9.Controller:
(1)Waterproof grade:IP65
(2)Ambient temperature:-15ºC~60ºC
(3)MPPT function,the solar power utilization rate is higher.
(4)Automatic charging function:Guarantee the pump normally working,meanwhile charge the battery;And when there is no sunshine,the battery can make the pump continuously working.
(5)LED displays the power ,voltage,current,speed etc working condition.
(6)Frequency conversion function:It can automatically run with frequency conversion according to the solar power ,and user also can change the speed of pump manually.
(7)Automatically start and stop working.
(8)Waterproof and leak-proof;Double seal effect.
(9)Soft start:No impulse current,protect the pump motor.
(10)High voltage/Low voltage/Over-current/High temperature protection
10.2 years warranty.

The water-cooled motor in the solar water pump has the following advantages:

Excellent working performance: The water-cooled motor is equipped with a unique cooling system, has good low-frequency characteristics, high overload capacity, stable operation, high reliability, and a wide range of applications.
Efficient heat dissipation: Water has a large specific heat, and the water-cooled motor can effectively maintain low-temperature operation at high power output, prevent the motor from overheating, and maintain stable performance.
Small size and light weight: Compared with air-cooled motors, water-cooled motors are smaller, lighter, and have a high energy density, which makes the design more compact and provides more flexibility for equipment layout.
Low noise: The noise of water-cooled motors is usually lower than that of air-cooled motors. This is because the resistance and flow of water flow are relatively stable, making the equipment quieter when running.
Better temperature control: The water cooling system can control the motor temperature more accurately, ensuring that each working link remains within the ideal temperature range, thereby improving the efficiency and life of the motor.
Suitable for high-performance needs: For high-power electric vehicles, electric cranes, electric forklifts, etc., water-cooled motors provide stability guarantees.
Brushless structure: The water-cooled motor has a brushless structure, excellent load characteristics, good low-speed performance, large starting torque, small starting current, which can meet the needs of frequent starting of electric vehicles and save electricity.
Long life and low maintenance: The water-cooled motor does not produce sparks, does not need to replace carbon brushes, has a compact structure, strong overload capacity and long service life.
Good energy feedback effect: The water-cooled motor rotor has a strong magnetic field, has good power generation effect when sliding and braking, does not need to absorb battery power for excitation, has good energy feedback effect, and has good electric braking effect.
Environmental protection: The water-cooled motor in the solar water pump does not produce any solid, liquid and gaseous harmful substances, which is absolutely environmentally friendly.
Fully automatic operation, no manual supervision required: The solar water pump system can be fully automatic, no manual supervision required, which reduces maintenance costs and improves reliability.
Wide voltage operation: Various required parameters can be adjusted through the winding of the stator, and can be operated at a wide voltage.

Q:Where is your loading port?
A: Ningbo port, China.
Q: Is it all right to make customer's own brand name?
 A: Can make OEM if order quantity reached 1000pcs totally.
Q: What is your payment term?
A: 30% in advance, 70% balance the B/L or T/T.
Q: What is the warranty of the product?
A: We offer 2 years product life guarantee and a generous 2 years warranty on all purchases that begin with the BL.
Q: What information shall I provide you when I need your offer?
A: Normally, we need customer to supply the pump flow, total head, pump material (copper wire or aluminum wire? Stator length), voltage, frequency, etc, so we can quote exactly what customer need.
Q: Can you accept customized products?
A: Yes we accept your specific order if you could provide us with your requirements.
Q: Will you supply any spare parts with the pumps?
A: Yes, we can supply for example: tank, flexible hose, pressure switch, pressure gauge, brass connector, cable, etc.
Q: Is there any leakage problem of this pump?
A: Some factory may have such problem, but we solved it very well, by using good material of pump casing, O-ring, and they fit each other perfect. We use 8 screw on the pump head while others may use only 6 screw to save cost. We test 100% and long time for the pump head part, to make sure there is no leakage problem.
