New feature: net energy metering mode



Three Phase WiFi energy meter, WEM3080T will support net metering mode in new version.

Take an example to explain about net metering mode

You installed a WEM3080T in a three phase electricity system. Assuming that the power in each phase remains constant within in one hour as below, and it is importing power from grid on phase A and B, exporting power to grid on phase C,

P1 = 2KW (power of phase A, importing power from grid) P2 = 1KW (power of phase B,importing power from grid) P3 = -3KW (power of phase C, exporting power to grid)

also assuming the power tariffs are as below,

Imported power tariff =0.3 USD/kWh

Exported power tariff =0.1 USD/kWh

we can compare the billing within one hour in normal mode and net metering mode.


  Grid Consumption(kWh) Grid Electricity Bill Exported Energy(kWh) Income of exported electricity Balance
Net Metering Mode 0 0 0 0 0
Normal Mode 3 0.9 1 0.1 -0.8




New model: WEM3080T-400A
