Mission Energy
Solar VFD Drives
VFD Drive or Adjustable Speed Drives are used in any application in which there is mechanical equipment powered by motors; the drives provide extremely precise electrical motor control, so that motor speeds can be ramped up and down, and maintained, at speeds required; doing so utilises only the energy required, rather than having a motor run at constant speed and utilising an excess of energy.Since motors consume a majority of the energy produced, the control of motors, based on demands of loads, increases in importance, as energy supplies become ever more strained. Additionally, end users of motors can realise 25 - 70% energy savings via use of motor controllers.Despite these benefits, the majority of motors continue to be operated without drives.
An array of solar panels generates the power and voltage required for the ATV312 Solar to drive the motor. The solar drive converts the DC voltage input to a 3-phase AC output with variable voltage and frequency.The MPPT algorithm of solar drive extracts maximum power available from the solar panels during the day and operates the motor at variable speed based on the power input to the drive. The frequency range in which the drive operates depends upon the motor speed, hydraulic system and the power available from the solar panel. As the sunshine varies during the day, power input to the drive varies and the Solar drive generates variable V/F ratio thus controlling the speed of the motor, which in turn regulates the pump impeller speed. Water Level Sensor is used only when the water is pumped to overhead tank.
SRB provide VFD Drives of high efficient with reputed international brands.
