Hymer Cooperation

Bad Waldsee, Germany

BOS Lithium Extension Batteries are the main component of the new
innovative hybrid storage battery for Hymer caravans.

HYMER GmbH & Co. KG is one of the largest manufacturer of motorhomes and caravans in Europe. The HYMER-smart-battery-system will offer more freedom of energy and independence in travel. Thanks to the significant higher self-sufficiency and integrated battery heating, campers can stay many days longer at a beautiful place, even in winter. The system is installed as standard in selected models and can be retrofitted in all motorhomes and caravans.

Solar Energy for Honduras

Reliable power, functioning energy infrastructure and independence from diesel generators. This is what many Hondurans want and need to keep their businesses, institutions, and homes running. With our solar storage systems, we provide a solution that meets their needs. Together with our local partner Innovative Business Solutions (IBS) and as a part of the dena Renewable Energy Solutions Programme, we have chosen five pilot locations in the country to demonstrate our technology. Three hotels and two municipalities now run with a BOS solar storage system. The results: Lower electricity bills, uninterrupted power supply and cleaner air.

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.

Sabon Gari Market

Sabon Gari market has been often in the headlines because of big fires, that destroyed large parts of the market. The root cause was the usage of many diesel generators. The Nigerian government and various companies have jointly come up with a solution. Equipped with the BOS Systems all 12,000 shops receive green, stable and affordable power for lamps, fans, television, computer and mobile phones. More markets have followed.
