    I like this new meter. Search WANF on ebay ... I've seen it for just $9.99 new recently.

    Nice Meter i like the way it lights unlike the other type of Kw meter.

    I did some testing this morning that others might find interesting. If you want to save every watt, then this might be useful information.

    I think I am going to eliminate the WANF/KAW meters from my system and instead use non-invasing sensing and "zero-watt" monitoring for all my panels.

    Great on the testing. Did not either figure they would use that much power. Thanks.

    Yeah, they designed these power meters to null out the display of their own usage. They want them to read 0.000 kW when no load is attached. That's understandable. My current thought is to buy 6 Efergy CT sensors ($11 each), one for each GTI, and use a rotary switch to select the one feeding the Efergy transmitter. I'd still have one "master" CT to indicate the total real-time watts. This is a non-invasive "zero-watt" solution. I'll also put the GTI cluster on a day-timer so they stay totally off at night.
