Applications

 

SLR01/02, solar water pump drives, support either PV panel DC input or grid AC input. These inverters can quickly capture and track the maximum power point according to the radiation intensity, and always maintain the maximum output power of the system in speed non-limited mode. Users are using these inverters in the regions which do not have wide coverage of grid electricity or where the availability of electricity is uncertain. Also, many people opt to use solar pump drives for the purpose of environmental protection, or to reduce the cost of operation such as replacing traditional diesel generators used for pumping water. 

 

 

Water treatment	Farm irrigation	Farming pool water supply	More

 

SLR01 cases in Morocco   The whole system includes 45 pieces of 300W PV panels, one 7.5kW motor and one SLR01-4T7.5B-G4 PV drive. Cloudy days can be detected automatically to prevent frequent start. In this way, the motor working life can be extended to the maximum extent. Besides, AC grid supply is also available when the sunlight is weak. In this mode, the function of constant pressure mode is available when X3 terminal is active.  GTAKE has mastered more precise MPPT algorithm compared with many other brands. GTAKE PV drives for water pump are warmly welcomed and highly appraised by customers worldwide.

 

 

 Production

 

In production, rigorous quality control is implemented on components, circuit boards, and the finished goods, assuring products without defects.
