<p>Most people I have communicated with say the Tesla battery
solution is extremely hard to obtain, and there are other options
out there. Tesla never responded to any of my inquiries. <br>
</p>
<p>Does Enphase even have a battery option that they sell? My
vendor says no, yet that seem to surprise the Enphase Technical
Support people. I forwarded to them the vendor email regarding
this, and Enphase has not responded. I have four projects that
have asked me to look at a battery solution. Chris<br>

<div dir="ltr">No, we haven't done any zero export. I guess both
the Powerwall and Enphase systems would need to be independently
programmed for zero export? I should add a caveat - all of our
IQ7 systems have been the SunPower branded Equinox type, not
Enphase. The main difference being that Enphase would use their
envoy box and SunPower uses the PV Supervisor 6.

<div dir="ltr">Hi Marco - We have dozens of systems with
this combo, so far no problem. Tesla's AC coupling
mechanism in general seems to be very robust - we've
paired them with many inverter types and brands, and
they always seem to couple up during our grid-off tests.
Since the vast majority of our systems are grid tied,
the real test will be how they will work over the long
haul if we have major grid outages - who knows if and
when that might happen. I've been in PG&E territory
in the Bay Area for about 15 years and can only recall
one or two short (less than one hour) power outages.
