How can solar water pumps be made to reduce the occurrence of sudden malfunctions?

With the widespread application of solar water pumps in agricultural irrigation, water supply in remote areas, and other fields, solar water pumps have become important equipment due to their energy-saving and environmentally friendly advantages. However, their outdoor operation and reliance on the coordinated work of photovoltaic systems and mechanical components make them susceptible to environmental influences, which can lead to sudden malfunctions. Mastering scientific daily inspection methods is key to reducing the risk of faults and ensuring stable operation of the equipment. TPON, as a manufacturer of solar water pumps, has summarized the key points for daily inspection of solar water pumps, covering three core modules, which are simple and easy to execute.
Photovoltaic Modules: Ensure Power Generation with Three Steps.
-Observe, Clean, Measure- Inspection Checklist: module surface obstructions, appearance damage, hot spot phenomena, junction box sealing.
-Corresponding Methods:
1. "Observe" the appearance: Stand 5 meters away to look at the module; if there are areas of uneven light and dark, it may indicate a "hot spot"; check the frame for deformation and glass for cracks up close.
2. "Clean" debris: Use a soft brush or rinse with water to remove dust and bird droppings from the module surface. Avoid using hard scrapers to prevent scratching the glass; during the falling leaves season, inspect and clean daily.
3. "Measure" the seal: Open the junction box cover and check for moisture or water droplets inside; if present, replace the sealing strip to ensure the terminals are free from corrosion.
Water Pump and Piping: Three Methods—Listen, Inspect, and Test—to Prevent Flow Interruption.
- Checklist: strange noises during operation, pipeline leaks, clogged filters, water output
- Corresponding methods:
1. “Listen” to the sound: After starting the pump, place your ear close to the machine to listen for operational noises. If you hear a “buzzing” noise or a “clunking” vibration, it may indicate bearing wear; if the noise suddenly increases, check whether foreign objects have entered the impeller.
2. “Check” the pipeline: Inspect each section of the pipeline and its connections, and touch for any water seepage; examine the inlet pipe filter. If there is a large amount of silt or debris on the surface, remove it and rinse with clean water before reinstalling.
3. “Test”the water output: Collect water in a container for 1 minute and compare it to the usual output. If it decreases by more than 20%, there may be pipeline blockage or a drop in pump head, requiring further maintenance.
Control System: Preventing Faults Using the Three Methods of Observation, Touch, and Inspection.
- Checklist: Display parameters, cable insulation, grounding devices
- Corresponding Methods:
1. “Look” at parameters: Check the inverter and controller display to confirm whether the voltage (usually 36V-48V) and current (not exceeding the rated current of the equipment) are within normal ranges. If error codes such as “E01” or “E02” appear, refer to the manual for troubleshooting.
2. “Touch” the wiring: Lightly touch cable connectors with your hand to feel for any looseness; check whether the insulation is aged or cracked, especially near heat sources or areas prone to friction. If damage is found, wrap with insulating tape or replace the cable.
3. “Verify” grounding: Before the rainy season, use a ground resistance tester to measure the grounding resistance; the value should be ≤4Ω. If it exceeds the limit, check whether the grounding electrode is corroded, and promptly add resistance-reducing agents or replace the grounding system.
"Daily inspections may seem simple but can effectively reduce more than 80% of unexpected faults." TPON reminds users to post the checklist next to the equipment and perform a thorough inspection 1-2 times per week. Keep records after each inspection to track the equipment's operating status.
