My post was said with a 24 volt setup in mind. I can power a laptop, 32 inch lcd tv, hand held gaming consoles and lights through a 650W pure sine wave invertor. Keep in mind that I do not power these all at once but the original post stated a 'very small bar fridge', rather than give something away, why not ask someone who knows these things such as www.springers.com.au
who are the 12 volt and solar specialists.
An engel/waeco is $900 plus which the sale of a bar fridge will obviously not cover yet that money may contribute towards a battery/invertor setup that can be used for other things in the future.
Ultimately, and engel/waeco is brilliant but these things arent always high on the list of purchases due to the cost.
