Cost of a dual battery system ?
Jip, this is another one of those questions that pop up OFTEN.
The big ticket items is easy to price, 10 minutes on Google on this 9th day of June 2014 provided me with the following prices. I did not phone around for best prices, I did not check quality, so this is just a rough guide :
12V 12A dc2dc HcdP – R 1 250
12V 30A dc2dc HcdP – R 2 575
Ctek 250 S – R 3 900
80W solar panel – R900
105A.h deep cycle maintenance free battery – R 1 500
It is easy to think the cost is 3 900 + 900x2 + 1500 = R 7 200 ... NOT SO !
The cables aint cheap, and if you are going to buy it "by the meter" for a small project you will be paying PREMIUM prices !
Those silly little connectors - I paid R3-90 EACH last Saturday !!
From R50 PER Brad Harison connector !!
R35 for the fuse holder, then another couple of notes for the fuses ..
even now the LED lights are another couple of hundred rand ...
the list of "small stuff" just does not stop ....
And if you want it installed ... well the old saying "You get what you pay for" is ever true !! To do this type of installation PROPERLY is VERY labour intensive !!!!!! and labour aint cheap .....
If somebody charges you a "few hundred rand" to install a complete system, including solar panels and distribution setup ... uhm ja, either he is getting the parts at a massive discount or he is going to cut corners ...
