    Enphase Q Series Nighttime Power Draw

    Enphase has decided to not disclose the the nighttime power draw of their Q series micro inverters. The older M series had a small 65mW nighttime draw but the new Q series is significantly more.

    Anyone here know the the specs for the Q series?

    Wait, how do you know it's more, if you're the one asking for the specs?

    I assumed it was more since Enphase decided to drop the disclosure. I guess I have a jaded opinion of how marketing works.

    Just thought someone here has taken an actual measurement. I’ll eat crow and be pleasantly surprised if it is less.

    All I can say is that it will be hard to take a quick measurement because the capacitors in them make for a very low power factor when not outputting. So just putting an amp clamp on it won't do the trick, will give you too high a reading.

    Yes, I understand the low PF.

    I am getting feedback that these new Q series draw "real" watts greater than 5W each constantly.

    If true these are little vampires that put wall warts to shame. I'm hoping this is not the case.
