1. Simple Introduction
JNTECH Solar Pumping system consists of solar panels, solar pump inverter, AC pump and water storage
device. Solar pump inverter converts DC power produced by solar panels to AC power with drives AC pump
to pump water from borehole, river, lake etc. to water storage device. Inverter applies high efficiency MPPT
algorithm to maximize power harvested from solar panels. It will make the system to maximize efficiency to
get the water as much as possible. The solar pumping system fulfills concept of low carbon, energy
conservation, environmental protetion to inprove the living standard in water-deficient area.
Meanwhile, the application of AC PowerPack add grid utility/DG as power supplement or backup forsolar
energy, can keep pumping system working 24 hours a day.
