6 Burner Gas Range


NATURAL GAS AND PROPANE APPLIANCES: We got into these as a sideline to renewable energy, as most homes away from utility power use propane or natural gas for heating loads (like cooking, hot water, space heating, clothes drying and sometimes even refrigeration). Yes, it’s still fossil fuels we’re utilizing—but natural and LP gas are among the cleanest-burning of all fossil fuels, and are highly efficient for many appliances (and may be much more cost-effective than thousands of dollars of solar modules). 

So whether you want a sleek European stainless drop-in cook top, a small propane refrigerator, or an attractive 6 burner stainless range, you may find what you need on our web page at www.LPappliances.com - - even if you don’t want a solar electric power system!

And if you are seriously considering an investment in renewable energy (or are trying to simply help keep a lid on your utility bill), the first step is to become as efficient in your use of electricity as possible. If you have a lot of older appliances, an investment of several thousand dollars will save money with a quicker payback sooner than a similar investment in a power system. The first step is efficiency; look for the energy star label when you visit the appliance store. You can view our goods at www.eco-fridge.com  An investment in energy efficiency is always cost-effective! For basic information about efficient appliances and more, visit www.aceee.org



TriStar charge controllers

The TriStar is the newest addition to the Morningstar line of pulse width modulated (PWM) charge controllers. It’s a serious UL listed controller for 12, 24 or 48V systems and is available in 45 or 60 amp capacities. Unlike Morningstar’s other chargers, the TriStar cannot operate as a charge and load controller at the same time. It can be used as a diversion controller for a wind or hydro system where it will dump excess power to a heating element to prevent battery overcharge. The TriStar is conduit-ready with large #2 AWG wire terminals and it mounts readily on existing power panels. It can also be connected directly to a personal computer via an RS-232 port for data logging or remote system monitoring. Options include a battery temp sensor and digital meter that displays battery voltage, charging amperage, battery temperature, cumulative amp-hours and system status (in your choice of 5 languages—English, French, German, Portuguese and Spanish). Dimensions are 10.3”H x 5”W x 2.8”D and weight is 3.5 lbs. Also, the Tristar’s printed circuit board is conformably coated for protection against humidity and insects. It has a built-in high efficiency heat sink for cool operation and maximum reliability. Microprocessor controlled self-diagnostics are available to alert of system problems. The optional TriStar Meter is very sophisticated and informative; it’s a 2” x 16” display, and mounts to the controller, connected by a RJ-11 phone jack. One meter option includes 30 meters of cabling for remote monitoring. All Morningstar products offer a five year manufacturing warranty. For additional information on this and other charge controllers and regulators, visit our web page at: www.chargecontrollers.oasismontana.com  
If it’s time to upgrade, consider the Tri Star!

The United States has tremendous wind energy resources. Although California gave birth to the modern U.S. wind industry, 16 states have greater potential.

Installed wind energy generating capacity is now at around 6700 megawatts, up from 2550 in 2000. By contrast, the total amount of electricity that could be potentially generated from wind in the U.S. has been estimated at 10,777 billion kWh annually—about three times the electricity generated in the U.S. today.

The American wind energy industry is poised for rapid growth, with many new projects coming online. These new wind farms demonstrate how wind energy can help meet the growing need for clean, affordable, reliable power in the west and other parts of the U.S. For more data about wind power, see www.awea.org


The wind blows to the south, and goes around to the north; round and round goes the wind, and on its circuits the wind returns. —Ecclesiastes 1:6

Current sources of electricity in the U.S.: 
coal, 52%; nuclear, 20%; natural gas, 16%;  hydropower, 7%; and oil, 3%.

We have a great many informative links on our web page at www.oasismontana.com/links.html —regarding solar hot water, energy efficiency, financing, lighting, healthy homebuilding and other data.

Greetings from our solar powered office!

In the event of a lengthy power outage, what are your critical loads?

With the presence of winter storms, hurricanes, tornados and aging grid infrastructure as part of daily life, many people are rethinking how reliable utility power really is, and we are getting more calls for back-up power for certain loads. Some of our customers just need to have power for charging their cell phones, Kindles, tablets or similar devices (and a couple of lights or a small TV for an hour or so); a small system for them might entail the following components:

System #1, small system: One ~300W solar module, 300W sine wave inverter, charge controller, 12V 55AH AGM battery, combiner enclosure with fuse, flush roof rack, panel output cable; $1449
For additional information on smallish, RV-type systems, visit http://www.oasismontana.com/RV_systems.html.

