Hi Jason,

 

We have paralleled M190 with M215 and have had no comm issues.yet.  Enphase
gave their blessing as well.

Perfect. That's what I thought. No comments on the comm issue, so I assume
there is no issue.

Hi Jason, 

You can do that, but will need to maintain the 15A limit of the M190s.  For
a single-phase, 240V application, with 3 M190s (3*0.8A = 2.4A,) you can
install up to 10 M215s.

Is there any reason I can't do this? I have an existing string of 3 M190's
and want to add 7 M215's. I plan to tie into the same j-box, which has #10
going to a fusible disconnect and a supply side tap. I'll just have to
change the fuse rating.  

 

Any comm issues reported with this setup?

"Don't get me wrong: I love nuclear energy! It's just that I prefer fusion
to fission. And it just so happens that there's an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it's wireless! ."
