The Sunny Boy Combiner Box is designed to provide many years of trouble-free service.
Performing regular maintenance will help to ensure long life and high efficiency of your PV system.
Maintenance may include:
• Inspection of mounting.
• Inspection of electrical connections and components.
• Cleaning of housing and interior if necessary.
The inspection intervals depend on the location and the ambient conditions.
A device installed in an environment with very dusty ambient air requires more frequent
inspection and cleaning.
