AGRICULTURAL & ESTATE PUMP CONTROL REPAIRS

Solar & Mains Pump Controller Repairs

A dead pump controller can mean a dry borehole, wilted crops, or an idle farm. We repair solar and mains-powered pump controllers at the component level — fixing drive stages, control boards, and sensor circuits — getting your water flowing again without the heavy expense and delay of replacing the whole unit.

DIAGNOSTICS & SYMPTOMS

Common Pump Controller Faults We Fix

  • Controller powers on but pump motor won’t start or run
  • Dry-run / well-sensor protection triggering falsely
  • Solar pump controller unlit dead or unresponsive to panel voltage
  • Erratic pump speed or low flow output despite full sunshine
  • Blown drive stages, power MOSFETs, or IGBTs after lightning
  • Corroded or water-damaged circuit boards and input terminals
  • Display error codes (overcurrent, overload, under-voltage trips)
  • Pressure switch or tank-full float switch signal input failure

TRANSPARENT WORKFLOW

Our Pump Controller Repair Process

1. Bench Testing

Dynamic bench diagnosis to test panel input response, drive output, sensor logic.

2. Quote

Upfront commercial estimate for your approval before we proceed with the actual repair

3. Repair

Replacing shorted components such as power transistors, damaged ICs, or burnt traces.

4. Load Testing

Load testing under simulated pump conditions to ensure reliable field operation.

5. Handover

Unit returned ready to wire back into your borehole or surface irrigation system.

Why Board-Level Controller Repair?

For small-scale farmers and commercial estates alike, writing off a pump controller due to a single burnt component is an unnecessary expense. Most faults stem from a isolated power surge, lightning strike, or failing driver IC. We pinpoint and replace only the damaged part, saving you substantial capital while cutting down on long shipping delays for new units.

Brands & Turnaround Times

We service popular solar DC brushless controllers, AC inverter pump drives, and automatic borehole controllers (including Lorentz, Veichi, Hober, Grundfos, and generic regional solar pump brands).

Initial bench diagnosis is completed within 24–48 hours. Most repairs are completed quickly so your irrigation schedule stays on track.
