PV Array Requirements
3.2.1.
Serial connection (string) of PV modules
As the core component of the solar system, the controller could be suitable for various types of PV
modules and maximize converting solar energy into electrical energy. According to the open-circuit
voltage (VOC) and the maximum power point voltage (VMpp) of the MPPT controller, the series
number of different types of PV modules can be calculated. The below table is for reference only.
