Electrifying Mountain Huts

Norway is known for its natural wonders such as fjords, mountains and northern lights. If you go on a tour in the nature you often spend the night in one of the numerous huts and experience the beautiful nature far away from civilization. But especially for the hut owners this also means away from any electricity connection. After the Grimsdalshytta built a new winter drying room, the owner decided on a solar system that has to work in winter. Therefore, they decided to install our HS500 hybrid storage system. Due to the very short sun duration the solar panels were installed very steeply and with large surface and by a special cold insulation for the HS system, it resists also in the winter problem-free. Local electricians have been trained in the technology so that maintenance and repairs can be carried out quickly.

From now on the new drying room will be supplied with light in winter and guests can recharge their mobile phones and cameras to be prepared for the breath taking nature.

Making the world and people’s lives a bit better is what drives us and what we do every day with our projects. Get to know many more of our projects in countries all over the world with different climates, cultures and people.

Katate Health Center

The existing health station of Kanungu was in a very poor condition. Simple birth complications, fractures, and infectious diseases often led to death. A state-private initiative turned it into a fully functioning
hospital. Thanks to our energy storage systems, all necessary loads can be handled, especially for operations like autoclave, vacuum pumps, electrosurgical
cutters, anesthesia equipment, and surgical lights. For secure energy supply, BOS energy systems combine electricity
from solar energy, the main power grid, and a diesel generator. This project shows that even in remote areas a very
high medical level is possible.

Sailboat Windzang

The passionate sailor Peter Reinmann extended his lead acid energy storage of his 9.30 meter long sailing catamaran with two BOS LiFePO4 Lithium modules. Peter is thus able to operate all the on-board electronics such as navigation, radio, light, refrigerator and gas heating. Because there was no room under the bench seat for a larger supply battery, a LE300 hybrid system was the perfect solution without loosing too much space. Now he is able to enjoy longer trips on the water without returning for recharge. A freedom that he no longer wants to miss.

Electrifying Health Posts Zambia

Health care in rural African regions is a
big challenge. The focus in this project
was on clinics which are off-grid,
very remote and take care of many communities.
People depend on the health
posts and often have to walk many miles
to get medical help. No power affected
Lukolongo as well as Chisakila, Mbimbe
and Munyeo in Zambia. With BOS Hybrid
Systems all four health posts and the
doctor housing get power for lights, fans
and the ability to store medicines and
vaccinations in a refrigerator.
With electrification, a first important step
was set for quality medical care and to
support the communities.

Sarvantara Village

INDIA | Together with the German Energy Agency (dena) and the German Federal Ministry for Economic Affairs and Energy (BMWi), a renewable energy solution project was initiated in 2017 in India in order to electrify a village with limited access to the existing grid.
The selected village in Uttar Pradesh has approximately 100 households. Thanks to the intelligent DC mini grid and renewable electricity produced using photovoltaic modules, the households’ basic electrification needs could be covered and the village’s water supply improved with solar pump systems. At the same time, investment costs stayed low, as highly efficient DC loads (such as LED lamps and low power consumption fans) require smaller solar systems.
With the support of our local partner Oorja to operate the grid service, training and maintenance work are guaranteed. The entire system is designed to deliver affordable, reliable and sustainable electricity for ten years.

This project is part of the worldwide dena Renewable Energy Solutions Programme coordinated by Deutsche Energie-Agentur (dena) – the German Energy Agency – and co-financed by the German Federal Ministry for Economic Affairs and Energy (BMWi) within the German Energy Solutions Initiative.
