charge controler, too easy

hi everyone, I just finished working on one of my small battery banks. every time I work on one  of my banks its so easy because of the controllers and its configuration , vary simple 4 wire install-- pos / neg and the pos / neg for the dump, 18 awg that's it. no cables or anything else to play with.the controller is made by windandsunpower.com and is also the cheapest iv found. I use the ssr relays and it makes every thing so easy. if your using one of the 440amp mechanical relay type controllers ,you really need to check this out, you will never go back to mechanical relay type again. the accuracy is amazing and will hold to .04 volts on the smaller systems and .06 on a 55amp system, iv never seen or herd of any better. I love this controller and would never think of using any other. check it out. thanks for reading.
