Design Considerations for QD Cable Selection

Each IQ8D Microinverter supports two series connected
PV modules and a maximum of 9 Microinverters in a
branch circuit. IQ8D Microinverter system support multiple
positioning and orientation options for PV modules
through multiple QD cable SKUs. Cable pitch/SKU selection
and Microinverter mounting point need to be decided
according to module positioning and orientation on roof.
