Solar Pumping Systems are nowadays very much common. SPV modules are used to run pumps to get water. These systems come in two types one with Submersible pumps one with surface pumps. These pumps run with AC power. SPV modules provide us DC. To integrate them together one VFD based pump controller is used.
Variable Frequency Drive: A variable-frequency drive (VFD) is a type of motor drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and, depending on the topology, to control associated voltage or current variation.
