum. This definitely will not run a refrigerator for 6 hours, much less anything else on your list. A typical refrigerator will use 1.2 kW hours per day, and it is highly variable with the exact unit and conditions under which it is used. 30 Watts of LED lighting for 4 hours is 120 Watt hours alone. Plus you have to power the inverter which would supply the 120 VAC.
Two 65 Watt solar panels would be able to charge about 75 Amp hours of battery, but again that is not enough to do what you are looking for.
Before you buy anything else, buy a Kill-A-Watt meter and measure the power consumption of anything you want to run from solar. It is very important to know how much power you need to supply before trying to find a way to supply it.
1220 Watts of PV, OB MX60, 232 Amp hrs, OB 3524, Honda eu2000.
Ohm's Law: Amps = Volts / Ohms
Power Formula: Watts = Volts * Amps
