|Minimum Order Quantity||1 Piece|
|Voltage||380 - 480VAC|
1. Above scheme does not show the interlocks for running the drive with three phase supply. External contactor logic will be required for changing from DC to AC supply.
2.Safety interlocks and isolator must be used to isolate the drive from PV source are not indicated in this scheme.Product selection:
1. Drive selection: Sx2000 drive (400V class) drive as per motor rated current.
2. Total Vmpp = 560 to 610 VDC
Ex. If Vmpp of one panel = 30V then total panels required are 600 V / 30 V = 20 nos.
3. Under voltage level for 400V class drives is 360VDC Under voltage level for 200V class drives is 180VDC
4. Total Voc should not be higher than 760VDC
5. Impp = Motor kW * 1300 / Total Vmpp
Impp = Motor FLC * 0.75
6. Proper enclosure shall be selected based on the site conditions.
7. In case drive to motor cable distance is higher than 150-200 feet, an AC reactor shall be used at the output of drive.Frequent long-time electricity failure is a major problem today which affects water-pumping for major applications like Irrigation, Drinking-water supply Industry. Need of a permanent solution for water-pumping was necessary till date we have a solution for this problem. Everyday ample sunlight is available is Asia, which shall power our Solar DC pump sets for water-pumping applications. This Solar Energy can also be stored in battery these batteries can power the pumps during nights.
