The minimum string size, then, is 15 modules. The maximum string size is the maximum number of PV modules that can be connected in series and maintain a voltage below the maximum allowed input voltage of the inverter. The Module Voc_max is calculated using the coldest temperature when the modules produce the highest expected 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. However, several high-voltage models are available which operate up to 600V.
Most modern string inverters have a multiple power point tracking (MPPT) that operates within a specific voltage range. Checking the minimum voltage does two things: Checking the maximum voltage does two things: Checking the maximum Isc or maximum current does one thing: Checking the maximum connected power is below the inverter’s max.
Once you find this voltage, find the minimum start-up or MPPT voltage for the inverter and calculate the minimum string length. (Inverter Min Voltage) / ( V low) = Minimum String Length Ensure that the highest voltage during the lowest temperature is within the inverter’s max and near the upper MPPT range.
