Regular inspection and maintenance are beneficial for the normal operation and efficient power generation of DC solar energy systems.
Maintenance points of DC solar energy system
1. Maintenance of solar panels
Cleaning work: Clean the solar panels every two weeks to increase the system's power generation. According to the actual situation on site, the cleaning frequency can be appropriately increased.
Inspection and testing: Check each solar panel and solar system circuit and circuit connection to ensure the normal operation of the photovoltaic panel. At the same time, conduct photoelectric conversion efficiency testing.
2. Maintenance of steel supports
Rust prevention treatment: Check whether there is rust on the steel bracket. If there is, remove the rusted part on the surface and then apply anti rust paint.
Tightening inspection: Check if there is any loose screw in the installation part of the solar cell module. If there is, tighten the screw immediately.
3. Inverter maintenance
Status check: Ensure that the equipment is in good condition and ready for use, keep the equipment clean, dry, and away from water and fire sources.
Parameter setting: Regularly check system parameters and make inspection records. If any abnormal phenomena are found, identify the cause of the abnormality and take corresponding measures. When the system encounters errors, promptly troubleshoot and keep records.
Safe operation: During system maintenance, be sure to disconnect the solar cell first and then cut off the load. Do not allow non professionals to open the device for operation or parameter modification.
