GREETINGS FROM OUR SOLAR POWERED OFFICE!
This past winter was relatively mild in our western
Montana valley; it was strange (but fine!) to have so many mornings
without scraping the windshield or thawing frozen water buckets. But the
snowpack is good up in the mountains, so we are hoping for a summer
without too many forest fires.
In this issue of our newsletter, our main focus is
the need for backup power systems. Power failures are becoming
more frequent and of greater duration, but running your necessary loads
doesn't need to be terribly complex.
Some folks who have a grid-tie solar power system with no batteries
realize that they are without electricity if the
utility goes down. But now there are battery-based options available to
power essential loads in the face of
unreliable utility power.
BACKUP BATTERY POWER SYSTEMS
Backup power doesn’t have to be complicated.
Here’s an example of an independent power system that will run your
(efficient) refrigerator, computer or TV, and a few lights (all 115VAC
loads). The basic components:
- 4—185W Solar Modules / Combiner Enclosure and
Breakers / Surge Protection
- A-frame Roof or Ground Mount / Samlex 2Kw, 12V Sine
Wave Inverter / AC Subpanel/Safety Fuses
- Charge Controller / Eight 6V, 250aH Batteries /
Battery Monitor & Cables
This system totals out right around $4999 before freight,
installation, wire runs, and miscellaneous electrical widgets. This system
will provide approximately ~2200 watt-hours per day for four hours of full
sunlight. You will get more in the summer (and less in the winter),
depending on your location and amount of sun received. The batteries will
provide three days of back-up power at the usage rate of ~2000 watt-hours
If you think the loads you want to power would exceed
2000 watts (continuous draw), you can go with a larger inverter; we have
found those manufactured by Magnum Energy to be very reliable, as well as
offering 240VAC capacity.
Examples of different types of roof/ground
mounts. Many people prefer pole mounts (far right), as they are easy to
seasonally adjust for a better angle to catch the sun’s
The batteries specified in the example systems, above,
are flooded lead acid; they are still the best deal but will require
maintenance, and they need to be in a vented battery enclosure. A plywood
box with the top vented with a PVC pipe is quite adequate (vented to the
outside of your garage, shop, or basement), but if you are unable to
maintain your batteries you may need to consider absorbed glass mat (AGM)
or gel-cell batteries. They are more costly and have a shorter cycle life
but require little (virtually no) maintenance except for regular charging.
The correct charge controller for your system depends on the
features you desire and the amperage coming off your solar array; if you
plan to add to your system, it’s a good idea to get the size controller
you need at the onset, saving you money in the long run.

Inverters take the DC power from your batteries to
run your regular AC loads; they are generally sized according to two
factors, the continuous amount of power needed and the peak loads
(total watts of the maximum amount of electricity running at one
time). You’ve probably seen the smaller inverters in the 50W to 200W
range, with a DC plug that can run off the 12V supply in your car.
The bigger models can handle whatever loads you need to power, as
long as they do not exceed their current rating.

Energy inverters. Right: Outback Power inverter.
Proper sizing of your inverter is very important, as it's a costly
component to upgrade--so be sure to get the correct size at the
The load sizing is critical in determining which inverter
is best for your project. If it is undersized, it won’t handle the loads
you want to run; and if it is oversized, you will pay more than is
necessary. The Samlex are fine quality, low-cost, smaller inverters with
excellent sine-wave AC power output, but they do not have a built-in
battery charger as do Magnum and Outback. If you plan to integrate a fuel
generator into your back-up system, you will either need a separate
battery charger or an inverter with one that is built in. We have

