JNTECH solar pumping system consists of three main parts: solar panels, solar pumping inverter, three phase AC pump.
The solar pumping inverter converts DC power produced by solar panel to AC power which drives AC pump to pump water
from borehole, river, lake etc. to storage device or directly using in agricuture irrigation or water supply. This kind of system
using solar energy directly without battery storage. System is working on day time.
UNICEF100HP Solar Water Pumping System was installed in Sadah Yemen for Irrigation and Village Water Supply for local
people. It solved local water crisis, took big benefit to local people.

2.Solar Array and Parameters
Total 320pcs 330W Class A crystalline solar panels were used in this system, total 105.6kw,the connection is 20 strings, each
string 16pcs solar panels. Warranty: 10 years.

Product features:
♦ Maximum Power Point Tracking (MPPT) for Optimum Solar Performance.
Wide MPPT range from 460~ 850Vdc, makes high efficiency and long working time.
♦ Automatic start and shut off according to solar intensity. No need manual operation once started.
♦ Soft start controlling in rush current, to avoid motor burning.
♦ IP65 design for outdoor application. Waterproof and against dust in desert area.
♦ Drive power-matching three phase AC pump. The matching power with pump is 1:1.for example, 75kw
AC pump, we take 75kw inverter.
♦ LCD screen display.
You can see any parameters from LCD screen, easier for engineer’s installation work.
♦ Optional RS485/GPRS communication.
♦ 3 years warranty
