Product Introduction
System Introduction
The Smart Meter is a power meter that utilizes WiFi communication. It is typically installed in the home distribution box to collect data such as voltage, current, and power consumption from the power grid. This information is then transmitted via the WiFi network to a microinverter or microstorage unit to assist in control functions like zero-export.
Screen Display
The display panel of the Smart Meter shows various information including positive active total energy, MODBUS COM address,voltage, current, power, power factor, and frequency. It also features a flip-screen mode where the screen automatically flips every 2 seconds or with a click.

Product Introduction
System Introduction
Smart Meter is a power meter that uses WIFI communication. It is installed in the home distribution box, collects voltage, current, power and other information of the power grid, and transmits it to microinverter or micro storage unit through the WIFI network. It assists microinverter or micro storage unit in performing control functions such as zero-export function.

Product Installation
Confirm the Phase of the Circuit
If this smart meter is installed on a single-phase power grid, ignore this section and proceed to the next step, “Install the Smart Meter”.
If this smart meter is installed on a three-phase power grid, it is necessary to confirm the installation position of the meter according to the following method. Confirm the corresponding switch and the phase of the microinverter or micro storage unit in the household distribution box. As shown in the figure below, it is necessary to confirm which phase of the microinverter or micro storage unit is in. The smart meter must be installed next to the electricity meter. When the meter is in the same phase as the corresponding microinverter or micro storage unit, the microinverter or micro storage unit can turn on the zero export function.
Method 1:
If the circuits or devices controlled by each switch are clearly marked on each single-phase switch in the household distribution box, the installer can directly find the circuit switch that controls the microinverter or micro storage unit.
Method 2:
If the control circuit of each single – phase switch in the household distribution box cannot be clearly distinguished, the installer can consult the household about the house power grid wiring diagram, obtain relevant information by querying the drawing, and find the circuit switch that controls the microinverter or micro storage unit.
Method 3:
If relevant information cannot be found in the distribution box or drawing materials, the installer can quickly find the corresponding circuit switch according to the following steps.
- Step 1: Connect an easily-observable household appliance (such as an electric fan, desk lamp, etc.) to the socket that is ready to have the microinverter or micro storage unit installed.
- Step 2: Turn on the household appliance and put it in working mode (for example, turning on the electric fan or desk lamp).
- Step 3: Turn off the single-phase switches in the household distribution box one after another, and observe the status of household appliances at the same time. If the household appliance used for observation stops working after closing a single-phase switch (for example, the electric fan stops rotating, the desk lamp goes out), then the single-phase switch is the control switch of the corresponding circuit.
After finding the corresponding circuit switch, install the smart meter on the bus (or connection line) between the three-phase switch and the single-phase switch. For example, if the smart meter is installed in the L1 phase, the wiring should be as follows.
Warning:
The maximum passing current of the Smart Meter is 60A. The load current in this circuit cannot exceed this upper limit.
Install the Smart Meter
Step 1: Turn off the three-phase switch and all single-phase switches of the distribution box.
Danger:
Installers must ensure that the three-phase switch as well as all other switches remain in a closed state during the whole operation process. Meanwhile, be cautious not to touch the exposed conductive part on the grid – side of the three – phase switch to prevent electric shock.
Step 2: Install the Smart Meter on the rail of the distribution box.
Step 3: Connect the L (live wire) line of the three – phase switch to the L ↓ port of the Smart Meter, where L ↓ is the input port, from the power grid to the meter. Connect the L (live wire) line of the single – phase switch to the L ↑ port of the Smart Meter, where L ↑ is the output port, from the meter to the household load. Connect the N (neutral wire) line to the N port of the Smart Meter.
Step 4: After confirming that the wiring of the meter is correct, turn on the three-phase switch and the single-phase switch.
