Solar Pumping

Our versatile solar drives are capable of operating with any type of motor (Inductive, permanent magnets, SynRM and Brushless DC).

 

Manufactured in Spain with the protection standards IP20, IP55 and IP66 and integrating a dual PI to smooth the operation of your pump, it is one of the most complete solutions for solar pumping that can be found in the market.

Key Features

• The maximum power point tracking (MPPT) algorithm continuously adapts the system load for maximum system output power under varying conditions of irradiance and temperature. MPPT is the best choice for getting the maximum pumping delivery from your PV array under all conditions.

• Extended DC operative voltage range, 345–800Vdc HV, 185–410Vdc LV which increases the system operational time per day and reducing unnecessary stoppages caused by the low array voltages present during dawn and dusk.

• Advanced PI set up built-in dual PI set point, dead-band and PI transition error, creating very stable system control that responds slowly to small changes in irradiance but responds quickly to large changes in solar irradiance.

• Advanced pump protection functions, dry run protection, pipe-burst detection, pump clean function and pump stir function. These protection functions are designed for a reliable system whilst reducing the risk of damage to the pump.

• The Pipe-Fill function, allows a configurable period for the pipe to fill slowly before operating normally and pipe-burst detection can be activated.

• Remote monitoring. All data can be accessed using Modbus RTU or CANopen communications onboard or Ethernet pluggable option modules.

• 3 different methods for PID Sleep and wake up. An optional external irradiance sensor could be selected to re-start the pump when sufficient energy is available from the sun.

• Dual supply mode. The P2 Solar pump can be powered by a DC voltage coming from PV arrays or the traditional grid or generator power.

• PLC integrated to customize the more demanding applications where the user may need to control, for example, valve actuators or monitor system water pressure to stop the drive above defined limits. The onboard PLC provides a high degree of flexibility.

• Compatibility with all types of motors, the P2 Solar Pump is compatible with AC induction motors, Permanent Magnet (PM) motors, Synchronous Reluctance (SynRM) motors, Brushless DC (BLDC) motors.

• Digital inputs for tank high water level and well low water detection, forcing the driver to stop when the destination tank is full or the water well is empty.

• The second analog input for pressure monitoring can be used just to monitor system pressure locally or remotely or to stop the pump if the water pressure exceeds a configured level.

• Irradiance level can be monitored on the drive display if an irradiance sensor is connected to the drive, the level can be indicated on the drive display.

• Optional Sine-Wave filters, allowing the increased distance between the drive installation and the pump location which is very common on deep well water applications.

• Available in different IP enclosures IP20, IP55, IP66, offering the best choice for each installation. The appropriate IP rating should be selected according to the location of the installation which can in some circumstances eliminate additional enclosures.
