Greening Your Home - new solar system, Battery not charging??

Hi, I am having problems with my solar system not charging the battery?? Im new to this so sorry if its something simple. I purchased my solar system from here, http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=250287012207 I also purchased an additional 10w solar panel and I have replaced the battery with a larger battery that is 12v 9ah.

I have daisy chained the 3 solar panels and connected them to the regulator. I then connected the new 9ah battery to the regulator, and also connected the inverter to the regulator (I did not turn the inverter on). I then left the system for 3 days so it could fully charge the battery. On the regulator there are 3 lights that show you how charged the battery is. For some reason only 2 lights show, never 3??? Even after 3 days of charging??

After the 3rd day I turned the inverter on and did not connect anything to it at 8pm, and at 1am the battery died / ran out of juice (Only lasted 5 hours)?? The inverter has a fan in it which must of drained the battery. But how can this happen?? Surely the inverter doesn’t need that much electricity?? I read the manual and it says it used very little power?? So I am confused as to what the problem is??

I guess the battery not charging properly ??? Any ideas what I can check??

Thanks
