Getting the water proof AC connector for the Micro-Inverter
Each microinverter is supplied with the AC line outdoor cable with two waterproof connectors. The Microinverter connectors can be easily removed to get access to the standard 230V AC wiring (brown - live - L, blue - neutral - N, yellow/green - ground - GND).
Also it may be possible to remove the connector on one end of the micro-inverter, insulate the open end and use the connector to make your own cable to mate with other connector. See also here.
