The maintenance frequency of photovoltaic street light controllers depends on multiple factors, including usage environment, usage time, load conditions, etc. Generally speaking, the following are some recommended maintenance frequencies:
Regular inspection: Check the appearance of the controller at least once a month to ensure that there is no obvious damage, corrosion, or loose connection.
Cleaning: Regularly clean the surface of the controller as needed to prevent dust and dirt accumulation. Gently wipe with a clean damp cloth.
Wiring inspection: Check the wiring of the controller every three months to ensure a secure connection without looseness or corrosion.
Waterproof inspection: Regularly check the waterproof performance of the controller to ensure good sealing and prevent moisture from entering.
Troubleshooting: If any abnormalities are found in the controller, such as abnormal indicator lights or unstable output voltage, timely troubleshooting and maintenance should be carried out.
It should be noted that the above maintenance frequency is for reference only, and the specific maintenance frequency should be adjusted according to the actual situation. In some harsh environments or high load usage situations, more frequent maintenance may be required. In addition, it is also important to follow the maintenance guidelines provided by the controller manufacturer.
If you are unsure or unfamiliar with the maintenance of photovoltaic street light controllers, it is recommended to consult professional technicians or manufacturer customer service for more accurate and detailed advice. Proper maintenance can extend the lifespan of the controller and improve the reliability and performance of the system.
