Kary 24v Solar Water Pump Lift 20m 2000l/h Brushless Submersible Pump Farm Water Pump External Controller 3FLD2-20-24-210

Products Brief Introduction:
DC solar submersible pump is an environmentally-friendly water supply solution. Dc solar submersible pump is fitted with a permanent magnet motor which enables the efficient use of energy from nature. The dc solar submersible pump offers the perfect water supply solution in remote areas where water is scarce, and the power supply is non-existent or unreliable.
DC solar submersible pump adapt to the characteristic weather profile of any given area. A battery backup system can store the extra energy generated and take over when the energy from nature is not available.
Products Advantage
1. Made of stainless steel, non-sensor shielding motor, motor efficiency over 90%.
2. Permanent magnet, brushless DC motor for long lifetime.
3. Powered by solar panel directly, fully automatic operation, remote operation safeguards.
4. Advanced controller with MPPT technology for maximum solar power.
5. Prevent frequent start-up of low solar power, the controller prolongs the motor lifetime.
6. The pump includes Over-voltage protection / Under-voltage protection / Over-current protection / Over-load protection / Lightning protection.
7.DC input, wide working voltage range(10v-22v).
8.The controller is internal which means the pump can be directly connected to solar panel.
Applications:
All products technical data :
Installation
1.Max head = 1.5 times * H – 2 times * H.
H = vertical distance (well depth + tank height) + horizontal distance (horizontal distance from well to tank) / 10.
2.Solar panel voltage = 1.5 times the pump voltage
Solar panel power = 2 times the pump power.
If you only need the pump to work in the sun, it can be connected directly to a solar panel.
If the sun is not so good, you can use more solar panels.
If you still need the pump to work at night, the controller and battery are needed even on cloudy and rainy days.
3. Connect the pump to solar panels directly, if the total length of the cable between pump and solar panel is longer than 100fts, we strongly recommend 9 or 8AWG wire.
4. Safety rope or wire is very important for deep well pumps, because the safety rope or cable will be the only way to retrieve the pump from the bottom of the well, we recommend a good stainless-steel cable rather than rope.
5. If your solar panel kit is not powerful enough and you don’t want to add more, battery is a good option, they can help to hold the input voltage above the “low voltage cut off point”, however, sufficient solar panels is still the best power source.
Warm Tips:
1.Do not mix the positive(+) and negative(-) connection.
2.Do not operate long time while there is no water in the pump.
3.Don’t overload the pump for long time, it will damage the motor.
4.The pump is submersible which means it must be full submerged in the water.
