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.
