Pinout for Enecsys Bus Grid Connect Cable, IN-DC-05

What are the wire colors?

The pig tail you show looks to be a European version. It might still work on a U.S. version micro-inverter but the wire colors may be European reference which is probably Hot, neutral, ground, where hot to neutral is Europe's 240vac. Just a guess but likely the ground is U.S. neutral and their neutral and hot are U.S. L1 and L2, 240 vac.

Somewhere on the web I saw Europe's wiring color convention. If I remember correctly, their hot is brown, neutral is blue, and ground is green-yellow which looks like the picture in the link you attached.

(U.S. is Black/Red for L1/L2 with White for Neutral).

So don't confuse Europe's neutral for U.S. neutral. Their neutral to hot is 240vac.

For U.S. version micro-inverter, the neutral should not be grounded to inverter case. I am not sure of European version micro-inverter whether the third ground wire is connected to case. I assume they have the same grounding isolation between neutral and ground until it gets back to main breaker box where they are tied together at service entrance.

So, my guess would be U.S. L1 and L2 tied to their brown and blue, with U.S. neutral tied to their green-yellow.

(you did not put in your profile where you are located so I am assuming it is U.S.). Hopefully you bought U.S. model micro-inverter if you are in U.S., otherwise it probably is not U.L. approved.
