4. Configuració i instal·lació
4.1 Muntatge de l'inversor
Mount the inverter securely using the integrated fixed positioning bracket. Ensure the mounting location provides adequate ventilation and is protected from direct sunlight if possible, though the IP65 rating allows for outdoor exposure.
4.2 Connexions elèctriques
Before making any electrical connections, ensure that both the DC power from the PV modules and the AC power from the grid are disconnected.
4.2.1 Connexió d'entrada de CC
Connect the DC output cables from your solar PV modules to the DC input connectors on the micro inverter. Ensure correct polarity (+ to + and - to -).
4.2.2 AC Output Connection (Grid-tie)
Connect the AC output cable from the micro inverter to your electrical grid. The inverter supports both single-phase and three-phase connection methods. Use appropriate grid-tie cable components (e.g., 3*1.5mm² cable with European standard plug).
4.2.3 Multiple Inverters Stacking
The WVC-800W micro inverter supports stacking multiple units. This allows for flexible system expansion without complex wiring. Each group of inverters in the AC box can handle up to 50A. The system branches work independently, meaning if one group is damaged, others continue to operate.
4.2.4 Single-phase and Three-phase Connection Methods
Refer to the diagram below for typical single-phase and three-phase connection methods. Ensure all local electrical codes and standards are followed.
4.3 Monitoring System Setup
The WVC-800W inverter can be monitored via a mobile application. Follow these steps to set up the monitoring system:
- Download the mobile application (scan QR code if provided, or search for 'smartlife' products app).
- Register a personal account within the app.
- Connect the wireless antenna to the inverter. Turn on Bluetooth on your phone and search for the inverter. The blue light indicator on the inverter will flash, indicating a successful connection.
- In the app, select 'Add Inverter' or similar option.
- Follow the on-screen prompts to confirm information and add the device.
- Ensure your phone is in Bluetooth or Wi-Fi status during the setup process.
- Enter your Wi-Fi network credentials when prompted.
- Click 'Next' to complete the installation and customize the inverter's name and account settings.
- The app interface allows control and monitoring of the system.
- Upon successful connection, the blue light of the frequency converter will remain steadily on during normal operation. Occasional flashing indicates best voltage tracking.
5. Instruccions de funcionament
5.1 Estat dels indicadors LED
The inverter features a multi-color LED indicator to show its operational status:
- Red Light (Always On): L'inversor està encès.
- Llum vermella (intermitent): The inverter has not reached the minimum required power for operation.
- Green Light (Always On): The inverter is actively generating power and feeding it into the grid.
- Llum verda (intermitent): The inverter is performing Maximum Power Point Tracking (MPPT) to find the optimal power output from the PV modules.
Normal Working Indication Process: When the micro inverter is connected to the grid and PV modules, the red light will flash for approximately 30 seconds. Subsequently, the blue light will flash quickly (indicating MPPT maximum power point search). Finally, the blue light will remain steadily on, signifying that MPPT is locked and the inverter is operating normally.
5.2 Monitorització remota
Once the mobile application is set up (refer to Section 4.3), you can remotely monitor the inverter's performance, including power generation, voltage, and other operational data, directly from your smartphone or tablet.
6. Manteniment
Regular maintenance helps ensure the longevity and optimal performance of your WVC-800W Micro Inverter.
- Neteja: Periodically clean the exterior of the inverter to remove dust, dirt, and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Comprovació de la connexió: Annually inspect all electrical connections (DC input and AC output) to ensure they are secure and free from corrosion. Tighten any loose connections.
- Ventilació: Ensure that the area around the inverter remains clear of obstructions to allow for proper airflow and heat dissipation.
- Inspecció visual: Regularly check the inverter for any signs of physical damage, such as cracks, dents, or discolored wiring.
