Whether stationary or mobile power supply: We offer expert advice, planning and an individual intelligent product.

Designed for systems whose function must be ensured at all times:

A reliable independent energy supply is becoming increasingly important in many areas. Reliability is of the highest importance when it comes to the complete recording of characteristic data, the monitoring of sensitive measurement data or the storage of important information. New technologies offer unprecedented possibilities here.


Smart City


Cities and communities are becoming smarter and smarter. Whether it is the disposal of waste or the monitoring of parking lots - modern technologies offer a variety of possibilities to make urban and rural structures clean, environmentally friendly, effective and cost-effective. Very often, however, there are no connections to the power grid or the Internet. We offer specific solutions with self-sufficient power supply and secure communication technology.

Schematic simple application area QTARK, basic modular system:

The module supplies the consumer and the battery via the charge controller. If the energy of the module is not sufficient, it is taken from the battery.

Schematic of extended QTARK application range, extension:

The module supplies the sensors and possible consumers as well as the battery via the charge controller. If the energy of the module is not sufficient, it is taken from the battery.

The solutions, including the entire electronics, can be integrated in a single housing with very small dimensions.

Different sensor types offer complete monitoring and control.

The data is broken down and further processed according to your requirements.


QTARK Modular System

The system is designed in a special way that a service and maintenance free operation of 5 - 10 years can be achieved for low energy applications!
