4.Introduction of Jntech solar pumping system
Jntech solar pumping system consists of solar panels, solar pumping inverter, three phase AC pump and storage device.The solar pumping inverter converts the DC power from solar panels to AC power which drives AC pump to pump the water from borehole, lake, river etc. to the storage device.
Meanwhile, the application of AC Power Pack add grid utility/DG as power supplement or backup for solar energy, can keep pumping system working 24 hours a day.
The power drawn from AC source is adjustable according to the intensity of solar energy.
5.Application of solar pumping system
Solar pumping system mainly used for daily water using, agricultural irrigation, forest irrigation, desert control, pasture animal husbandry, rural town and village water supply, desalinization of sea water,scenic fountain etc.