Other folks are concerned about losing their food if the grid goes down, so they’ll want to power their refrigerator and perhaps a freezer too. If your appliances are of more recent vintage, backing them up will cost much less than if they are older, less efficient models. An efficient refrigerator shouldn’t use much more than a kilowatthour a day, and a freezer might be in the ~1.5KWH range (but contact the manufacturer to be certain). A system to power those loads, plus a couple of lights, might entail these components:

System #2, medium system: (MS2812 Magnum inverter, 6 ~300W solar modules, 6X top of pole mount, Classic 200 MPPT charge controller, 4 L16 type batteries + cabling, battery monitor, interconnects, combiners and disconnects; $8700

If you don’t have city water, a common concern is powering your well pump. One can live without a lot of things but water is not one of them! And many deep well pumps are 240VAC; if you needed a backup power system to run your ½ HP 240VAC pump, say, one hour a day, plus extra power for a fridge and small loads, you might be looking at a system of this size:

System #3, large system: (Radian GS4048 – loaded, on a pre-wired power center that includes the charge controller, MATE3 system monitor, disconnects, etc., 12 – ~300W solar modules, 16 – L16 type batteries, pole mount, battery cabling = $14750

Costs do not include freight, installation, concrete footer for pole mounts, ground rod & clamp, and miscellaneous electrical widgets or wire runs.


Some people think solar modules are ugly – but I think they’re beautiful…and how wonderful it is to get electricity from sunlight!
And, you can enjoy saving money while saving the planet.


Are you looking at a stock watering project this year? Or you want power for a pump if the utility fails? Or perhaps you have a pond to fill, or fruit trees that need irrigating? A remote cabin? Contact us for all your remote water pumping needs; visit www.PVsolarpumps.com for more information.

If your only concern if the power goes out is water and you have a, say, 1.5 HP 240VAC pump, we can now run many of those pumps array direct whenever the sun is shining. So if you need water for irrigation or stock, this new PicoCell system might be just what you need. The PicoCell, from SunTech Drives, is now part of our line of quality solar products, and we look forward to the next generation of their solar evolution as the newer and more robust water pump solutions come on board. Being powerless doesn’t mean being waterless any more! Depending on your water pump make and model, we may have a solution for those times when the power is gone but the need for water exists and the sun is shining. Three-phase water pumps and motors under 2HP manufactured by Berkley, Franklin, Flint, Goulds, Grundfos, Myers and Wailing are all great candidates for using the new PicoCell from SunTech Drive to run your water pump while the sun is shining and conventional power is out. Single phase pumps up to 1HP from these same manufacturers, including Sta-Rite are able to operate effectively also. Call for more information or to see if your pump will work with a PicoCell. 406-777-4321

Cows LOVE solar water pumping!


We offer the Grundfos, SunRotor, Dankoff and Lorentz pump line, from submersible to surface pumps. And we can power your 240VAC pump too! 406-777-4321 for tech support on pump systems.


TAX SEASON is nearly upon us! If you had a solar power system installed and running by 31st December, 2017, you are eligible for a 30% tax credit of the cost of your solar module installation, less any state incentives or rebates.

MNChinook 200 Wind Turbine Now Officially Available http://files.constantcontact.com/aaa32e00401/5cc9c46b-fd24-4c58-8538-64e359dee783.jpg
The Chinook 200 is now new and improved, a direct-drive micro-turbine designed for use in 12, 24 or 48 volt DC battery charging applications. Its attractive low-profile design, exceptional performance in low winds and low rotor acoustics, make this turbine the ideal choice for almost any application. It’s also very quiet, and mounts on a 1.5” Schedule 40 steel pipe.

The Chinook 200 can also work hand-in-hand with PV panels to ensure that power is being generated in all weather conditions; they can be charging the same battery bank, and are also suitable for marine use. The MidNite Chinook Diversion Load (CDL) is an integrated solution designed to prevent 12, 24 or 48 volt batteries from overcharging and is included with the Chinook 200. Compact and easy to install, the CDL incorporates a 300 Watt resistive heating element and controller board in a powder coated steel enclosure. $995 plus shipping includes its dump load controller. The output voltage is not field selectable and must be ordered for either 12V, 24V or 48V battery charging. Designed in Montana and still made in the USA, if you have good average wind speeds (10-12 mph+) you will find this to be an excellent addition to your battery charging scheme.
