Solar Pump Drives

Solar pump drives are frequency inverters that convert the DC voltage from solar panels into variable-frequency AC voltage and run submersible and centrifugal pump motors directly from the panels without batteries. They are used to pump water by adjusting pump speed according to irradiance in agricultural irrigation and drinking water wells where there is no mains supply or energy costs are high. The category includes the ABB ACQ80 series and the GMT SPIN2 series; GMT models are listed in powers such as 5.5 kW, 11 kW, 22 kW and 37 kW, and ABB models at 380-480 V AC, three-phase and in different frame sizes. The product data for the ABB series states the MPPT algorithm and the switchover to mains supply when there is no sunlight. Choose the drive according to the pump motor's power, rated current and voltage, whether the panel array's power and open-circuit voltage suit the drive's DC input limits, and whether you need redundant operation with the mains. They must not be confused with solar inverters that feed energy into the grid; a solar pump drive does not transfer panel energy to the grid, it only drives the pump motor.

How to choose Solar Pump Drives

Solar pump drives are frequency inverters that convert the DC voltage from solar panels into variable-frequency AC voltage and run submersible and centrifugal pump motors directly from the panels without batteries. They are used to pump water by adjusting pump speed according to irradiance in agricultural irrigation and drinking water wells where there is no mains supply or energy costs are high.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
