Strings konfigurieren

Jeder String hat spezifische Eigenschaften, wie z. B. die Abweichung vom Süden (Azimut) oder der Neigungswinkel des Daches. Die Konfiguration der Strings ist ein grundlegender Pfeiler für die korrekte Errechnung der PV-Prognose und damit eine wichtige Voraussetzung für die Verbraucherplanung sowie die Optimierung von Eigenverbrauch und Autarkiequote.

Photonik | String Voltage Calculator

As the string voltages changes, the MPPT will continuously adjust and track the optimum string voltage. The MPPT operating voltage range for most string inverters is between 80V and 600V, depending on the inverter make and model. The voltage range for Solar MPPT charge controllers is generally much lower and varies from 24V up to 250V.
