Maximum Light Detection principle is based on the most accurate, fastest and most energy-saving tracking of the solar module toward the maximum energy point. That function is the responsibility of the patented control module, the MLD sensor. The control module continually measures intensity and angle of the incoming light and moves the solar module installation into the most advantageous position. The module not only takes the solar irradiation into account, but also, for example, light that is reflected off snow, water or light-colored rock, or diffuse solar irradiation that penetrates the clouds – and does so individually for each system. What is important here: only those movements that will result in a direct yield increase are carried out.
SIMPLY BRILLIANT AND BRILLIANTLY SIMPLE
Two sensor cells in the MLD sensor provide reference values that are evaluated by a logic module to track the module surface over the course of the day. A third sensor resets the system each morning. Depending on the irradiation, a differential amplifier prompts a transition from the logarithmic characteristic curve created by strong radiation to the linear characteristic curve created by diffused light. In this dependent relationship, the logic module has a much higher value in the linear characteristic curve than in the logarithmic one. This optimizes the accuracy of any readjustments made when brightness is decreasing.
The drive is directly controlled by an electronic circuit (extremely low switching resistances) micro processor built into the MLD sensor. A current limiter prevents the motor and the DEGER structure from overloading. In the event of overload (due to a frozen or blocked drive for example), the motor is switched off. As soon as the drive is running freely again, the motor is automatically reset.
ECONOMICAL: THE ENERGY CONVERTER
Wide voltage ranges of solar modules, battery systems, and the network are made available to the MLD sensor in the energy converter. This makes it possible to supply power to the control and drive systems through a direct connection to the solar module – with less than a Watt of power.
