The Kill-A-Watt EZ power meter does what it advertizes except it does not work at all with a modified sine wave inverter! I suppose if I could afford a true sine wave inverter I could also afford piles of solar panels, batteries, etc. and I wouldnt need to worry about loads. I will probably keep the thing to use at my house in town but it is useless for what I bought it for; doing a load survey at my off-grid cabin.
