Portable Solar Power

[Straight Shooter]

Hi guys n gals, I need help, although I have some solar chargers for batteries and mobile phones etc. I am now looking for a portable type set up, I have seen 1 on ebay for about £239 but I have NO idea on what I should get, the setup comes with a solar panel, deep cell battery,inverter with all the leads , just plug in the leads and off you go 3000 volts will run a light or fridge. Now then I am no sparky ,not got a bloody clue , can anyone tell me what to get , keep it simple, like talking to a 6 year old , I would be most grateful for any help, from a money point of view , I have no budget as such but I want something up to the job. many thanks ss
