  • Can I use mains or generator power to run the pump on cloudy day?

    The controller does not have the input for mains or generator power but the pump can be powered by means of a DC power supply that can supply the controller the correct voltage and amperage for the pump to operate efficiently.

  • How far can I install the solar panels from the pump?
    The Solar pumps we use work on low voltage so extending the cable too far will affect the performance and thicker cables need to be used to counter the volt drop.

    We would not recommend extending the cable more than 100-120m depending on the size and voltage of the pump. It's best to increase the cable between the controller and pump and keep the cables between the controller and panels as short as possible to get the best efficiency out of the pump.

  • Do these pumps use brushes like other DC pumps?

    The motors that we use are AC low voltage motors which means that they do not work with brushes at all. The only wearable parts on the motors are the bearings and mechanical seals like normal AC motors.

  • Can I run this pump on an existing solar installation?

    It is possible to run the pump directly off of a battery bank. You will need to make sure that the voltage of the battery bank falls within the input range of the controller.

    2022/3/31 13:32:09
  • How do I determine the number of panels needed for my solar pump?

    The easiest way to determine this is to add 1.3 times on top of the pump wattage for minimum requirements and recommended would be 1.4 times. I.e. a 500w pump requires minimum 650w and recommended 700w to operate.

  • What is an open centrifugal pump?
    Centrifugal water pumps use centrifugal force to pressurize and move water from the inlet to the outlet. A rotating set of vanes (called an 'impeller') is spun by the pump shaft. As water is forced through the impeller, rotational energy is transferred from the impeller to the water, which gains velocity and pressure through the centrifugal force applied and is flung from the impeller. The volute (a spiral-shaped case) funnels the now-pressurized water to the outlet. Image below shows clockwise rotation as viewed from the motor mound.

    Ningbo Guanghan Solar Pump Industry is a factory specialized in manufacturing solar submersible pumps and solar surface pumps. The head office was established in 1989 in Daxi Town, Wenling City, the hometown of water pumps in China, and a branch factory was established in Jiangshan Town, Ningbo City in 2019. It is located near the highway intersection, very close to Ningbo Port and Shanghai Port, and the transportation is very convenient.

  • What is the permanent magnet synchronous motor

  • A permanent magnet synchronous motor (PMSM) uses permanent magnets embedded in the steel rotor to create a constant magnetic field. The stator carries windings connected to an AC supply to produce a rotating magnetic field. At synchronous speed the rotor poles lock to the rotating magnetic field. Permanent magnet synchronous motors are similar to brushless DC motors.
  • Because of the constant magnetic field in the rotor these cannot use induction windings for starting. These motors require a variable-frequency power source to start.
  • The main difference between a permanent magnet synchronous motor and an asynchronous motor is the rotor. Some studies seem to indicate that NdFeB permanent magnet synchronous motors are around 2 percent more efficient than the highest-efficiency (IE3) asynchronous motors—using the same stator laminations and similar variable-frequency speed controllers.
  • Permanent magnet motors have been used as gearless elevator motors since 2000.

    2022/3/30 13:16:05
  • Which is better--a DC or an AC pump?

    The DC pump can directly use the DC power generated by the solar panel to run the water pump. Reduce the power loss in the conversion process. Therefore, the DC pump is more efficient and requires fewer solar panels. The DC pump also does not require an inverter to convert the direct current generated by the solar panel into alternating current. Reduced costs.

     

    2022/3/30 13:08:21
  • Can the speed of the solar water pump be adjusted?

    Yes, the controllers come standard with a speed adjustment dial whereby you can reduce the speed of the motor if needed.

  • What is the difference between TPS, TPPC, TPSC series?
    TPS series are solar screw pumps. The characteristic of screw pump is high head and small flow. Suitable for domestic water supply.

    TPPC series are solar-powered plastic impeller solar deep well pumps. It is cost-effective, has a long service life, is more durable than a screw pump, and has a larger flow rate. However, the head is relatively small.

    TPSC series are solar submersible pumps with stainless steel impeller. Stainless steel impellers are more durable than plastic impellers, especially in waters with high sand content.
