Solar Pump Systems

SPCS/H COMBINER cabinets with hybrid power input solar frequency converters are capable of driving solar pump systems with three-phase AC induction motors.
Motor power range: 22 kW to 92 kW

The solar pumping system cabinets are designed to be built-in autonomous solar pump installations.

They are suitable for driving standard three-phase AC induction motors in solar pump installations.

The system is modular and easy to use. Covering a wide range of applicable motor powers and implements user friendly “plug & play” design for quick installation and reliable operation.

There are different options for system monitoring, parameters adjustment and control. Different operation modes fulfilment and system modules combination for covering different requirements and providing capability for integration and best fitting in a variety of solar pumping applications – water treatment and water supply systems, for instance purification, filtration and desalination systems, irrigation systems, flood control, etc.

Solar Pump Application

Solar Pump System is implemented with hybrid power source input, from PV Plant and from Three-phase 400V (50/60Hz) AC source (Grid and/or Diesel Gen-Set). The system integrates all of the needed inputs and outputs for autonomous self-managing operation. It operates automatically while optimizing the energy consumption by giving priority to PV power source.
