Sailboat Windzang

Ijsselmeer, Netherlands

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.

Refugee tents with power

Uganda is the third-largest refugee-hosting country in Africa. Basic needs such as water, food, and electricity are hard to tackle in these camps. 70% of the refugees depend on organizations like the World Food Programme (WFP). To support the WFP, we equipped tents from Hallgruppen with our turnkey BOS solar storage solution. For the installation, we partnered up with the local electricity partner Aptech. Now WFP can store food and supplies safely and have access to reliable and clean energy. The remote monitoring system helps to control the energy and system performance from anywhere in the world. Therefore Aptrech can monitor the system from everywhere, which makes servicing easy and efficient.

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.

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.

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.
