I got most of my components from Arizona Wind and Sun, 5 years ago.http://www.solar-electric.com/sobomp25ampc.html
There are many other options, many with better pricing. A few months ago I added a thin film 68 watt Unisolar panel(epvl-68) that I bought from Amazon.
Blue Sky 2512i controller( wish I bought the ix model)
Blue Sky IPN pro remote ( battery monitor and voltage adjuster)
Deltec 500 amp shunt.
Kyocera 130 TM panel.
I bought the 8 awg cabling from panel to controller from http://genuinedealz.com/
The Kyocera has a junction box. The unisolar uses Mc3 cables. I bought a 50 foot 10 awg MC3 extension cord, from Amazon.
To power a small 12v compressor fridge indefinitely, 60 watts in a sunny environment will do it. Using an inverter on a residential fridge, make that 80 or more watts.
