Advantage of Built-in MPPT DC Solar Water Pump
stainless steel kit solar pump for home small solar water pump with internal controller mini solar pump china solar pump deep well solar pump china submersible solar pump submersible borehole solar pump12v solar pump solar pump pond.
1. DC input, wide working voltage range(10v-22v).
2. Made of stainless steel, non-sensor shielding motor, motor efficiency over 90%.
3. Brushless motor is used inside, the working time is 10 times longer than the brush motor.
4. The controller is internal which means the pump can be directly connected to solar panel.
5. Built-in MPPT which can make the best use of the solar energy.
6. This product is very suitable for water-lacking area and power shortage area.
7. Over-voltage protection / Under-voltage protection / Over-current protection / Over-load protection.
Applications of Built-in MPPT DC Solar Water Pump
Village or family water supply
Water supply for farm
Garden/courtyard irrigation system
Swimming pool filling
Water supply for bivouac or camping car
Solar water circulating system
Renewable energy projects
Installation of Built-in Mppt DC Solar Water Pump
1.This pump is a solar powered water pump, 18v is ideal input voltage. The solar panels' power should be about 2 times bigger than the pump. 2 or 3 pcs 12 volts batteries connected in parallel also can be power source.
2. 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.
3. 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.
4. If your solar panel kit is not powerful enough and you don't want to add more, a couple of 12v batteries 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.
FAQ of Built-in MPPT DC Solar Water Pump
Q. How to choose a proper size pump for my well?
A. The diameter of the well casing at least should be bigger than the pump’s diameter.
Q. What's the difference between max lift and working lift?
A. Max lift means the flow rate will be 0 at that height because the pump's actual flow rate will be less and less as the working lift increases; recommended working lift is the reasonable height to get sufficient water.
Q. Can I test the pump without water?
A.The submersible pump’s motor and internal controller are immersion, the motor and controller will be overheating if there is no water go through them, therefore the pump should be fully submerged in water.
Q. How to extend the pump’s service life?
A. 1) Put the pump in proper depth range, make sure the pump isn’t overloaded. 2) Make sure the pump is fully submerged in water. 3) Make a sleeve for the pump as an extra strainer if the water contains too much impurities. 4) Check the pump’s intake and outlet regularly if the water is not very clean.
Q. What is your after-sales service?
A. If the pump fails because of quality problem, Please take some actual pictures and record a detailed video and send to us. We will deliver a new pump free after we verify, the shipping cost is shared by both buyer.
