We provide a one-year warranty for the complete transformer. After the first year, we offer an additional two-year warranty for eligible original replacement parts.

During the warranty period, if a fault is confirmed by our technical team to be caused by manufacturing or material issues, we will provide the required original replacement parts free of charge. The additional parts warranty applies only to eligible original parts with confirmed manufacturing or material defects. It does not cover improper operation, unauthorized modifications, external damage, or other non-product-related causes.

For overseas after-sales support, our technical team provides 24/7 response support. Senior engineers can offer one-to-one remote guidance through WhatsApp or Zoom, including video-based troubleshooting and installation support when needed.
