[RE-wrenches] AC Coupling Situation

[Nick Soleil]

Hi Jason and wrenches,

We’ve just released an app note [
http://enphase.com/global/files/Enphase_Application-Note_AC-Coupled
-Battery-Based-Systems.pdf] on how to use Enphase with AC coupled battery
based solutions. The Enphase Energy warranty permits the use of our
microinverters in these AC coupled applications.  Feel free to contact me
off list with any questions you have.

“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! .”
