4. Funcionament
4.1 Starting the System
- Once all electrical connections are secure, turn on the AC circuit breaker connected to the microinverter.
- Next, ensure the solar panels are exposed to sufficient sunlight.
- The microinverter will automatically start operating when the DC input voltage reaches the start-up voltage (22V DC) and sufficient power is available from the solar panels.
- Allow a few minutes for the microinverter to initialize and begin power conversion.
4.2 Seguiment
The Hoymiles HMS-1800-4T Microinverter can be monitored using the Hoymiles S-Miles Cloud monitoring system. This requires a Hoymiles Gateway DTU (Data Transfer Unit), which is sold separately.
- Connect the DTU to your home network and position it within range of the microinverter's Sub-1G communication signal.
- Register your system on the S-Miles Cloud platform.
- Through the S-Miles Cloud, you can monitor real-time power production, historical data, and system status for each individual module.
5. Manteniment
The Hoymiles HMS-1800-4T Microinverter is designed for minimal maintenance. However, regular checks can ensure optimal performance and longevity.
- Visual Inspection (Quarterly):
- Check for any visible damage to the microinverter casing, cables, or connectors.
- Assegureu-vos que totes les connexions estiguin segures i lliures de corrosió.
- Verify that the mounting is still secure.
- Cleaning (Annually or as needed):
- Gently clean the exterior of the microinverter with a soft, damp drap per eliminar la pols o els residus.
- No utilitzeu netejadors abrasius ni dissolvents.
- Ensure the cooling fins are clear of obstructions.
- Seguiment del rendiment: Regularly check the system's performance via the S-Miles Cloud to identify any drops in power production that might indicate an issue.
ADVERTIMENT: Do not attempt to open or repair the microinverter. Refer all servicing to qualified personnel.
