SERVICE & WARRANTY

Overseas After-sales Support

Designed specifically for overseas distributors and fleet operators.

Technical Support Group

Every order is backed by a support group on WhatsApp: our engineers work through the fault with your team by video call and follow it up until the issue is closed.

Remote Diagnostics

Battery-swap products ship with BMS plus 4G telemetry, so fault data can be read remotely.

Replace First, Return Later

Distributors receive spare units with their first order (1–2% recommended). Replacement parts ship first; faulty units return by sea in batches.

Training & Manuals

Video manuals plus technical training for your local service team.

Warranty Policy

Inverters 2 years · Lithium batteries 5 years · All-in-one systems 3 years — cycle conditions per product are confirmed in your quotation. Within the warranty period, non-human damage is repaired free of charge and faulty parts are replaced free of charge. Fault liability is determined from BMS data; damage caused by misuse, water ingress or operation beyond rated limits is excluded. Any dispute is settled by independent third-party testing.
