3‑Inch Brushless DC Solar Submersible Deep Well Pump with External MPPT Controller, Stainless Steel Solar Water Pump for Farm Irrigation, Livestock Drinking and Off‑Grid Household Water Supply

This reliable 3‑inch solar submersible deep‑well pump is equipped with high‑quality brushless DC motor and independent external MPPT controller, delivering long service life and stable performance for off‑grid water lifting projects.
 
The advanced brushless motor runs with low noise and low heat loss, greatly extending working life compared with ordinary motors. The separate external MPPT controller maximizes solar power utilization, allowing the pump to work efficiently even under cloudy and changing sunlight conditions. The whole pump body is made of stainless steel, anti‑rust and corrosion‑resistant for long‑time underwater operation. Its standard 3‑inch outer diameter fits most common 3‑inch well bores, easy to install inside deep wells.
 
Installation Guidance
 
1. Place the pump completely submerged under water, keep proper distance from the well bottom to avoid sand and sediment damage.
2. Strictly follow wiring diagram to connect solar panels with the external MPPT controller.
3. Ensure solar panel voltage and current stay within the controller’s rated parameters, do not exceed maximum input limits.
4. Never run the pump without water, dry‑running will cause permanent damage to the motor.
5. Check all cable connections are tight before starting operation. Inspect consumable wearing parts regularly to maintain good performance.