POWER OUTAGE SOLUTIONS
Are you ready for your next power outage? With the advent
of superstorms such as Hurricane Sandy, floods, unpredictable tornadoes,
or simply because of aging utility infrastructure, Americans are dealing
more and more with undependable utility (grid) power. We at Oasis Montana
have been designing backup power systems for whatever loads you need to
run; we can make these systems seamless so you do not know the power’s
even gone out, or, you can plug in your specific loads as needed at the
time of a power outage. Recent power outages show people the tremendous
value of backup systems, and there are many different solutions to utilize
inverters for backup capability. Connecting backup loads can be very
simple or complex. And, the amount of time provided for backup power
depends on the loads you want to run and your battery
During a power outage, an auto-transfer
switch in the inverter opens the grid-interconnect, which isolates
the building from the utility to prevent any back-feeding into the
local power lines. Then the inverter draws from the batteries to
provide AC power to the subpanel. If you are starting from scratch,
a DC coupled system is likely to be the most cost-effective and
reliable configuration to use.
The diagram at left is an example of a
D- coupled PV system; the solar (PV) array’s power goes through the
charge controller to charge the battery bank. When the batteries are
fully charged, power is fed back through the inverter for use. The
inverter output is connected to the backup (i.e. critical load)
subpanel, as well as grid-intertied to the main electrical panel.
Under normal conditions, it functions like any net-metered
In an “AC coupled system (right), a
batteryless, grid-tie inverter is connected to the solar array,
while a battery-based inverter is used to power loads from the
battery bank in the event of a utility outage. In this scenario, the
AC output of the grid-tie inverter is connected to the backup
(critical load) subpanel rather than the building main electrical
The backup subpanel is also connected to the AC
output of the battery inverter; the AC input of the battery inverter
is then connected to the main panel as in a DC-coupled
Under normal conditions, the batteryless grid-tie
inverter is passed through the battery-based inverter’s built-in
transfer switch to the main panel and utility inertia, without loss
Likewise, grid power can pass the other direction when
needed to power the loads in the backup subpanel. During a power outage,
the battery inverter’s transfer switch isolates itself from the utility
connection and provides AC power to the backup subpanel, drawing energy
from the battery bank. The batteryless grid-tie inverter will shut down at
the start of a blackout, but will turn back on (after a mandatory 5-minute
waiting period) when AC power from the battery inverter is detected,
supplying AC power to the backup subpanel. If enough power is available it
will be used by the battery inverter to charge the batteries. Note that
once the battery bank is fully charged and the loads are served, the
batteryless grid-tie inverter will need to be throttled back, diverted, or
shut down in order to prevent damage to the batteries, so you may need a
diversion regulator (or ‘dump load’) on the battery bank.
AC-coupled system offers a few advantages compared to the traditional
DC-coupled system. The batteryless grid-tie inverter can use the higher
voltage from the solar array, reducing the required wire size, and is
generally more efficient than a battery-based inverter. Additionally, if a
direct grid-tie system is already installed and battery backup is added
later, it is often more convenient and cost-effective to leave the
existing system in place. A disadvantage, though, is that AC-coupled
systems are typically much more expensive and complex to design, and only
certain inverters can be used in such systems. But, the battery-based
inverter can, with this type of system, be added to an existing grid-tie
system to provide necessary backup power in the event of a power outage,
resulting in money savings on your utility bill when the grid is up, and
to run whatever you need to when the power goes out.
the SMA Sunny Island is the only equipment specifically made to be
AC-coupled (with SMA Sunny Boy grid-tie inverters) and is fully factory
supported. With the exception of high-frequency inverters, such as Fronius
IG Plus and SMA SunnyBoy HF, most batteryless grid-tie inverters could be
made to work in an AC-coupled mode...but, most manufacturers cannot
provide adequate tech support, and some warranties will become void if the
inverter is AC coupled. OutBack Power and Magnum Energy make battery-based
inverters that can be used in an AC-coupled configuration.
of course, possible to have a battery backup system that is entirely
separate from a solar grid-tied system (like our example system on page
1). In parts of the world with frequent short outages, many people just
install a battery based inverter and battery bank without any PV
whatsoever. Very similar to a UPS (uninterrupted power system), the
battery is kept charged by the inverter from the utility AC power as long
as the power is on, and during a power outage will supply power from the
battery to AC loads. This type of system has no way of being recharged
during an outage, (unless you have a fuel generator or add photovoltaic
modules) so the amount of electricity provided cannot exceed your storage
capacity. Of course, adding PV power to this sort of system makes it just
like one of our basic remote power systems; simple since no grid-tie is
The common method of connecting backup loads is with a
subpanel that serves specific circuits. The backup subpanel (could be a
6-breaker Square D box) is typically installed next to the main panel so
that the circuit wiring can be easily transferred from the main panel to
the subpanel. These circuits are then automatically powered through the
backup system during a utility outage. Only complete circuits can be wired
this way, not individual appliances. Appliances can occasionally be moved
from other circuits onto a backed-up circuit or loads can be turned off of
backed-up circuits if they are not needed during an outage. And, you may
want to disconnect certain unnecessary large loads if they are on these
circuits, to prolong your battery backup. If it helpful for the end user,
unique styles or colors of receptacles can be installed on backed-up
circuits. It is possible to have a backup system power an entire home or
building if either the backup system is very large or the loads are
efficient and unusually low. This is not often done because it requires a
backup system large enough to power all loads in the house. Otherwise, the
loads running when the outage occurs may overload the inverter (or drain
your batteries quickly), defeating the backup system’s purpose.
For a grid-tied battery-based system, such as the one here in our
office, the sizing of the solar array is much the same as for a
non-battery grid-tie system. The limitations on the solar array are still:
space for installation, maximum offset of utility power, and budget. Often
a solar array sized for grid-tie will be more than large enough during a
power outage. For AC-coupled systems, the battery-based inverter typically
needs to be larger than the batteryless grid-tie inverter for best
results, since it must be able to power your continuous loads.
battery bank size is determined by the length of time and the size of the
loads to be run during an outage. Backup systems can be made to supply
power for minutes, hours, or days. If outages are brief or if a backup
generator is planned, the battery bank only needs to be large enough to
carry the loads for a few hours. Most often, a backup time of a half day
or multiple days is desired. If there is not much sun, a generator can be
run for a few hours per day to keep the battery bank charged. If the
system is to be capable of running indefinitely, it should be sized like a
true off-grid system.
As to batteries needed, the best bang for
the buck is still the flooded lead acid cells, but these require regular
maintenance and a battery box designed to safely outgas its fumes. If your
storage needs are not too great we would likely recommend AGM (absorbed
glass mat) batteries, which are non-spillable and require little
maintenance. (Diagrams and part of article source: Brad Bassett of AEE

