I added a Mieo power meter to my enphase pv array. I'm doing this in lieu of the enphase envoy. This gives me a remote heads up display of output and tracks monthly output. Its only been installed for a day but I noticed last night I had a draw of 90 watts. This is for only 6 enphase inverters. There's a slight chance the inductive clamp was picking power from another circuit but this draw went all night and my other consumption was around 400 watts. I'll try it again tonight with the breaker off. My thoughts if this is correct would be to put a timer on the circuit to save on my overnight draw.
