Step 1: Install Current Transformers for mains connection metering

1. Determine the number of CTs required (MEVX02N1P5MCT):
   • For single-phase systems, use 1 CT on the Live wire (L).
   • For three-phase systems, use 3 CTs, one on each phase (L1, L2, L3).
2. Wiring:
   • Connect the CTs to the charger according to the wiring diagram below. Ensure that the wiring is secure and correct. 

Note the location of the CTs. It's essential for them to measure home load and energy surplus from PV inverter. When PV production is higher than home consumption, Clamp Values should be negative as in the picture below.

Step 2: Configure DLM and Solar Charging setting in the APP

1. Download and Install the Morek EV App:
   • Download the Morek EV Tool APP from Google Play or the App Store.
2. Connect to the Charger:
   • Use Bluetooth to connect your device to the charger through the app. If in doubt, follow the article here first.
3. Enable Power Distribution: 
   • Scroll down and set the "Power Distribution" parameter to ON.
4. Select "Sampling Method":  
   • Set this parameter to "CT".
5. Set Home Power Current (A): 
   • Enter the maximum input current of your household (your main circuit breaker rating). This setting prevents overloading your household electrical system.   
6. Enable Solar Mode:
   • In the app, set "Solar Mode" to ECO mode, enabling the charger to use excess solar power for charging.
7. Set Solar Current From Grid:
   • Decide how much grid power, if any, should supplement solar power:
     • Set to 0: Charger uses only solar power and starts charging when excess PV current exceeds 6A.
     • Set between 6A and 32A: Charger combines grid and solar power, with at least 6A from the grid, ensuring uninterrupted charging.
8. Adjust Solar Stable Time:
   • Set "Solar Stable Time" (10 to 3600 seconds) to control the delay before the charger adjusts the charging current based on solar power changes:
     • Shorter times (e.g., 10 seconds) allow quicker adjustments; longer times (e.g., 3600 seconds) increase stability and reduce fluctuations.
   • Example: If excess solar current exceeds the charging current by more than 2A for longer than the set time, the charger will increase the charging current. Conversely, if the excess current drops below the charging current for the set time, the charger will decrease the current or pause charging if it falls below 6A.
9. Save Solar Configuration:

• After setting the parameters, save the settings by clicking "Set."

• Disconnect from the charger by closing the app to allow the charger to restart.

Step 3: Verify Configuration and Operation

    Check DLM Operation:

• Monitor the charger's behavior as household loads vary. It should automatically adjust the charging current to prevent overloading your home's electrical system.

    Monitor Solar Charging Performance:

• Ensure that the charger starts and stops charging based on the available excess solar power.
• Adjust the "Solar Current From Grid" and "Solar Stable Time" settings as needed to optimize charging performance and stability for your solar power and household usage.
