It is an installation isolated from the electrical network that feeds up to 4 pumps on a common bus with a single PV generation plant. Bombeatec executed the turnkey project, which includes the installation of a new pump, automatic cleaning filter, solar trackers, solar panels, and the DC PUMPING STATION.
Thanks to the solar tracker, a higher and more constant generation power is obtained throughout the day, achieving the ideal irrigation pressures for irrigation.
Less than 30 milliseconds time response were achieved facing passing clouds, being most likely a first in the world of solar pumping.
The system is totally autonomous thanks to the DC PUMPING CONTROLLER, which performs an intelligent management of the system. The following functionalities should be highlighted:

Pump start/stop efficient management considering solar intermittency and cloud passages
Multipump management on common bus
Irrigation and fertigation programming
Wireless communications for managing solenoid valves and irrigation sectors
Integrated control of trackers
