3" 4" DC Brushless Submersible Solar Water Pump Price List, Screw Pump

Warranty:


3 Year for motor and controller. Solar panel 20 years(Optional)

 


Installation

 1. Wiring the pump
 Connecting a longer cable to the pump,(size of cable must be at least 1.5mm²)

Use the parts contained in the cable connector kit( heat-shrink tube and tape) to connect a longer supply wire to the pump. If you don't have a heat gun to shrink the tube, the barrel of your soldering iron will do or you can use a butane torch but with great care so you don't melt the insulation or set it on fire. Bare the insulation back as shown above.
A. Layout the components needed to make the join 
B. Put the large diameter piece of heat-shrink over the main cable and then the smaller diameter pieces over the individual wires, keep the heat-shrink back away from the joints as you solder them. Any heat transfer will prematurely shrink the heat-shrink.
C.  Slide the small heat-shrink over the soldered joints and heat using a heat gun or alternative heat source to shrink the sleeve down over the wires.
D. Wrap the tape over the sealed joints
E. Finally slide the large diameter heat-shrink over the completed joint and shrink to it.

Place the pump in water before you start wiring the controller box this will allow the pump to go through the pre-conditioning required. Do not put the pump in its final position until you have tested it, unless it is easy to see and remove.

 

1. Solar pump control box

  A. Low-voltage protection (it is automatic)
  B. over-current protection( it is automatic)
  C. protection for low water level in well( A B sensor)
  D. protection for full water level in tank( L H sensor)
  E. Controlling running speed of motor( speed regulator)
  F. Delay working when full water in tank( a timer inside can delay working for 30 seconds when the tank going to not full)
  G. MPPT function.(maximum power point tracking)
  H. Battery is optional.( battery can be used with solar charger battery system)
