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.
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

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.

Sounds encouraging, August. Mahalo.
Are any of those systems zero export by any chance?

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.

Aloha,
I’m thinking about combining the Enphase IQ 7 micros with
a Tesla Powerwall or two.
Anyone out there try this? With bueno or not so bueno
results?
Mahalo,
