SG200 solar pump inverter MPPT 0.75kw-4kw 220V pump VFD
SG200 Solar Pump inverter
The SG200 series solar pump inverter is a low voltage AC drive of 075KW to 4kw 220V above rating designed to operate with energy drawn from solar panel or photovoltaic cells (PV). The inverter is customized to operate in dual supply mode, so the grid connected supply is used in the absence of energy from PV cells. This drive functions with the latest in technology maximum power point tracking (MPPT) algorithm to derive maximum power from the PV cells at any instant.
SG200 solar pump inverter features
SG320 series solar pump inverter compatible with dual supply mode
The solar pump inverter operates in dual supply mode either with a three phase input supply from the grid or with DC input supply from PV cells.
A four-pole changeover switch enables switching between the two supply modes. At a given time only one power supply (PV cell or grid) can be connected to the drive.
How does it work ?
An arrays of solar panels generates the power and voltage required
for the SG300/3200 Solar inverter 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.
Benefits
• Pumping of water in for irrigation for drinking water supply in
off grid areas, easy installation.
• Farmer can cultivate multiple crops through out the year in off
grid areas
• Farmer can save their time spent in collecting and transporting
water.
• Lower operation expense compared to diesel pumps
• Zero emission of green house gases.
• Reduced load on national grid.
