IRRISUN DRIVE MANAGER 100% SOLAR CENTER PIVOT IRRIGATION AND DRIVE TRAIN SOLUTION

 

Off the shelf stand alone solar PV systems cannot properly drive center-pivot irrigation systems and pumps:

 

3 phase supply needed: Electrical driven pumps need 3 phase AC supplies with  voltages from 380V up to 460V. Off the shelf stand alone PV Inverters produce 110V or 220V single or split phase AC, which is unsuitable for 3 phase pumps and  pivot  motors.

 

Very high inrush currents:  Both pivot motors and large pumps have very high inrush currents. Center pivots can up to 9 motors that are starting and stopping several times per hour,  the driving devices have thus to cope with currents which can as high as 20 times the normal operation current.

 

Automatic system  restart / redirect:  Most center pivot systems run on a manual start and movement direction indication basis.  100% Solar operated systems stop at night or when it is very cloudy. Even for one system it is desireable to  manages start stop operations and movement direction in an automatic way.

 

Sizing: Some of the above issues can be solved by installing much larger PV systems and oversized electronics.  WATTKRAFT IRRISUN however, solves all of the above problems using the smallest possible installation saving on capital expenditures and financing costs.
