  • The latest in solar and wind...



    Illegal in so many populated areas. Progress? Or governments gone berserk?
  • Re: Is The Party Over?

    I see one guy posting real numbers based on history while another posts numbers based on what an industry hopes to achieve. I am sure that blades may become lighter and more efficient and, probably, more expensive. That doesn't change the fact that optimal wind only blows a certain percentage of the time and we have no economical way to store energy.

    The Powder River Basin in Wyoming has virtually unlimited amounts of clean burning, energy dense, anthracite coal. We are the Saudi Arabia of coal. I am in favor of burning anthracite coal in a cleaner fashion. We can easily make carbon from coal....using either phosphoric acid or steam. Carbon is marvelous for removing pollutants. Thats my idea and I have spent at least five minutes studying it.

    It is human nature to very briefly consider an idea and respond with this mentality, "Well that idea isn't cheap or easy so we will poke fun of you as our response."

    Government will not solve our energy problems. Government is the problem.
  • Re: Frigidaire on modified sine power

    It wasn't many years ago that propane refrigeration was "derigueur" for off gridders. We have recently come so far as a result of giant, low cost panels.  Shoot....I run a full size refrigerator and two freezers. There are reasons for that...

    Reading the comments of those who have forgotten more than I know, it seems like pure sine wave is worth it. The smaller, lighter "high frequency" pure sign wave inverters are quite affordable and many of us have been quite happy with the results. 
  • Re: Cable Connections: Battery Bank

    I keep thinking freezers in Texas during the summer are possibly related to these problems. How hot are the rooms where they are located?

    Your charge controller, inverter, and batteries will all last much longer if you can figure out a way to keep them "cool". Heat kills electronics. For that matter, you can look at heat as generally "speeding up the metabolism" of most things. Thus shortening the life of food, batteries, chemicals, electronics and other things.

    You may have low humidity which, of course, helps with storage longevity issues.
  • Re: Problems getting the new Schneider/Xantrex C-35 controller to work...

    Have two solar challenges at the moment. Recent developments:
    Xantrex C-35 shows about 27.6 volts at the terminals. That may seem alright though it is , of course, having little impact on the 1650 pound battery. The battery voltage has risen from 24.1 to 24.2 volts in the past two hours. Maybe the controller is OK now while it was doing nothing while blinking red/green.

    48 volt bank survived the night with one battery bank instead of two. Morning voltage was 48.2. Still thinking of using it until it dies. Every month I squeeze out of it saves me ~~$75 in battery usage. Cripes....I could likely squeeze another year out of it by spending ~$400-600 on replacement batteries. Gee.

    Genset usage is OK. I just managed it improperly when I awoke, stunned, to a 1am power outage.

    Things are looking up today for sure. Yesterday morning was a nightmare. The controller was saying scary things like Comm Error etc. I was worried about a bad controller and/or inverter and/or genset. It was me being stupid.....out of practice.

    EDIT: Wrote this sometime yesterday and failed to get it posted.
