The Photovoltaic generator (PV – generator) is the total arrangement of modules and branches. Solar cells are the smallest units of a photovoltaic installation and convert light into current (photoelectric effect). The individual solar cells are connected together in a module (in series connection).

In order to achieve a higher system voltage, modules are connected in Series, called a string. PV strings of a Solar PV array are electrically connected to array junction box with protection devices.

Grid-connected Inverter is an integrated system consisting of a solar charge controller and inverter which converts the direct current (DC) generated by the PV arrays to Alternating Current (AC) which is fed to the LT panel.
