New Feature of Products

Net Energy Metering Mode

 

 

WEM3080T

The Three Phase WiFi energy meter ! WEM3080T will support Net Metering Mode in new version.

Here is an example to explain about net metering mode .

If you install a WEM3080T in a three phase electricity system, assuming that the power in each phase remains constant within one hour as below, and it is importing power from grid on phase A and B and meanwhile 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)

and 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 with that in 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

 

Please note that the net metering mode can not be implemented by only upgrading firmware of old version, because it needs to upgrade both the metering module firmware and wifi module firmware. Wifi module firmware can be upgraded by user but the metering module can only be upgraded in factory. So the old version can not be upgraded to new version by user directly.
