SMA External Fans – Part Number NR-STTEXTFANSET-02

Effective cooling is a key factor in maintaining the performance and service life of photovoltaic inverters. When the external fans of an SMA inverter in the SHPXXX(-XX)-20 or SHPXXX(-XX)-21 series show signs of wear or failure, replacing them with genuine OEM parts is the recommended course of action to restore proper operation.

Compatibility

This external fan kit is specifically referenced by SMA for the following inverter series:

  • SHPXXX(-XX)-20
  • SHPXXX(-XX)-21

Please verify your inverter's exact model reference before ordering to confirm compatibility with this replacement kit.

Why Replace the External Fans?

External fans are critical components in inverter thermal management. A faulty fan can lead to overheating, reduced output power, or automatic protective shutdown. Replacing these components — whether preventively or correctively — helps to:

  • Maintain optimal inverter operating conditions
  • Extend the service life of the equipment
  • Avoid unplanned production downtime
  • Preserve the validity of the manufacturer's warranty conditions

Genuine SMA Spare Part

By selecting part number NR-STTEXTFANSET-02, you are choosing a component that meets SMA's original specifications. The use of genuine spare parts is generally required for warranty-covered interventions and ensures full maintenance traceability.

Installation

Replacement of the external fans must be carried out by a qualified technician, in compliance with applicable electrical safety regulations and SMA's technical documentation. Working on a live inverter is strictly prohibited.

For any questions regarding compatibility or availability, the Wattuneed team is available to assist you.
