Pump Controllers — DC, AC & Hybrid Control Units for Submersible Pumps

A pump controller is the electronic control unit that manages power delivery, motor protection, and run conditions for your submersible water pump — whether it's powered by solar panels, grid electricity, or a hybrid of both. Choosing the correct controller for your pump model and power source is essential for reliable operation and long-term motor protection, particularly for boreholes running on solar power across coastal Kenya where voltage conditions can vary through the day.

Our range covers DC controllers for solar-only submersible pumps, AC controllers for single-phase and three-phase grid-powered pumps, and AD (hybrid AC/DC) controllers for pumps designed to run on either solar or grid power depending on availability. Each controller is matched to a specific pump wattage and model — from smaller 600W domestic units up to 3000W+ systems for larger farm and community boreholes.

For coastal properties in Mombasa, Malindi, Diani, Kilifi, and Lamu dealing with unreliable grid power, DC and hybrid AD controllers are especially useful, allowing pumps to run purely on solar during the day and switch to grid backup when needed. Inland customers running three-phase agricultural or community systems will find dedicated 3-phase AC controllers sized for larger motor loads.

CoastalSolar Africa supplies and fits the correct controller for your specific DOYIN pump model, ensuring proper voltage matching and motor protection — avoid running any submersible pump without the matching rated controller, as this can damage the motor.

Category Highlights:

• DC Controllers: For solar-only submersible pumps, 600W–3000W range
• AC Controllers: Single-phase, for grid-powered pumps, matched by pump model
• AC Controllers (3-Phase): For larger three-phase pumps, 1.5HP–10HP range
• AD (Hybrid) Controllers: Support both AC and DC input for flexible solar/grid operation, 800W–3000W range
• Matched by model: Each controller is paired to specific pump wattage/HP for correct voltage and current handling
