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.
Example: Smart Meter and TSUN Products integrated with WiFi
Product Components
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 100A. The load current in this circuit cannot exceed this upper limit.
Pre-installation Check
Check the Product and Accessory
Although TSUN's products have passed stringent testing and are inspected before leaving the factory, it is possible that the products may be damaged during transportation. Please check the product for any obvious signs of damage. If such signs are present, contact your dealer as soon as possible.
Check the Installation Environment and Location
When selecting the installation location, the following conditions should be adhered to:
- Install the PEEM-S100 close to or within the home distribution box.
- Avoid electromagnetic interference that could affect the proper operation of electronic equipment.
- Use a mobile phone to assess the Wi-Fi signal strength at the installation site. If the Wi-Fi signal is weak, attempt to install the PEEM-S100 at an alternative location or relocate the Wi-Fi router.
Install the Smart Meter
Steps
- 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) and N (Neutral) cables to port 11 and port 14 respectively. Then connect the CT cable to port 4 (using the Red Cable) and port 5 (using the Black Cable).
- Step 4: Mount the CT onto the correct L cable. The arrow direction marked on the CT should be oriented towards the inverter side.
- Step 5: Connect the Wi-Fi antenna cable to the PEEM-S100. Place the antenna outside the distribution box to ensure a strong Wi-Fi signal.
- Step 6: Upon confirming the correct wiring of the meter, turn on the three-phase switch and the single-phase switch.
