Dynamisches MPPT für Wilo-Actun OPTI

Dynamic MPPT

If there is a change in the exposure of the solar modules, the maximum performance point (MPP), current and performance are offset in relation to the voltage. The MPPT algorithm identifies the ideal ratio between electric current and voltage to consequently dynamically actuate MPP. As a result, the available exposure to sunlight is optimally converted into electrical power to maximise the water supply.
