With the growing adoption of solar water pumps in agricultural irrigation, rural water supply, and other applications, the importance of proper installation, safe operation, and regular maintenance has become increasingly clear. To help customers maximize performance and extend service life, INSOLA has outlined key guidelines for the safe and effective use of its solar pumps.
1. Scientific Installation: The Foundation of Safe Operation
Before installation, it is critical to verify that the well conditions meet the pump requirements:
Well Depth & Diameter: Ensure that the well dimensions match the pump model.
Immersion Depth: The pump should be submerged at least 3 meters below the water surface and kept at least 1 meter above the well bottom.
Water Quality: The water must be clean, with a sand content of no more than 0.01%, and a pH level between 6.5–8.5.
Well Verticality: The vertical deviation of the well pipe should not exceed 20 cm.
Cold-Region Precautions: In high-altitude or freezing areas, install pipes below the frost line or add a pressure relief valve to prevent damage from ice.
2. Safe Use: The Key to Longevity
Operating the pump under unsafe conditions may cause severe damage:
No Dry Running: Running the pump without water is strictly prohibited, as it may burn out the motor. Always confirm adequate water levels before startup.
Electrical Safety: All cable connections must be waterproof, and system parameters between solar panels, controllers, and pumps must match. Reverse polarity is forbidden.
Weather Protection: Disconnect the system during thunderstorms to avoid lightning-related equipment damage.
3. Regular Maintenance: Keeping Systems Reliable
Consistent maintenance ensures long-term stability and performance:
Troubleshooting: If abnormal noise, strong vibrations, or sudden stops occur, immediately cut off power and seek professional repair.
Do Not Disassemble: Avoid opening the motor or controller on your own.
Long-Term Storage: When not in use, drain the pump, and power it on for several minutes every 2–3 months to prevent component aging.
4. Prohibited Actions to Avoid Damage
To maintain safety and performance, the following actions are strictly forbidden:
Running the pump without a controller.
Using the pump in unclean water sources.
Operating with damaged solar panels or exposed wiring.
Striking the pump body or pulling the cable forcefully.
By following these guidelines, users can ensure the safe, efficient, and long-lasting operation of INSOLA solar water pumps. At INSOLA, we are committed to delivering sustainable water solutions that support agricultural productivity and improve access to clean water across diverse environments.
