Hymer Cooperation

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.

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.

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.

Businesses are mainly souvenir shops, electronic products, tailoring, financial and printing services. With remote monitoring functions, all important system information and energy consumption can be read. PAYG makes it possible for
customers to book their current
contracts in advance on there mobile phone or in the service center. The prices for the shop owner are well below the costs of the old diesel generators.
