Enphase's Q-25-RAW-300 cable is 300 metres long. A microinverter connector is not included. Like the standard Q cables, the ENP-Q-25-RAW-300 has two 2.5mm2 copper conductors and is double insulated. A standard portrait or landscape cable with connector is required to connect a Q cable to a microinverter. However, these cables will not always be long enough. If you have to bypass a dormer window or skylight, for example, you can connect a length of this cable between the Q cables. Connectors must be fitted to each end of the extension cable to connect to the microinverters.
