- Vendor: SMA
Specifications
Product description
The SMA DC-SPD-KIT6-10 is a Type 2 DC surge arrester specifically designed for solar photovoltaic systems with SMA Sunny Tripower X inverters. It provides reliable protection against induced overvoltages, such as those caused by indirect lightning strikes or switching operations, with a total discharge capacity of up to 50 kA and a maximum voltage of 1100 VDC.
Main features
- Type 2 / Class II SPD protection for direct current
- Maximum operating voltage: 1100 VDC
- Total discharge current: 50 kA (8/20 µs)
- Internal thermal protection and visual status indication
- Optional with remote contact for fault signal (model -R)
Advantages or benefits
- Effective protection against induced overvoltages in solar installations
- Quick and easy installation on DIN rail inside the inverter or in an external string box
- Prevents damage to inverters and extends the service life of photovoltaic components
- Compatible with PV systems up to 1100 VDC
- Official SMA approved model, manufactured by Raycap
Purpose or applications
Recommended for commercial and industrial photovoltaic systems using SMA STP X inverters, especially in installations located in areas with medium risk of lightning strikes. It is the ideal complement in installations where type 1+2 protection is already available on the AC side, but specific DC protection against induced overvoltages is required.
