If not, does anyone have a suggestion for one that can?** A: No, this meter can not run in reverse. **Q: Does this measure rms or average ac?** A: This energy meter measures rms. **Q: This seller is selling a device that cannot accurately measure power in a us based household. only one "hot" lead is being measured and a house panel** A: So use two and add them together. **Q: How many power meters do i need to monitor: phase 1+ n (110v), phase 2 + n (110v), and phase 1 + phase 2 (220v)?** A: hi it depends on your requirement. You can only use one meter to monitor one of the phase + n . Or you can use three meters to monitor each phase + n . ## Customer Reviews ### ⭐⭐⭐⭐⭐ easy to read *by R***S on 29 January 2026* works well, east install, BRIGHT display. great value ### ⭐⭐⭐⭐⭐ Instalaciones *by E***. on 13 June 2026* Utilidad ### ⭐⭐⭐⭐⭐ Très bien *by M***V on 1 May 2026* Utilisé pour enregistrer sur une année l'utilisation de ma wallbox pour recharger une voiture électrique.
