<div dir="ltr"><div>We haven't had issues yet with the 4th gen systems, although we've only installed a small handful. We have had some painful issues with 3rd gen 5P battery systems; the communication wire seems very touchy. Ultimately, Enphase switched out a component or two on the Controllers. But it took weeks or months and multiple escalations to get to that point in some cases. We've gotten very specific with how we wire the comm wire (follow the drain wire requirements carefully).</div><div><br></div><div>Unfortunately these issues along with really painful commissioning processes caused some team members to lose faith in Enphase's battery systems.
