SMA DC Surge Arrester Type II – Overvoltage Protection for STP60-10 and SHP75-10

The DC surge arrester type II, part number SPD-DC-STP60-10-SV, is a genuine SMA spare part designed to protect solar inverters against overvoltages of atmospheric or switching origin on the direct current (DC) circuit.

Compatibility

This part is specifically designed for the following SMA inverters:

  • Sunny Tripower STP60-10
  • Sunny Highpower SHP75-10

Please verify your inverter's model number before ordering. Using an incompatible surge arrester may compromise the protection of your installation and void the manufacturer's warranty.

Role of a DC Surge Arrester in a PV Installation

Transient overvoltages are among the leading causes of failure in photovoltaic inverters. A type II surge arrester works by diverting residual lightning currents and switching overvoltages to earth, thereby protecting the inverter's sensitive electronic components.

The installation of a DC surge arrester is recommended or even required under applicable local standards, particularly where DC cable runs are long or where the installation is located in a high lightning risk area.

Genuine SMA Spare Part

Choosing a genuine SMA spare part ensures full electrical and mechanical compatibility with your inverter. Third-party components may not meet SMA's internal specifications and could affect the performance or warranty status of the device.

Installation

Replacement or installation of this surge arrester must be carried out by a qualified electrician or certified PV installer, with the inverter fully de-energised before any work begins. Please refer to the SMA technical documentation for your specific inverter model for detailed mounting instructions.