Midnight Solar Battery Capacity
BATTERY CAPACITY METER from Midnite Solar:
These smart people have come up with a very simple and
cost-effective way of keeping track of your batteries' condition. If
you are serious about having back-up power, you NEED to know your
batteries’ state of charge. Not having a meter on your batteries is
a lot like driving a car with no gas gauge! The Battery Meter can be
used with all types of lead-acid batteries and will automatically
detect the voltage of the battery bank, but for the most accurate
readings you should set the meter for the type of battery being
monitored (gel, AGM, or flooded). You select the battery type by the
placement of a small jumper on the circuit board pins, and battery
voltage of 12V, 24V, 36V, and 48V is automatically selected.
These meters are intended for indoor use only and must be
protected from moisture and direct sun. Installation instructions
are clear and easy to follow. While there are other meters available
that offer more detailed information, at only $69 this one is hard
Do you have a
fuel generator for backup power? If you’ve had any
significant power outages lasting more than a few hours, you know
you need to keep a substantial fuel tank available. Many people,
whether for remote homes or for emergency backup, have found that
the addition of an inverter and battery bank will significantly
reduce the generator run time and save fuel. Most folks who have
generators only use a fraction of their output at any given time.
They'll be sucking down a half gallon an hour (or more) just to
power some lights, and maybe a microwave or fridge for a while,
leaving most of that capacity wasted. They'll go through 10-15
gallons a day to do very little work (there are some generators that
are better at throttling output to closely meet demand, but most
home generators out there don't). When you have a battery/inverter
system, you can fire up the generator, run it at full capacity for
an hour or two, then shut off the generator and run your AC loads as
needed since you are charging the battery bank via your inverter's
charger while your generator is running. You can make your fuel
resource last much longer. It is important that you size the
inverter so it will be able to handle the continuous power
requirements, as well as the starting surge, of any loads you wish
to run. In the average home this might be a water pump and a washing
machine, since those are two sizable loads that are apt to be
running at the same time.
We don’t sell generators but do
know how to specify the proper inverter for your project, as well as
what generator features to have (a 2-wire electric start is a real
good idea). We can make these systems turn-key enough that when your
battery voltage drops (from running your AC loads), your inverter
senses the voltage drop and turns on your generator; once the
batteries are ‘fat,' the inverter turns off your generator, saving
fuel. Questions? Give us a call at 406-777-4321 or toll-free

You too can have hot water on
demand—even with a standard electric water heater—and save on your
electric bill at the same time. One of the ways to
increase the efficiency of your water heater is to turn it off when
not in use. This option may not work for every household, but if
your family tends to take showers or do laundry on a more-or-less
regular basis, or the same time every day, you can really reduce the
electricity used by installing a general duty 30A safety switch.
These are readily available at your local hardware store; while it
is not difficult to install, you will probably want to hire a
professional to do it safely and properly.
My husband installed one here at our home/office, and we turn it on
15 to 30 minutes before we take our showers (or do laundry). After
showering, we turn it off again until the next time it’s needed. Why

