SMA Upgrade kit DC overvoltage protection (type I+II) for STP xx-50 series

This is a retrofit kit for retrofitting DC overvoltage protection in SMA Sunny Tripower STP xx-50 inverters. It protects the inverter and the solar panels from damage caused by lightning strikes or overvoltage on the mains electricity supply.

Key benefits

• Overvoltage protection: Provides double protection with Type I and Type II SPDs, which protect against both direct lightning strikes and indirect voltage peaks.
• Increased safety: Minimises the risk of fire damage and other malfunctions caused by overvoltage.
• Extended service life: Protects the sensitive electronics of the inverter and the solar panels, which extends the service life of the entire PV system.
• Easy retrofit: Designed as an upgrade kit for existing STP xx-50 inverters, allowing for quick and efficient installation.
• Reliable monitoring: The inverter detects the status of the SPD modules and sends a notification in the event of failure, enabling proactive maintenance.
• Compliance with standards: The kit complies with the relevant safety and product standards for DC overvoltage protection.

Applications

This upgrade kit has been specifically developed for use with SMA Sunny Tripower STP xx-50 series inverters. It is the ideal solution for installers who want to provide an existing or new installation with the highest possible protection against overvoltage. It is suitable for both residential and commercial projects where the risk of lightning strikes or grid fluctuations poses a risk to the installation.
