Variable SELV-input voltage for batterie and solar cell operation

The autarkic energy supply solutions conquer more and more places of application. Especially in the remote areas without public power supply or for mobile installations, photovoltaic autarckic solutions with safety extra-low voltage (SELV) are often used. For exactly such stand-alone solutions, we have developed the SONNA luminaire with the variable SELV input voltage (from 9 to 55 volts). Therefore, the luminaire can be operated directly from a solar cell or from a rechargeable battery. In doing so, it provides constant light.

The SONNA luminaire has appliance classes III and IP65 protection. It is also vandal-proof due to its compact and robust housing. The high efficiency of the installed LEDs guarantee a high luminous efficiency with the best light quality at a minimum energy consumption. This combination of features guarantees you a long life-time and reliable operation of up to 20 years.
