Frequently asked questions
What is the SMA DC_SPD_KIT7_T1T2?
It is a plug-in surge protection kit from SMA for the DC side. It combines a type 1 and type 2 arrester and protects the inverter from voltage peaks caused by lightning and switching operations.
Which inverters is the kit suitable for?
The DC_SPD_KIT7_T1T2 is designed for the SMA STP xx-50 and STP xx-US-50 series and is integrated directly into the device as an original accessory.
What is the difference between type 1 and type 2 surge protection?
Type 1 arresters protect against high-energy partial lightning currents in case of direct or near lightning strikes, type 2 arresters against indirect and switching overvoltages. The combined kit covers both protection classes in one product.
Why is DC-side surge protection useful?
The DC cabling of a PV system often runs over large roof areas and is therefore particularly exposed. An arrester limits overvoltages before they can damage the inverter and the module strings.
Who is SMA?
SMA is a global manufacturer of inverters and system technology for photovoltaics. The company offers extensive original accessories such as surge protection kits for its device families.
