I'm so glad the state forced me to hook up to that reliable grid... OK so they told me I had to and I didn't... http://abclocal.go.com/kfsn/video?id=7238715http://abclocal.go.com/kfsn/story?section=news/local&id=7240825
Quote from: Squirl on January 29, 2010, 01:55:07 PMIt depends on how off brand you are willing to go and how much risk you are willing to take. There are many 40 Amp charge controllers on ebay made by smaller wind and solar energy companies that can be had for under $100. Many have good feed back. Here is one I have been looking at.http://stores.ebay.com/Coleman-Air-PartsPersonally for such a small system that doesn't get regular use, I probably wouldn't go so high end, but that is just my personality. A 1500 watt square sine 12V inverter can be purchase for $150. You could by 4-5 of them for the price of the Xantrex.
Quote from: muldoon on January 29, 2010, 01:49:55 PMI'm interested and learning here also. I have not built a system, just read on it, my input does not come from experience. I went to google Sams GC-2 for power storage and the first link I found was pretty clear that the lifespan of these is in the ballpark of a year. While saving money (up front) is great, it might not be soo great to replace them every 12 months. http://www.power-talk.net/golf-cart-batteries.htmlOur Experience with Golf Cart Batteries The third set of batteries to store power for the Ranch was a set of Sams Club GC-2's. We had two sets of eight hooked in series and then each bank was connected to a buss bar for a 420 AH capacity. These lasted 12 months. Thinking that maybe we just got a bad batch, we tried the same thing again. Twelve months later we were again looking at 16 depleted little batteries. We kept them charged, watered and clean and didn't abuse them with microwaves and such. The largest DOD they were subjected to was 35% with the average more like 20% - 25%. Even if you considered each day for a year as a "cycle" that would be only be 365 which is short of the average 500 which we see on a lot of charts. If we had been hammering them daily with high load devices, this might be understandable but the typical draw we have is in the 3 - 10 ampere range. One thought was that we should have added another bank of 8 the second time around, for a total of 24 to ease the average load per battery.

Quote from: pagancelt on January 29, 2010, 12:05:26 PMI have an DC electrical question.We have a Sundanzer DC electric fridge and we're planning on moving it a little farther away from our power supply. The manual says we should use 12 gauge cable for the distance we'll be at and the fridge comes with a fairly short 14 gauge cable. Should I just get 12 gauge to run from the DC box to the 14 gauge fridge cable, or should I replace the 14 gauge with 12 gauge for the entire distance? To be perfectly clear, do I remove the 14 gauge from the fridge and wire in the 12 gauge directly to the fridge?Thanks,Dave
Quote from: OlJarhead on January 29, 2010, 01:13:15 PMWOW! Just read that the Sams Club GC-2 is $66 at most places and can be found for $44 in some places (Costco maybe?)...in any case that changes my above cost considerably if I went that route.
Quote from: pagancelt on January 29, 2010, 02:45:28 PMThe 12 gauge will be running roughly 10 to 12 feet, if I don't change out the 14 gauge. If I change it out the total for the 12 gauge will be about 16 feet. I guess I'll have to pull the fridge out and see how difficult it'll be to change out the 14 gauge.Thanks,Dave
