Solar submersible pumps are water-lifting devices that utilize solar energy and operate underwater. They are suitable for scenarios such as drinking water for people and livestock, and agricultural irrigation in areas without electricity or in remote locations.
Check insulation resistance: Use a megohmmeter to measure the insulation resistance of the motor windings to ground. It should not be less than 500 MΩ (some products require ≥50 MΩ).
Confirm cable integrity: Check power cords and signal cables for damage, aging, or loose connections.
Verify system compatibility: Ensure the solar panel power, controller (including MPPT), and water pump rated voltage/current are compatible.
