Photo voltaic pump control box
  A. Low-voltage defense (it is computerized)
  B. more than-recent protection( it is computerized)
  C. security for minimal drinking water amount in properly( A B sensor)
  D. protection for full drinking water level in tank( L H sensor)
  E. Controlling working speed of motor( velocity regulator)
  F. Delay operating when total drinking water in tank( a timer within can hold off operating for 30 seconds when the tank likely to not complete)
  G. MPPT perform.(highest electrical power stage tracking)
  H. Battery is optional.( battery can be utilised with solar charger battery technique)

 Wiring the pump
 Connecting a longer cable to the pump,(dimensions of cable must be at least one.5mm²)

Use the areas contained in the cable connector kit( heat-shrink tube and tape) to join a longer supply wire to the pump. If you never 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 fantastic care so you will not melt the insulation or established it on fire. Bare the insulation back as proven earlier mentioned.
A. Layout the factors needed to make the join 
B. Set the big diameter piece of heat-shrink over the major cable and then the smaller diameter pieces over the individual wires, hold the warmth-shrink back away from the joints as you solder them. Any heat transfer will prematurely shrink the warmth-shrink.
C.  Slide the modest warmth-shrink above the soldered joints and warmth utilizing a heat gun or alternative heat source to shrink the sleeve down above the wires.
D. Wrap the tape above the sealed joints
E. Lastly slide the big diameter warmth-shrink more than the concluded joint and shrink to it.

Spot the pump in h2o ahead of you start off wiring the controller box this will allow the pump to go by means of the pre-conditioning essential. Do not put the pump in its ultimate situation till you have examined it, unless it is simple to see and take away.
