In Podcast 294 Paul, Rick, Jason, Steve Heckeroth, and Stuart Davis continue their review of the solar workshop. They begin by noting the power of one image on Steve’s presentation that demonstrated the massive amounts of solar energy the sun gave in the last 100 years compared to the tiny amount of petroleum we have used in the same amount of time.
The guys then get into discussing why they prefer DC loads, and what kind of voltages are appropriate for a house. They decide that 48 volts is probably the magic number considering a 48 volt pack can end up getting up to 60 volts.
Paul talks a little bit about the monetary technicalities of this workshop and how they might need to find a new, more economic way to run them.
Paul then brings up the love shack which is basically a tiny house, but even smaller. It is on a skiddable structure that he thought would do fine with 200 watt solar panels but that hasn’t exactly been the case. He brainstorms heating it with an incandescent light but realizes that would probably take up too much power. This leads them into a discussion of LED and incandescent lights. They talk about each of their benefits and drawbacks.
They go back to thinking about the loveshack and discuss the possibilities of using masts or just eventually moving it to a different place with the skids.
You mentioned lack of wifi signal reaching the love shack. I have had some success using a reflector to gain some distance in a particular direction, and you could even consider runnign them on both sides of your connection. A laptop typically wouldn't have an external antenna, but I use an external USB wifi adapter (free at a garage sale) so that I have an external antenna to use with the reflector.
In the podcast inverters were talked about. I have an Elec Trak tractor which has 6 - 6V golf-cart batteries wired in series for a 36V system. I'm having trouble finding a 36V inverter, does anyone have any recomencations? I know I could take a 12V inverter and put it across 2 batteries, but that would unbalance the overall battery pack. Any help would be appreciated.
Jerry, Cooper-Bussmann makes equalizer/converters that can be used to tap 12v off of larger voltage banks. Some are designed specifically for golf cart applications. The caveat is that they are pretty much limited to 100a DC output, which isn't much for an inverter. My advice is ditch the AC whatever it is you are trying to invert for, and find a DC powered unit that does the same thing. If it's a small load, the unit above may work for you.
My biggest use will be running an electric chainsaw but no one makes on that runs on corded 36V DC. Plus I would like to have the option of turning about 800 Amp Hours on wheels into a backup when the power goes out.
