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.
