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 even before dispatch.

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. 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.
