JINTAI 4 inches 72v 1000w screw submersible solar water pump JS4 4.0 100

Solar water pump: 3 years
MPPT controller: 3years
Solar panels: 25 years
You can buy solar panels from us or just buy solar water pump and controller .
If the controller and motor damaged within 3 years, we will send you a new controller or motor for replacement.
If the impeller is damaged within 3 years, we will send you spare impellers for replacement.

Globally electricity prices are rising due to in fuel prices and the prices are bound to rise further .

In addition we are facing acute power shortage and are not able to supply electricity for agricultural purposes . solar pumping systems make efficient use of solar energy and convert it to electrical energy for pumping water to great heights .

The Finished Products include:
1. Solar pump with 3m cable, longer cable is available if required
2. MPPT Controller
3. Water level sensor or float switch:10meter cable, longer cable is available
4. Cable for solar panel: 6m, longer cable is available
5. Cable connector
6. Solar panels are option
7. Rope to hang the pump
8. Installation Manual 

ADVANCED TECHNOLOGY:

1.Application innovation
Compared with the traditional alternating current

machine,the efficiency is improved 25% by the permanent magnetism,direct current,brushless,non-sensor motor.
2.Technics innovation
Adopt double plastic package for rotor and stator,
motor insulation≥300MΩ,the motor security was much improved.
3.Structure innovation
Oil filling,convenient installation and environmental protection.

SOLAR PANELS AND BATTERIES SELECTION:
1. The power of solar panel=power of pump X 1.3, the voltage of solar panel=the voltage of pump, the controller should be matched
2. Select the batteries according to the following fomulas: The use hour of Battery=The battery capacity÷(the machine power÷the battery voltage) X 0.6 . For example,the machine power is 200w,the battery capacity is 100AH,the voltage is 12V,and the battery is fully charged,then the use hour is 100÷(200/12) x 0.6=3.6housrs.
3. The battery capacity=the use hour÷0.6 x (the machine power÷the battery voltage) For example,the machine power is 200w,the battery capacity is 12V,and the battery need to be used for 3.6 hours,the the battery capacity is: 3.6÷0.6 x (200÷12)=100AH
