Enphase already positive-grounds the module:

Q: The Enphase Microinverter manual states that the device is positively
grounded. Don't most PV modules have negative grounds? Is this a problem
for Enphase?
A: Enphase made the decision to positively ground its microinverters to
minimize corrosion. Because Enphase Microinverters are positively
grounded, they are compatible with both positively and negatively
grounded modules.

Louis,
Can Enphase inverters be positively grounded? I wasn't aware that they
could. Otherwise you have an equipment mismatch problem that can't be
overcome under the listing of the modules and the inverters.

Hi Wrenches,
I'm trying to piece together an SunPower/Enphase job, and looking for up
to 25 Enphase M210-84-208-S12 inverters, which have been discontinued by
Enphase.
If you happen to have any available (or know someone who does), can you
please contact me off-list at lo...@netzerosolar.net
<mailto:lo...@netzerosolar.net>, or 520-237-5040?
Thanks,
