“NOW YOU CAN RUN YOUR EXISTING SUBMERSIBLE PUMP WITH SOLAR PV”


The recent technology developments and cost decline in solar PV has made it an attractive proposition to run your existing submersible pump on solar. There is no need of battery and it can directly connect the solar panels to the submersible pump input through a variable frequency drive (VFD). VFD is an electronic device equipped with  inverter and MPPT (Maximum Power Point Tracking). The variation of solar radiation is observed through frequency modulation and will run the submersible pump at constant torque for a wide range of sunlight from morning to evening. We have installed a similar system at the farm house of Mr. Ananth , about 70km from Hyderabad and the submersible pump has 5Hp motor which run continuously from morning to evening. The water is poured in overhead water tank which act as a storage device. We have installed 3.7Kw panel with single axis tracker which run the submersible pump with a constant output while varying the solar output. This is the fairly low cost solution to the farmers do not have grid electricity and have no other option to run their submersible pump. Installing solar PV at your land or Agriculture farm, it leaves completer dependency on  grid electricity. We believe that there is need to educate the people to adopt such low cost solution which can convert your existing pump as a solar pump.

FEATURES –

>This solar inverter with MPPT VF drive will give maximum torque even at minimum sunlight

> There is no need of any battery, directly connect the panel to the inverter and the output of the inverter can be connected to a three phase motor.

> The DSP will track at which point the maximum power can be extracted from the panel by varying the PWM and modulation frequency so the motor will run always extracting the maximum power from the panel and at a constant torque for the wide range of intensity of sunlight – morning till evening.

> This will give 35% extra energy which results in pumping 35% more water compared with the conventional three phase inverter + three phase pump or DC motor based pump.
