Kill-A-Watt Electricity Usage Meter
Kill-A-Watt
I’ve had one of these for more than a year and for what it does, it’s great. Can’t get any simpler to install! Right now I use mine immediately after the inverter before the load center, to get an idea of battery consumption. Until I get my TriMetric or similar it is great for a quick view. I’ve found the most useful measurements to be kWh and Amps. For some reason it can’t deal with the waveform on some NSW inverters so the frequency measurement is generally not useful for me. There’s another caveat, that if you crank up something really brutal, like a circular saw, it totally freaks out and quits measuring completely until power is removed and reset. And thereby, it loses your total kWh. But alas, for $30, who can complain?
