| 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.
This family’s linked datasheet specifies 800 Vac and a 1500 V maximum DC input. Check the transformer, grid connection and exact model limits; do not treat it as an interchangeable low-voltage rooftop inverter.
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.
