Damage to the PV system due to incorrectly rated fuses
If fuses are incorrectly rated, excessive reverse currents can destroy the PV modules.
• Observe the maximum current values for Sunny String-Monitors when rating the fuses.
• Only install string fuses supplied or approved by SMA Solar Technology AG for Sunny String-Monitors.
Damage to the components due to dust or moisture penetration
Dust intrusion or moisture penetration can damage the components of the Sunny String-Monitor or impair their
functionality.
• Do not open the Sunny String-Monitor during a sand storm, rainfall or humidity of more than 95%.
• Only carry out maintenance work on the Sunny String-Monitor if the environment is dry and sand-free.
• Always lock the Sunny String-Monitor.
• Always store the Sunny String-Monitor in an upright position with the connection area facing downwards.
Damage to electronic components due to electrostatic discharge
Electrostatic discharge can damage or destroy electronic components.
• When working on the Sunny String-Monitor and handling components, observe all ESD safety regulations.
• Wear suitable personal protective equipment for all work on the product.
• Discharge electrostatic charge by touching uncoated, grounded enclosure parts (e.g. at the grounding conductor
connection on the doors). Only then is it safe to touch electronic components.
