Routine inspection and regular maintenance of PV power systems are very important. How to properly maintain your solar system during the holidays?
1. Make inspection plans and inspection personnel arrangements in advance, regularly check the overall operation of the photovoltaic power generation system, observe the equipment meter measurement and detection table and monitor the data displayed by the detection system, conduct regular inspections, and make inspection records. Generally, systems with a capacity greater than 80kW need to be equipped with a person to inspect, and systems with a capacity less than 80kW can be inspected by the user. Check to understand the operating records, analyze the operation of the photovoltaic system, determine the operating status of the photovoltaic power generation system, and immediately carry out professional maintenance guidance if problems are found.
2. Observe whether the surface of the battery array is clean, remove dust and dirt in time, rinse with water or wipe with a clean cloth, but do not use chemical reagents for cleaning. Check whether the wiring is off.
3, pay attention to the appearance of all equipment corrosion and breakage, observe whether there is deformation and cracks in the battery shell, whether there is liquid leakage, whether the state of charging and discharging is good, regularly clean the inverter cooling fan Check whether it is normal The method of infrared detection can be used to check the PV power generation arrays, lines and power-using equipment to find out the causes of abnormal heating and fault points.
4. A full set of technical drawings of the photovoltaic power generation system, electrical main wiring diagram, equipment inspection roadmap, etc., as well as the instruction diagram of the main equipment, operation manual, maintenance manual, inspection report, etc., to facilitate the timely search of the relevant maintenance data.
