Descriptions  

(1)  Selecting the solar panel of the pumping system

If you have not purchased a complete system from your supplier, the following formulae will be useful. Your pump supplier will be

able to help you with panel selection.

a. Solar PV panel (solar panel) selection

power of PV panels (watts) =Rated  power of pump (watts) x( 1. 3  ~ 1.6)

voltage of solar panel = Rated  voltage of pump (volt) x 1.5

the controller will already be matched to the pump by your supplier

eg  A 300 watt pump needs a minimum of 390 watts of PV panels to drive it (300w x 1.3 = 390w)

b. You may need combinations of panels, especially for the larger pumps. During connection of solar panels, you have to get the

solar panels in series to reach the rated voltage of the pump, then in parallel to reach the rated current of the pump.

Panels in parallel double the current and the wattage of the panels

Panels in series double the voltage and the wattage of the panels

e.g. 2 x 12V/ 100 W panels in parallel →    12 V/200W system

       2 x 12V/ 100 W  panels in series   →    24V/200W system

(2) Selecting the battery of the pumping system

Current drawn by the pump = pump power / the voltage

In the case of a 24 volt 300 watt pump

300 watts divided by 24 = 12.5 amps

2 x 100AH 12volt batteries in series = 100 Ah at 24 volts

100Ah divided by 12.5 amps x 0.6 = 4.8 hours of backup

Batteries in parallel, add the Ah, voltage stays the same

Batteries in series, add the voltage, Ah stays the same

2. INSTALLATION

(1)   Function of solar pump controller box

Low voltage protection(It is automatic)

Over voltage protection(It is automatic)

a.    Over current protection(It is automatic)

b.    Protection for low water level in well (WC,WH sensors)

c.    Protection for full water level in tank (TC,TH sensors)

d.    Controlling running speed of motor (Speed regulator)

e.    Delay for restart working function (Timer regulator is to be set a period of rest time after the pump stops working from low

       water level protection in well)

f.     MPPT function. (Maximum Power Point Tracking)

g.    Battery(Battery can be connected to the controller directly for storing electricity.)

(2)   Wiring the controller box

Before you start wiring the control box, switch must be in the off position.

Wire the pump, panels to the control box as per the wiring diagram below. Both the pump and controller are labeled with “U”, ”V” and “W”.

Make sure to be correspondingly connected and not touch with each other.

Application 

If you do not know how to choose the model,pls tell the question below,i will choose for you

1 What is your requirements for the flow rate of the pump? that means how many cubmic meter water you need per hour.
2  what is your requirements for H1 =?  H2= ? H3= ?  H4 = ?

Please leave us message and we will reply ASAP.Thank you !
