I think so... they are all MC4 from what I remember.. I didn't have a chance to open it yet.
Just finshed wiring a ac cutover.
I wire the output of the enphase inverter (240v) to a ac cutoff. I tied the Sunnyboy ac output to the output of cutoff switch. I can't wire directly into the outdoor because the utility company place a tag on it.
enphase ----> cutoff ---->---------> Outdoor AC cutoff.
