HI All, For plug in watts/PF meters is there a better or more accurate one that anyone recommends? I've tried the Kill-a-watt and seems to work and be pretty accurate, but haven't compared it to many others. I've been testing some CFLS vs LED and the PF is way better on the LED. For us of

Hi Jay, Take a look at the Fluke 125 Power Scope. It's about $1500. It looks like a pretty sweet meter. I think it will do what you're looking for. Multi-channel DVOM + AC Power + Power Factor + More. The clamp doesn't do DC amps, so that's a bummer. For higher-end things like this, I'm generally

Darryl, The inverter is reducing the real power used by the customer but not the reactive power.   So it does make the power factor worse when you are looking at from the utility meter.  Since most customers don't pay for reactive power it doesn't matter to them.  But some customers do pay for
