Differ's solutions reach across the distributed electricity value chain. We are continuously looking for interesting technology and implementation ideas that could make a difference, reduce the carbon footprint and create profits in small- and medium scale new electricity markets.

Our focus is on well-tested and established technologies applied in areas such as electricity generation using renewable energy sources, energy efficiency and waste management.

We work together with our portfolio company, and we develop own concepts. In a world of small renewable energy, scalability is important for lowering end-user costs, increasing profitability and overall social and environmental benefits. We do not invest in single projects unless they are instrumental for other solutions in our portfolio.



BOS AG aims at becoming the leading company in decentralised energy supply with a focus on Li-Pb (lithium-lead) hybrid charging technology that supports intelligent load management.

The key markets are located in rural and semi-urban areas of the world with insufficient access to modern energy services, as well as market segments in industrialized countries that require decentralized power supply (e.g. street infrastructure, offshore, mobile entities, holiday homes and other remote locations). Storage costs per kWh with BOS' proprietary hybrid battery management systems are up to eight times cheaper than with other storage technologies. Combined with intelligent load management, the energy service for the customer is more than ten times more attractive.

BOS delivers energy storage systems, DC grid technology, lithium extension batteries in addition to DC hybrid storage systems, with customers in Europe, Africa, India and South America.



VITALITE Zambia was established 2014 by Differ and local partners in Zambia. It sells appropriate, affordable and acceptable household energy products to low-income customers while giving the best possible service.

Vitalite is a successful player in the Zambian market for solar home systems, with more than 20.000 SHS sold over the past few years. The company is hardware agnostic, and is integrated with PayGo software to operate a cashless operation. Over the past year, Vitalite has also included agricultural products in their portfolio to diversify from solar home systems alone.

Finally, Vitalite Zambia distributed and sold Prime cookstoves, as well as wood fuel sourced from existing sources of sustainably harvested biomass. The company's goal is to deliver clean energy solutions at prices affordable for peri-urban and urban poor without subsidies.



High quality pico system producer
