Quick Enphase M215 output plug question

Coyotefred

Hello!

I'm trying to troubleshoot a possible connection issue in the output plug of my Enphase M215 and it doesn't indicate which of the 4 pins inside the plug/connector corresponds to L1, L2, common and green/ground. If I'm looking down at the top of this plug/connector (with the side stamped "Enphase" and the arrow at the right-hand side of the connector facing UP), which is which?

Thanks for your help/time,

Coyotefred

Yes, I've reviewed this manual before and I don't believe it has the answer. The closest thing I can find is the wiring diagram on page 29, but that diagram doesn't show which pin from the output plus corresponds to L1, L2, common, ground.

Surely someone has an extra piece of trunk cable laying around that could be used to quickly find this out?

Thank you-

They should be color coded http://enphase.com/wp-uploads/enphase.com/2011/05/Enphase_Field_Wiring_Diagram_M215_240v.pdf

Thanks so much. I did just get an answer from Enphase customer service, which I'm sharing here for future reference of other folks...

As far as your pinout question goes. Starting from the labeled pin (will have an arrow) its Line, Ground (which is currently Unused), line & then neutral at the far end.

Ground is unused? For a 240 volt system, usually it's the neutral that goes unused unless you need to split it for 120 volt access.

The later UL specifications for grid tied inverters does require the "neutral" connection even for 240 VAC only inverters.

The standard requires the GT Inverter to qualify the voltage, not only between L1 and L2, but between L1 and Neutral + L2 and Neutral (i.e, something like 106 to 132 VAC from line to neutral). For older installations (like mine), when my inverter was swapped out there was no Neutral wire pulled--So they just connected the "Neutral Sense" to the inverter green wire ground.
