• Solutions for an autonomous power supply

    Phocos AG is among the world's leading manufacturers of solar-powered charge controllers and components for autonomous power supply. Energy-saving appliances such as lamps, refrigeration/freezing appliances and TV monitors supplement the product spectrum. The products developed and produced by Phocos enable the eco-friendly and efficient use of solar energy.

  • The core: mains-independent photovoltaic installations

    In principle, a PV system consists of four parts: the solar modules, the solar-powered charge controller, the battery and the electrical loads. Phocos solar-powered charge controllers comprise the core of such systems. Their function is to safeguard the battery against overcharging and against discharge in excess of a given limit value. In addition, Phocos charge controllers increase the efficiency of the system as a whole.

  • Origin in research

    The origin of Phocos lies in research: in the mid-1980s, engineers at Ulm University of Applied Sciences developed new technologies for charge controllers. Toward the end of the year 2000, some of these researchers founded the company Phocos AG. To this day, Phocos maintains a close co-operation with Ulm University of Applied Sciences in the field of autonomous power supply.

  • Orientation towards market demand

    The founders of Phocos AG set their sights particularly on "off-grid" applications: solar-power-based isolated applications with no connection to the central power mains. Especially in the rural regions of developing and emerging economies, the demand for such autonomous systems remains high. Yet the demand for mains-independent solar-power system is also continuously on the rise in the world's industrialized nations. The reasons behind this trend lie in lower installation and operation costs, as well as in mobile application options. This means that Phocos solar-powered charge controllers are used, for instance, in street lights or mobile homes and boats to provide an energy supply. Other areas of application in ever-higher demand include telecommunications and heavy-industry operations.

  • On-site production

    Phocos contributes to making eco-friendly energy available – even in the most remote regions of the world. To enable the supply of the necessary technology at market-driven prices, Phocos manufactures its products in the vicinity of the major business markets within China, India and Bolivia. The corporate headquarters and the engineering division are both based in Ulm, Germany. Via its 12 holding companies and service offices, Phocos enjoys a worldwide presence.
