Smart Meter-W

MR3-D3-(Wifi)

Smart Meter is a power control device for microinverter system.
It can collect the current grid output power status.
At the same time, it is connected to the home network,
communicates with microinverters under the same network, and
controls the output power of the entire microinverter system.

Consumption Calculation

Smart Meter will collect voltage, current, power, and other
data on the power grid side of the home, upload it to the
server, and display it on the APP and WEB.

At the same time, the monitoring platform will combine the
microinverter power and other data to calculate the
household load consumption data and display it on the APP
and WEB sides.

Zero-export Function

When the anti-reverse flow function is turned on, the
Smart Meter will send the collected power grid data to the
micro-reverse flow in real time through the local network.

The microinverter automatically adjusts the output power
to match the power consumed by the household load. This
achieves the purpose of not transmitting energy to the
public grid, which is the anti-backflow function.
