Designed to drive centrifugal and submersible pumps, the new CFW500 Solar Pump Drive turns solar energy, provided from photoelectric panels, into hydraulic energy, bringing great efficiency and maximising system availability. It also offers automatic control of pump starting and stopping, depending on the availability of solar energy or pressure level.

Main Characteristics:

  • Continuous maximum power point tracking (MPPT)
  • Double PID for simultaneously controlling of both DC voltage and pipeline pressure
  • Counter for working hours and generated kWh indication
  • Up to four distinct speed and pressure setpoints
  • Sleep/Wake up function triggered by DC voltage or pipeline pressure
  • Hybrid power source available1 (solar panels + gensets) to increase the available operational time for periods of low solar irradiation
  • Scalar or Vector control
  • Modbus-RTU RS485 communication
  • Side-by-side mounting possible
  • Dry pump protection
  • Overpressure and broken pipe protection
  • Simple programming
  • Available for ambient temperature up to 50°C without derating. Maximum ambient temperature of 60°C with derating
  • Possibility to operate in off-grid systems
  • Smart thermal management
  • Automatic MPPT (Maximum Power Point Tracking) efficiency higher than 99 per cent
  • 1 Requires solar irradiation sensor
  • Motors, drives and engines
