Model Select

A.The power of solar panel = power of pump ×1.3   ,The voltage of solar panel = the voltage of pump 

The controller should be matched 

B.Select the batteries according to the following formulas: 

The use hour of battery = The battery capacity ÷(the machine power÷the battery voltage)×0.6 For example,the machine power is 200W, the battery capacity is 100AH,the voltage is 12V,and the battery is fully charged,then the use hour is:100÷(200÷12)×0.6=3.6hours 

C.The battery capacity= 

the use hour ÷0.6×(the machine power÷the battery voltage) For example,the machine power is 200W,the battery voltage is 12V,and the battery need to be used for 3.6hours,then the battery capacity is:3.6÷0.6×(200÷12)=100AH
