<br>Erika - I don't think you will find any major technical barriers but my understanding is that it will void the warranty on the Enphase units. We installed an AC coupled Enphase system with an SMA Sunny Island and it is humming along just fine.<br>

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!"<br>
