Hi there! I see you’re experiencing the "No data available" message for Month and Year in the Energy Balance on Fronius Solar.web, while production data shows correctly for the Day but imports are missing. I’d like to help get this sorted out.

To better assist, could you tell me:
- How long you have noticed this issue?
- Are you using the Fronius Datamanager or a specific logger device (like the Fronius Smart Meter or CT sensors) for imports?
- Have you recently changed any settings or hardware related to the system?
- Does the daily data show your import values correctly, or are imports missing entirely?

Meanwhile, here are some step-by-step actions you can try:

1. Check Data Logger Status:
- Log in to your local inverter interface or Solar.web portal.
- Verify that the Data Manager or logger is connected and reporting data continuously. Sometimes, if the Data Manager is offline or misconfigured, historical data (like monthly/yearly balances) won’t be updated.

2. Verify Metering Device:
- Since imports are missing, confirm the smart meter or CT sensor measuring grid import is properly installed and communicating with the Data Manager.
- No import data usually means the meter data isn’t being captured or linked correctly in Solar.web.

3. Inspect Date and Time Settings:
- Incorrect date/time on the inverter or datalogger can cause misalignment of historical data.
- Ensure the system clock is correct, as this affects data aggregation for month and year views.

4. Refresh Historical Data Cache:
- Sometimes, the system may fail to update aggregated data. Try logging out and back into Solar.web or clear browser cache for the web interface.
- Also, confirm that there are no active service messages indicating communication loss (you can view these under "Settings" → "Service messages" in Solar.web).

5. Check for Firmware Updates:
- Ensure your inverter and datalogger firmware are up to date, as older versions occasionally have data communication bugs.

If daily production shows fine but imports never appear, the issue typically traces back to the meter setup or data logger not receiving import data correctly. If you confirm all hardware and connections are fine, we can explore advanced settings or consider contacting Fronius support with system logs.

Could you try these and let me know what you find? I’m here to help walk you through any step or dig deeper based on your setup info.

Are you satisfied with this start, or shall we dive into more specifics?
