[RE-wrenches] Enphase M210-84-208-S12 Inverters Available?

[Nick Soleil]

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 get me wrong: I love nuclear energy! It’s just that I prefer fusion
to fission. And it just so happens that there’s an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it’s wireless! .”

- William McDonough
