Yes, any battery can have a PV solar system added as a charge source. The amount of solar power needed depends on where you are located (temperatures and insolation), how much power you consume and whether you use other charge sources like a generator.

You can add an inverter to your battery but 1000 Watts on a single 12 volt battery may cause too much voltage drop and the inverter will turn off. It depends on the load.

If you can find another used battery or batteries like the one you have, you can mix them. This is not the best but it will do if on a budget. I don't recommend buying a new battery and mixing it with an old battery. That will cause early failure. Always use the same make, model and age battery when you buy new.
The refrigerator, if it is a propane/electric, is a very heavy to use on 120 volts. Use the LP setting and save your battery for the other items you mentioned.
If you plan to use this full time, you should also install a battery capacity monitor that will keep track of your remaining battery capacity. Blue Sky Energy makes the IPN Pro and it works with their charge controller. No other monitor/charger combination on the market can come close to the performance and accurate battery charging it provides. There is also Bogart Engineering, Xantrex and a few others that make capacity monitors.
