So what are the benefits of 12 or 24 volts.I was going to build a 12 volt system with about 300 watts of pv panels. Thanks Tom Hi Digg

If you really want to buy some documentation to have it all in one place, there's a link near the bottom of this post that has a kit of solar and wind books that people seem to enjoy. It's affordable and you can get your money back if you don't like it. (but don't wait to report that) I can offer you lots of free help instead though. :) It just involves a lot of back and forth with questions and stuff... Here we go ! : Are you planning on a 12 volt battery bank ?? With 6 batteries, that seems to be the only combination that works. (These T105's are 6 volt batteries, right?) The reason that's my first question, is because it's rare to see 175 watt panels that output for 12 volt charging. Usually panels over 100 watts are designed for 24 volt batterybanks or more. All that means is that you need either 2 more batteries, or 2 batteries less. :) Let me know and I'll send more details about the specifics of what is needed for your project. DigitalMind Hi Tom,

Cost wise I was looking at purchasing 6 trojan t-105 6volt 225 ah batteries and connecting them in series. I would like to power them with a couple of sharp 175 watt blemished panels I saw if still available . anyway I would like to be able to build out about 350 to 400 watts from the panels. Ultimately I would like to be able to operate the two misting fans a couple of florescent lights and if possible be able to filter the water in a small 8000 gal. pool in the event of a major emergency. Don't know if this is possible on the same system as it seems that any option for the pump would required a 12volt pump for efficiency also after reading a couple of articles I'm thinking it would be better to spend the extra money for a true sine wave inverter instead of the modified one I mentioned Thanks again Tom hi Digg

If you're connecting a 3000 watt battery bank to this inverter, then no ! When an inverter is turned on and connected to a battery bank, even if there is no load, it's using power. The bigger the inverter the more power it wastes while turned on, so you don't want to get an inverter that's WAY more than you can handle, but you do always want to get an inverter that takes into account some future expansion... so basically it all comes down to how big your battery bank is and how much "recharge power" you have (in solar panels, or a generator, or whatever). Give me more details, and I'll send you more too ! ;) Hi Tom,

My question is I have seen a modified sine wave inverter at harbor freight tools that is 2000watt / 4000 watt surge this is larger than I would need but if i wanted to expand the system i would have the capacity . Is it alright to use this size an inverter in a small system ? Hot in the arizona desert thanks Tom Digg

I'm looking into how I can store power generated from solar cells and maybe even a steam engine. This post has given me some essential tips. Cheers, Simon Thanks a million for this article.
