For the averages can this meter run in reverse if monitoring the AC side of solar inverters? If not, does anyone have a suggestion for one that can?

No, this meter can not run in reverse.

Does this measure rms or average ac?

This energy meter measures rms.

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

So use two and add them together.

How many power meters do i need to monitor: phase 1+ n (110v), phase 2 + n (110v), and phase 1 + phase 2 (220v)?

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 .

Works very well. Well worth it.

These work excellent. I track KWh for billing energy usage in my office. It is accurate and matches my Fluke meter in all respects and does not cost 5,000. Nice to have permanent mount... I mounted them (2) in a box external to the power panel. I like the Din rail installation. Very clean

Positively surprised

This device is working very well and as expected. Easy to connect and a nice colorful display that is easy to read. It is taking up 4 halfslots in a electrical cabinet (mounted on a DIN rail)

Preciso y útil

Este medidor es una opción optima para saber el gasto diario/mensual de electricidad y poder compararlo con la factura de la compañía y también conocer al momento el consumo de los electrodomésticos y así intentar ahorrar en la medida de lo posible. Fácil instalación y la numeración con colores diferentes lo hace agradable y atractivo. Estoy contento con la compra y con el desempeño del medidor.
