| Warranty | Request current written terms |
The public datasheets describe an expandable warranty but do not define the base term, remedy, registration deadline, or exclusions. Obtain the current written warranty for the exact quoted model before purchase.
The linked datasheet lists 4.6, 5 and 6 kW variants. Ask for the exact-model document before selecting other variants named in this family.
Before specifying this inverter
Check the exact variant’s AC connection, MPPT voltage window, input and short-circuit current limits against the array design. Request current certificates, installation instructions, monitoring options and written warranty terms for the quoted model.
For procurement, include the model, quantity, project location, grid connection and required delivery date in your inverter RFQ.
