Review on P3 P4400 Electricity Usage Monitor by Nicholas Serafini
Caution when using with inverter power. A few seconds of a modified sine wave killed me
The standard by which all other power meters are measured. Don't go wrong with any of these, buy one. At least I thought you couldn't go wrong. But I just hooked mine up to a 110V AC source coming from an inverter in a solar PV array and the "modified sine wave" seems to have fried it right away. Now he's dead as a doornail. So this is a little Easter egg for those who actually read device reviews with tons of reviews. Beware of use with modified (cheap) inverters. Worked well with my pure sine wave inverter. I wish there were instructions indicating that this requires a pure sine wave.
- One year trial
- Not bad
