All SunPower modules with NE in the model number are specifically listed to be positive or negative ground or ungrounded with transformerless inverters.

HI Dave, You are correct. The Enphase Microinverters bond the DC positive to ground. This is not an issue. Most modules will operate normally with either; no ground bond, the DC negative bonded, or the DC positive bonded. SunPower modules are the exception, with a requirement for being 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.

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> <mailto:lo...@netzerosolar.net<mailto:lo...@netzerosolar.net>>, or 520-237-5040<tel:520-237-5040>?
