The history of Phocos can be tracked back to the mid-eighties, when a group of engineers at the University of Applied Sciences in Ulm started to develop new technologies for solar charge regulators. Since 1991 the developed technologies are implemented in series products.

In late 2000 the team of engineers joined with further shareholders (among them the Centre for Solar Energy and Hydrogen Research in Ulm and Stuttgart) and created the Phocos AG.

Since then Phocos develops, produces and distributes innovative products for autonomous electricity supply systems.

Phocos now is a leading player in the world of renewable energy in grid-independent power supplies; it provides a wide range of high-technology components for off-grid power supply systems based on renewable energy. They supply low-cost products for rural electrification and highly sophisticated, customized industrial solutions.

Phocos concentrates its product development on components in stand-alone Photovoltaic systems, but its products around the improvement of the energy storage can be used in hybrid systems as well. Goal is to increase efficiency and reliability and to lower the cost through intelligent production, storage and consumption of energy.

The technology mission of Phocos is simple. Solar systems for off-grid electrification highly depend on the reliability of the storage battery. Improving battery management and appliance therefore is the long-term key issue. Phocos can rely on the experience of its engineers and on a number of co-operations. The enterprise is connected with the University of Applied Sciences I Ulm by a tradition of many years.

Phocos co-operates with the Centre for Solar Energy and Hydrogen Research particularly in the field of fuel-cell technology, which is considered as an essential component for future electricity supply systems. In the year 2001 a photovoltaic fuel-cell hybrid demonstration system was presented for the first time.

Phocos products are used in different applications, like private recreational systems, rural electrification, industrial power supplies, Telecom, Traffic control and Lightening.
