208V 3phase circuit question.

  • Question
  • Updated 3 weeks ago
For the Enphase M190, 208V inverters, does each inverter create power for a single phase or does each inverter create 3phase power by itself?
For the M215 I have the same question. Or does the trunk cable wiring pick a phase from every third inverter in the string?
I find the Enphase circuit calculation data sheet to suggest this.

In a 3 phase situation, each inverter puts out power to two legs. The cabling arranges each inverter in order to connect to the next pair. Ideally you have a multiple of 3 inverters to balance the generation, but it really doesn't matter much.

Note the difference between the M190 and the M215. For the M190, you must order the 3-phase version of the inverter. Whereas for the M215, you order the same inverters and order the 3-phase version of the Engage trunk cable.
Sorry to start an old thread but I have a question about this...

What is the difference between a 3 phase M190 and a split phase M190? Are they fundamentally different devices?
