Start with the pump duty point and the motor nameplate. A useful request includes the target flow, total dynamic head, motor voltage, phase, full-load current and rated power.
Describe the available supply
Share the PV module data, planned series and parallel layout, and whether a grid or generator source is available. The drive supplier needs this information to confirm input voltage limits and operating range.
Describe the installation
Include cable lengths, mounting environment, temperature, enclosure requirements and any water-level or pressure controls. Ask for confirmation of the selected variant and its installation requirements.