Solar power system owners reap the
benefits of tax credits There
are still tax credits for these kinds of systems, (they’re not going to be
‘sequestered,’ thank goodness!), and your state or utility may also offer
additional incentives. The ITC (Investment Tax Credit) allows power system
owners to take a 30% federal tax credit of the qualifying costs of the
solar electric system. Now, the ITC can only be taken in the tax year the
system was placed in service; if you installed a system in 2012, you
should use IRS Form 3648 to take the tax credit for 2012. The ITC is not
refundable; if the 30% credit exceeds your federal tax liability, it can
be applied to next year’s taxes. The ITC is for system owners — if you are
leasing or financing your system, that system is not eligible for the ITC.
In most cases, any other state incentives or grants must be
subtracted from the system’s cost before calculating the tax credit. It’s
wise to speak to your accountant to determine if this applies to your
specific situation. And if you have a commercial system, there may be
additional federal tax benefits; some commercial solar owners can benefit
from 50% 'bonus' depreciation, which allows for the deduction of 50% of
the depreciable basis of a solar electric system in the first year of
operation. This benefit is available for commercial solar electric systems
placed in service in 2012 and 2013.
Many states also offer
incentives which can reduce your tax liability — and all of these make
solar power more affordable. You can find out what incentives are
available for you at http://www.dsireusa.org/ (a
state-by-state database that is updated regularly).
water pumping systems, at this time, you can only get the ITC on the
solar components, NOT on the pumping goods...
Stock watering and irrigation
systems are becoming more affordable and reliable.
But there are other grant possibilities for
solar pumping projects; Visit http://www.rurdev.usda.gov/BCP_Reap.html
for more information (or contact your local USDA or NRCS office for
information about their REAP programs). The drought that devastated
so much of the U.S. last year has spurred programs and financial
assistance for eligible landowners and agricultural producers for
irrigation, conservation and stock watering. NOTE that
Rural Energy for America Program (REAP) grant applications must be
submitted before May 31, 2013 (recently extended from April 30).
There are also wildlife oriented programs
through which the agency approves contracts to provide financial
assistance to help plan and implement conservation practices that
address natural resource concerns or opportunities to help save
energy, improve soil, water, plant, air, animal, and related
resources on agricultural lands and non-industrial private forest

is Cheaper Than Coal in New Mexico: Although new solar plants can't
yet compete on price with legacy coal plants, they are nearing the point
where their economics look better than those for new coal plants. That's
happening in New Mexico, where First Solar plans to sell solar electricity
from its new 50-megawatt Macho Springs project to El Paso Electric Co. at
5.79 cents per kilowatt-hour. That's less than half the 12.8 cents per kWh
that new coal plants typically charge. http://www.sustainablebusiness.com/index.cfm/go/news.display/id/24550.
Newman’s History of Oil: A little long but good-humored and very
climate change makes economic sense: The Hewlett Foundation recently
sponsored a study of the economic consequences of these policies over the
past three decades. It tells an amazing story. California now uses half as
much energy per capita as the nation as a whole, saving the average
household $1,000 each year, with total savings now more than $56 billion.
New York households have similarly benefited. Whereas per-capita
electricity use across the nation has increased 50 percent in the last 30
years, in New York it has risen only 15 percent, due to the state's focus
on energy conservation, saving billions of dollars. The bottom line here
is that saving energy is not only good for the environment, it also saves
people money. http://www.sfgate.com/opinion/openforum/article/Combating-global-warming-makes-economic-sense-2503537.php.

Plants Are Victims of Their Own Economics: Plans for more than 150 new
coal-fired power plants have been canceled since the mid-2000s, existing
plants have been closed, and in 2012, just one new coal-fired power plant
went online in the United States. http://news.sciencemag.org/sciencenow/2013/02/coal-plants-are-victims-of-their.html?ref=hp.
According to a detailed analysis of coal plant finances and economics by
the Institute for Energy Economics and Financial Analysis, coal is losing
its battle with other power sources mostly on its merits. Over the past 6
years coal's share of U.S. electrical generation has fallen from 50% to
38%. There are several reasons for coal’s decline. Over the past decade,
construction costs have risen sharply. In addition, since the mid-2000s,
the price of natural gas has plummeted. Coal is also struggling because
many power plants that burn it are aging to the point that more parts
break and they’re becoming expensive to maintain. Sixty percent of the
nation’s coal plants are more than 40 years old, and the median age of
coal plants retired in 2012 was 53 years.

Says Global Fossil Fuel Subsidies Dwarf Renewables Aid: The production
and consumption of fossil fuels add costs to society in the form of
detrimental impacts on resource availability, environment, and human
health. The U.S. National Academy of Sciences estimates that fossil fuel
subsidies cost the United States $120 billion in pollution and related
health care costs annually. But these costs aren’t reflected in fossil
fuel prices. http://www.worldwatch.org/fossil-fuel-and-renewable-energy-subsidies-rise-0.
