Taifu DC Brushless Solar Submersible Pump, 24V, 250W, External Drive, 26 m, 3.5 m³/h

The Taifu 24V 250W DC Submersible Pump is a high-efficiency water supply system designed for locations without grid electricity or where you want to reduce energy costs to zero. The most important feature that sets this product apart from its competitors is that it comes with an external control panel (driver board).

The external drive unit protects the pump from voltage fluctuations coming directly from the solar panels or battery, provides a soft-start feature, and allows well/tank sensors to be connected.

• Direct Solar Operation: With compatible solar panels, you can pump water continuously during the day using free solar energy.

• Battery Operation: With 24V battery banks (e.g., 2 × 12V batteries connected in series), you can continue irrigating even when there is no sunlight.

• External Drive (Control Panel) Advantage: Because the drive is housed outside the pump rather than on an internal circuit board, servicing in the event of a fault is much easier. Sensor inputs are also available to stop the pump automatically when the well runs dry.

• Brushless DC Motor: It lasts significantly longer than brushed motors, requires no maintenance, and operates at higher efficiency.

• Stainless Steel Casing: Features a stainless steel casing that is resistant to harsh well water conditions and corrosion.

• Drip irrigation for hobby gardens and small agricultural plots.

• Filling water tanks for caravans, country houses, and container living spaces.

• Livestock watering (trough-filling) systems.

• Drawing water from deep wells or cisterns.

• Undervoltage protection
• Overvoltage protection
• Overcurrent protection
• Protection against motor lock-up and overheating
• Protection against well running dry
• Automatic restart when water returns to the well
• When pumping to a tank, the pump stops automatically when the tank is full and resumes automatically when the water level drops.
• Can be integrated into automatic irrigation systems via output sensors.
• You can control and adjust the motor's operating speed to suit your needs.
• After protecting the motor from overheating, current/voltage faults, or a flooded motor, the pump restarts automatically once conditions return to normal.
• A battery connection can be made to run the pump when sunlight is absent or insufficient.
• If the control panel fails, you can service it without pulling the pump out of the well, unlike pumps with internal circuit boards.

To get maximum performance from this pump, the following power systems are recommended:

• Panel Recommendation: For the pump to operate at full performance, a solar panel of approximately 350W – 400W is recommended (e.g., 2 × 205W panels or 1 × 400W panel).

• Cable Selection: To prevent voltage drop as well depth increases, it is recommended to use DC-rated cable with an appropriate cross-section (at least 2×2.5 mm², or 2×4 mm² depending on the distance).
