• Standard warranty is included. Extended‑warranty packages are available upon negotiation.
• 24‑hour remote technical support and software fault diagnosis are provided.
• Final warranty terms shall follow the signed sales contract.
2. Fault‑Handling Procedure
• When failure occurs, please supply fault codes, photos, videos and on‑site records. Our team will perform remote troubleshooting first for software, communication, earthing and grid‑matching issues.
• If remote repair fails and the defect is confirmed as factory‑caused within warranty, replacement spare parts will be arranged after part‑model verification.
• Low‑value accessories may be scrapped locally with proper records. High‑value core components must be returned to China via consolidated sea freight.
• Local spare‑part installation shall be completed by the buyer. On‑site service by our engineers will incur separate travel‑related charges.
