"direction the power is flowing"
IIRC, the specs on the inverters say they use a VERY small amount of power when the sun isn't out. You may not even be able to get a reading on your Kill-a-Watt.

PS: I do Electronics, I'm not an Electrician.
I'm no electrician either, just EET . I won't speak of other appliances using 240v ac, but in the case of my inverter, the 240v circuit for the inverter carries zero current under normal operation. I have never measured any current in the neutral, with any of my meters. That's why I had to switch things around in order to monitor w/ the Kill-A-Watt. Somewhere in the literature it says the neutral is used for communication.

I have seen nightime increments from time to time from standby loss. Most likely it was close to rounding to the next digit before night and it used enough standby to increment it. I don't count these nightime increments in my production #s I post.
