The goal of the diploma thesis was to develop a system, which controls energy
generated with solar modules. The main job of the controller is measuring
voltage and current of generated electrical energy and at the same time con-
trol heater of sanitation water. As an addition a back-end server system
was made, which can potentially receive data about generated voltage and
current from many such controllers. When designing the electric circuit we
took care that the controlled line is galvanically isolated from the electronics
which are responsible for logic. After we produced the circuits we started to
develop in web based environment Arm Mbed where we used Mbed OS oper-
ating system and developed the software which works on development board
STM32F746NG-DISCO and connects with our circuit. After we finished
the development we connected the controller into final work environment,
collected some measurements and displayed them in a graph.
