The UN Climate Conference in
Copenhagen defined CO2 emissions
reduction as having a global value
for the international community.
The reduction of this greenhouse
gas should be a global goal.

T h e p r o du c t i o n
In 1896, gold miners at the Canadian Klondike river panned for gold
with a shovel, hoe, and sieve.
Changers credits, the gold of the 21st century, are generated with the
solar panel Maroshi and the intelligent solar battery Kalhuohfummi.
Your Kalhuohfummi measures your CO2 savings and reports these
contributions to the Community.
The production of one watt-hour of renewable energy is equivalent
to half a gram of CO2 savings, on average, as specified by the
International Energy Agency. This is the basis of our measurement
of individual and community savings.
“The only
by the sun”
The story behind it all
Kalhuohfummi and Maroshi
Make a decision,
produce your own energy
and change the world.
The history of Kalhuohfummi and Maroshi begins in the 16th
century with an unequal struggle for freedom and independence.
At the time, the greatest threat to the Maldives was Portuguese
conquest. The Maldivian people built a warship called Kalhuohfummi for their defense, which proved vital to the success of their
guerilla fighting. The ship’s sails were made on Maroshi, an island
where the warship was also loaded with drinking water for supplying the fighters.
Today, the greatest danger to the Maldives is the steadily rising water level caused by climate change. And again it is Kalhuohfummi,
the intelligent solar battery, which is docked to the island Maroshi,
the solar panel, that gets loaded with energy and supplies the
warrior of light in the fight against climate change and destruction
of our environment.
Technical Specifications
The idea behind Changers is to motivate as many people as possible to produce their own energy and thereby make a contribution
towards the prevention of climate change. We want to raise awareness of the impact that our behaviour has on our environment and
help make this world a better place.

4 Initialization of the battery KALHUOHFUMMI
5 How the Solar Panel MAROSHI Functions
Your battery works like a small computer. It does much more than just store
energy and charge your devices. Connect the Kalhuohfummi with your computer using the provided USB data cable to take advantage of the battery’s
many features.
The solar panel Maroshi reaches its maximum capacity when unfiltered
sunlight shines directly on it. The panel is weatherproof and can be used
outside throughout the year, though it is best installed somewhere sheltered
from direct rain.
Activate the Changers software. Then press the battery’s round button and
wait for the software to recognize the battery. This opens a dialog box to
login and connect your battery with your personal profile.
If you choose to mount the panel on the inside of a window, make sure
the window is not tinted and does not have a UV filter to ensure the panel
works as efficiently as possible.
Log-In Data: Enter the e-mail and password you used to register a profile
directly on Changers.com.

Complete the initialization and personalization of your battery according to
the instructions. Now you are ready to generate and track your own energy.
The solar panel has a durable 2 meter long cable with a DC plug that should
be plugged into the “Sun” charging socket of the solar battery. Check that
the plug is firmly secured and deep in the socket to ensure solid contact
between the panel and battery.

7 Installation
The solar panel Maroshi is flexible but
not unbreakable. Please take care of
your solar panel.
8 Generate energy
Status LED for data transmission and
error messages
The solar battery has a control button and an LED display. If your solar panel
is illuminated directly by the sun, the charging process of the battery will
begin immediately and the LED display will flash.
The flashing of the LED display shows you not only whether the battery
is charging, but also indicates the amount of incoming solar power. At an
input of 10 watts, the LED light is solid unblinking and with an input of 3
watts, the display blinks 3 times per second, etc.
Depending on the angle at which the sun’s rays hit the solar panel, the
flashing frequency of the LED display will change. Once the battery is fully
charged, the charging stops automatically. Your battery has now stored the
energy of about 16 watt-hours.

You can check to what extent the battery is charged by pressing the round
control button. The LED display shows you the charge level of the battery for
5 seconds. If the Kalhuohfummi is completely discharged, no LEDs light up.
To efficiently store the energy inside the battery when not in use, the device
switches itself off. It is immediately restored by pressing the round button.

8 adapters for various
small devices
The battery Kalhuohfummi charges nearly all small mobile devices that can
take in 5 Volts via USB power. To charge a mobile device, use the supplied
USB to micro USB cable or the original charging cable that came with your
device. All Apple products should be charged with their original cables.
For full compatibility, a USB to DC Jack cable is included with 8 adapters:
mini USB, LG KG80, Nokia 2mm, Sony Ericsson, Samsung D800, Sony PSP,
Nintendo DS/GB, and Nintendo DS lite.
Plug the charger cable into the battery’s “Power Out” jack. The charging
process begins and the LED should flash. The flashing LED indicates that the
device is being charged, even though the device may report the opposite.
