Solar-One Batteries with HuP. Technology
Heavy duty batteries for your renewable energy (RE) system!

Solar-One batteries feature a design that’s so unique, it’s patented. Engineers at General Battery teamed up with Dupont chemists to design a flooded battery that is so dependable, it’s backed by the longest standard warranty in the RE industry (7 year free replacement and 3 year prorated).

Solar-One batteries are very heavy and present special issues for the renewable energy installer. To put this superior technology to work for you, employees at General Battery designed an epoxy coated steel case that allows each 2 volt cell to be removed. This solved the weight issue and also Solar-One batteries with HuP. technologyoffers excellent protection against breakage while in shipment. Oversized lead terminals are welded to the battery posts allowing the use of lead coated solid copper buss bars as the cell interconnects. Because the lead terminals are so large and heavy duty, they provide excellent conductivity and a strong connection point for the cell lifting strap. All these features mean fast and easy on-site assembly, great energy transfer and the ability to remove and replace individual 2 volt cells.

The purchase of these batteries also includes an installation and maintenance manual written for the end user, and also the manufacturer’s written warranty. Solar-One batteries are warranted to deliver 2100 - 80% deep cycles and an estimated 4000 cycles at 50%, equaling more cycles and usable battery capacity. These offer a 10 year warranty - 7 year free replacement and 3 year prorated; these batteries have been in RE service for over 13 years, with a 99.8% track record in RE systems. These ship FREE to most commercial carriers with a dock anywhere in the lower 48 states (‘on the beaten path’).

The Solar-One positive grid is the heaviest in the industry, allowing for the maximum amount of active material in each plate and increasing capacity.  We have more specifications (and maintenance information) on these we can provide you regarding capacity and weight, so don’t hesitate to contact us for additional information; e-mail us at info@oasismontana.com.

Now in autumn, we are enjoying cool and wet (even snowy) conditions, but it was one hot and smoky summer and fall for many parts of the western U.S., and Montana was no exception. We were smug with our good snowpack, back in spring. Then our summer started with a week of 100+ degree weather, and continued to stay hot. We were blanketed in smoke from the horrific fires (1.3 million acres burned) until the middle of September, and unfortunately, many homes and a few lives have been lost. We have been able to help some people with water pumping to protect their properties, but our drought conditions and warm temps made for a very dry western tinderbox. If only those folks in Texas could’ve share perhaps 1/20th of their deluge from their state…

Even so, the garden and fruit trees kept us busy, and despite the smoke we still enjoyed camping, fishing, and canoeing in our local river (even though the water was quite low). We hope our legislators will work on commonsense future measures to mitigate the effects of warming temperatures and prolonged drought. One thought we have had (since we were less than a mile from our local small airport, a helibase that launched many helicopters and other aircraft for fighting fires) is that actual planning for these events would be a good idea (seeing as they are now part of our new normal)—how about reservoirs near these airports to make hauling the big buckets faster and more affordable? Here in Stevensville, we have several large irrigation ditches in close proximity to our airfield…. Well, it’s just my 2 cents worth!

Just a reminder, we offer a line of non-electric propane refrigerators, freezers, cooktops and ranges at www.LPappliances.com, and a line of efficient AC or DC refrigerators and freezers at www.eco-fridge.com.


The best nuclear generating station is 93 million miles away, and is available for pretty much everyone!
Thomas Edison quote on Solar Energy

Iron Edison Batteries
We also have a new line of batteries to offer, manufactured by Iron Edison;

Iron Edison BatteriesOver a century ago, Thomas Edison found a battery design that he considered to be nearly perfect. Today, Iron Edison is proud to offer an updated version of this incredible design that is specifically manufactured for renewable energy systems. Iron Edison carries a variety of nickel iron batteries: 12 volt, 24 volt, and 48 volt configurations, each configuration with amp-hour capacities of 100 Ah through 1000 Ah.

The International Trade Commission (ITC) is responding to a lawsuit brought about by SolarWorld and Suniva (U.S. module manufacturers) that low cost imported (i.e. Chinese) solar modules have hurt their competitiveness, so they are asking for a tariff on imported solar panels to ‘level the playing field’. Many pro-solar groups are opposing these tariffs, as they will increase the dollar-per-watt cost of installed solar power systems, and very negatively impact job growth in the solar sector – which had been bourgeoning in the past few years. In fact, it is estimated that 1 out of 50 new jobs is in the renewable energy sector. The ITC has approved tariffs, but it will be up the President Trump to set the rate; those of us in the industry are waiting to see what will happen, and many jobs are on hold pending the decision. It sounds like costs may go up 10% to as much as 40%.

             1912 Warning on coal cuasing climate change


  • When autumn darkness falls, what we will remember are the small acts of kindness: a cake, a hug, an invitation to talk, and every single rose. These are all expressions of a nation coming together and caring about its people.
    --Jens Stoltenberg
  • Designers want me to dress like Spring, in billowing things. I don't feel like Spring. I feel like a warm red Autumn.
    --Marilyn Monroe
  • The cost of solar energy has not been opened up because the oil industry does not own the sun.
    –Ralph Nader
  • The spring, summer, is quite a hectic time for people in their lives, but then it comes to autumn, and to winter, and you can't but help think back to the year that was, and then hopefully looking forward to the year that is approaching.
  • A kestrel can and does hover in the dead calm of summer days, when there is not the faintest breath of wind. He will, and does, hover in the still, soft atmosphere of early autumn, when the gossamer falls in showers, coming straight down as if it were raining silk.
    --Richard Jefferies
  • I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it's wireless!
  • I prefer winter and fall, when you feel the bone structure of the landscape - the loneliness of it, the dead feeling of winter. Something waits beneath it, the whole story doesn't show.
    -- Andrew Wyeth
  • There has been a systematic repression of solar energy. It seems pretty funny to me that the government, if it is completely neutral--why wouldn't they pursue this far safer alternative of solar energy with the same intent that they pursue nuclear energy? Solar power is the last energy resource that isn't owned yet--nobody taxes the sun yet.
    --Bonnie Raitt
  • The problem with winter sports is that--follow me closely here--they generally take place in winter.
    --Dave Barry
  • If we had no winter, the spring would not be so pleasant: if we did not sometimes taste of adversity, prosperity would not be so welcome.
    --Anne Bradstreet
