Submersible pump Pedrollo FLUID SOLAR 2-6 0,75 kW on Pedrollo solar panels

The Pedrollo FLUID SOLAR 2-6 is an innovative submersible borehole pump designed for ecological and economical water supply. This high-tech unit exclusively uses the energy from solar photovoltaic panels to pump clean water from boreholes and wells, making it ideal for filling tanks in off-grid systems. With a power of 0.75 kW, it ensures a reliable water supply for domestic and agricultural needs.

Intelligent Control System and Maximum Efficiency

The heart of the Pedrollo FLUID SOLAR 2-6 is a highly efficient brushless motor with permanent magnets and integrated electronic control. This intelligent system optimizes the use of solar energy: 

▪️Automatic speed regulation: The electronics convert the output voltage from the solar panels and regulate the motor's rotational speed to maximize the use of available energy. On a sunny day, the pump operates at high speed with high efficiency, ensuring maximum performance. On a cloudy day, the speed will be lower, and the performance will match the insolation level. 

▪️Protection against incorrect startup: The built-in control logic prevents the pump from starting if the solar radiation is too weak and the rotational speed would be insufficient for correct operation, protecting the equipment from wear. 

▪️Efficiency under varying conditions: The pump demonstrates high performance even under partial illumination, adapting to solar radiation conditions. For example, at 1000 W/m² and 100 V DC open circuit modules, it shows maximum performance, while at 300 W/m² and 70 V DC, it provides adapted but stable operation.

Ease of Installation and Reliability

FLUID SOLAR pumps are designed for easy installation. Photovoltaic panels are connected in series, forming strings, each of which is connected to the control unit. The pump itself connects to the control unit via a special cable, which is joined to the pump's electrical power cable using a heat-shrinkable sleeve for reliable insulation. The entire system must be grounded for safety.

Technical Specifications:

▪️Pump type: Submersible multistage (4 inches) powered by photovoltaic modules. 

▪️Motor: High-efficiency with permanent magnets, integrated electronic control. 

▪️Photovoltaic modules: Compatible with high-efficiency PANASONIC modules (e.g., model VBHN240SJ25). 

▪️Installation requirements (for P1=750 W, close to 0.75 kW): 

▪️Number of modules: Four photovoltaic modules are required to achieve nominal power. 

▪️Module voltage: The DC open-circuit voltage of each module must be within 35 ÷ 50 V. 

▪️Total power: The total nominal power of all four modules must be at least 980 W.

The Pedrollo FLUID SOLAR 2-6 is an advanced solution for those seeking autonomous, environmentally friendly, and highly efficient water supply, utilizing the unlimited resource of solar energy. Invest in the future with this reliable and smart pump!
