Solar Pump Drives Selection Guide: Technical Criteria & Application Standards
Solar Pump Drives selection guide: technical parameters, mounting and compliance standards, and GMT comparison.
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. The Solar Pump Drives category on Welibaba includes 11 active models from leading manufacturers such as GMT.
Key Technical Parameters for Selecting Solar Pump Drives
To specify the right Solar Pump Drives model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Alternative AC Generator Power | 11 kVA, 17 kVA, 21 kVA, 24 kVA | Verify against project schedule and load calculation |
| Alternative AC Generator Maximum Current (RMS) | 10.5 A, 14.6 A, 2.3 A, 20.5 A | Verify against project schedule and load calculation |
| Number of Analog Inputs | 2 | Verify against project schedule and load calculation |
| Alternative AC Generator Input Voltage | 1 faz 220–240 V, 3 faz 380–480 V | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Variable Frequency Drives (Frequency Inverters).
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Braking Resistors, Drive Accessories.
